DETAILED DESCRIPTION

Before describing the invention in detail, it is to be understood that the phraseologies and terminologies employed herein are for purposes of description only to support an enabling disclosure, thus should not be regarded as limiting.

. '

For purposes of this disclosure, “pool” or “pool water system” designated by reference numeral P is defined herein to generally mean any water system or facility, natural or manmade, that is used for recreational or instructional purposes/activities such as swimming pool, natatorium, lido, swimming bath, bath, jacuzzi, sauna, bathtub, spa, wading/diving/sliding water facilities, or manmade or natural water catchment such as ponds, water way or seafront, and other recreational, sporting or instructional pool water facilities. Such pools or pool water systems as herein defined are mainly for serving communities, apartments, condominiums, clubs, spas, camps, schools, institutions, parks, hotels, motels, recreation centers, water and leisure parks, etc.

Referring now to the drawings in detail wherein like reference numerals designate the same parts or elements all throughout the description, there is shown in FIG. 1 a system for water disinfection and/or energization, especially for pool or pool water system generally designated by reference numeral 10, 1s comprising mainly one or more entropy-inducing water energizer 11 being provided and disposed at a strategic location and/or position therein for effecting water energization, thereby introducing metabolic entropy energy into the pool water W that retains and stores therein the energy resulting in an entropically energized pool water W whose metabolic entropy energy is capable of being transmitted to pool user(s). The water energizer 11 can be adapted for energizing a pool P or pool water system P’ as herein defined above, but for best mode, result and/or effectiveness, the water has to undergo first disinfection process/operation by using a water disinfecting means 12, mainly in form of electromagnetic (EM) wave emitting disinfector 12a preferably in combination with one or more other water filtering and/or disinfecting devices 13, being provided and disposed at a strategic location and/or position therein, i.e. specifically, in the pool P or pool water system P’, for effecting water disinfection with immediate and long residual effects, thereby making the water substantially, if not completely, free from contaminants. Actually, the water energizer 11 and disinfecting means 12 are each capable of being operated and adapted individually or collectively in combination (the best mode of the invention) in the pool P or pool water system P’.

. i

As shown in FIG. 1, the main elements of the system 10 are disposed in strategic locations and/or positions with respect to the pool P mainly for functional effectiveness and efficiency such that the water energizer 11 has its water outlet portion being connected to the pool P and its water inlet portion being connected to the disinfecting means 12 or disinfector 12a downstream. In between the energizer 11 and disinfector 12a, a water activator for skin cleansing 15 branches out and is connected to the pool P. Downstream of the disinfector 12a is/are UV disinfector(s) 13b with which the disinfector 12a is more preferably combined resulting in a combined UV-EM-wave-emitter disinfector 12b, and filtering device(s) 13a, including an optional heater 13c disposed upstream of the filtering device(s) 13a whose downstream side is connected to main drain(s) 16 of the pool P through a pump 17. The UV dosage applied is preferably according to the clean drinking water disinfection standard, and its power may vary according to makers’ UV lamp efficiency.

The water energizer 11 is preferably in forms of low frequency (LF) electromagnetic (EM) wave, i.e. ranging from 102 — 10% Hz, from EM wave generator 11a, DC or AC electrolysis 11b, strong magnetic field from electromagnet or permanent magnet 11c or natural electromagnetic wave emitting materials 11¢’, other suitable entropy-inducing devices/materials, or any combinations thereof. For the preferred embodiment of the invention herein disclosed, it is the electromagnetic wave from electromagnetic wave generator 11a as the more preferred entropy-inducing gadget or device adapted.

Energizing the pool water W using the entropy-inducing energizer 11 is a main teaching of the invention. So far there is no pool system as defined above that is able to provide metabolic energy into the pool water W that does not make use of enthalpy-energy energization process which has many drawbacks as aforediscussed. This invention energizes the pool water W with entropy energy to supplement, especially the user's/human body metabolic energy, preferably at the side stream or by direct energization of the pool water W, depending on the water system configuration and the size of the pool as shown in FIG. 1. In essence, entropy energy is used to stimulate the metabolic process of human cells, hence, it has important role in healing processes/ practices in the medical field such as pain relief for post operation, that is due

. i to the entropy energy input. When the human metabolic process is promoted, it includes accelerating the anabolic process and catabolic metabolic processes in our body. These metabolic processes accelerated the growth of cells for tissue regeneration, etc. For example, when people go for exercise, metabolic process is stimulated and triggers the production of endorphins in their bodies that gives the good feeling.

When heating water, the enthalpy energy is inputted or imparted into the water and heat energy primarily accelerates the translation energy of the water molecule. It has minimum effect on the vibration and rotational energy of the water molecule, which means heat is increasing the enthalpy part of the total free energy, but it has minimum or no contribution at all to increasing the entropy energy of the water/water molecules.

Entropy energy is simplified and considered as the “randomness” of molecules, or molecular vibrational/rotational internal energy (entropy). In plant's photosynthesis metabolic pathway, it is the use of entropy energy of UV (an electromagnetic wave) from the sun's energy (taken by the plant cell's chlorophyll) instead of its heat energy (enthalpy energy), that the plant converts

CO2 and H20 to produce glucose for its Calvin cycle. Actually, metabolic process is common for all living forms. Fish, animals, human and plants are alive because the metabolic process is continuing in their bodies. Once the metabolic process stops, all living forms would be dead. The beneficiary parties, plant, fish or animals, are not subjected directly to the high intensity close field treatment. They would only use the residual energy released by the treated/energized water for metabolic process purposes.

In human body metabolism process, thermal energy enthalpy supplied to the user's body just like in physical activities is used to supplement his/her metabolic energy just like in hot spa. While thermal or heat energy induces the same metabolism or produces good feelings similar to what one feels after an exercise, using heat (enthalpy) energy has many drawbacks and disadvantages as aforediscussed. Hence, it is for the purpose of overcoming such disadvantages that the invention came about in using entropy, instead of enthalpy or heat energy for energizing the user's body. The supplementary n { metabolic energy derived from entropy energy eliminates the negative side effects associated with heating or elevating human body temperature. This entropy energy of the invention can be obtained by energizing the water or pool water P in preferred various ways such as using low frequency electromagnetic wave, and making/using the energized pool water W as a medium and storage for entropy energy which is then transmitted to the user(s) for metabolic benefits.

At molecular level, water molecules in general are susceptible to low- frequency electromagnetic wave below the 100 Hz, causing their hydrogen bonding or bonds to vibrate, and water clusters arrangement to change resulting in the induced water energization that can last for a sufficient period of time of up to few months retention time. Water in liquid state is inter-bonded by their intermolecular hydrogen bonds under a dynamic and constant changing state even at room temperature. The grouping of these inter-bonded water molecules is called water cluster. This intermolecular HO attraction force or hydrogen bond due to hydrogen end of the water molecule is more positive electrically, and oxygen end is more negative, hence, attracting the opposite charge end of the neighboring H2O molecule. Such intermolecular hydrogen bond is basically an electron attraction force without any physical matter presence. When this electronic hydrogen bond is subjected to or energized by an external low-frequency fluctuating electromagnetic wave or field, it responds to such low-frequency fluctuating wave/field changes. Since the low-frequency wave fluctuation/frequency changes in the order of thousands to hundreds of thousand time per second, the hydrogen bond of the water therefore have to respond in the similar order, causing the hydrogen bonds to vibrate. When the hydrogen bonds vibrate, the entire water intermolecular bonds become more active or are activated. Some of the hydrogen bonds are broken in this process, but some are created, thus, the water clusters’ sizes are changing more vigorously when the pool water W or clusters are energized by low-frequency electromagnetic or magnetic wave. Therefore, saying that the bonds between molecules are becoming stronger does not accurately or exactly describe the clusters’ changes, it is the statement saying that water molecular clustering are becoming more random that better describes such changes. In the

Cow { thermodynamic second law, when the molecular state is more random, it follows that the entropy energy is increased.

As enthalpy energy is known to be a different energy form from that of entropy, it is by scientific fact that when the water hydrogen vibrates, its entropy energy is increased, but its enthalpy energy is not necessarily increased.

However, the total free energy of a process consisting of both enthalpy and entropy is increased. In general, using external thermal energy input to molecularly excite water is an efficient manner of increasing the water enthalpy, but heat is less efficient in increasing the vibration energy entropy of the water molecules. It is by using suitable low-frequency wave, e.g. magnetic or electromagnetic wave, that the vibrational energy entropy of water is efficiently increased, but without increasing its enthalpy energy. Specifically, when the water molecule bonds (O-H) vibrate as induced by the EM wave treatment, such vibration changes the inter water molecular bond attraction force (hydrogen bond), hence, water clusters are rearranged.

In usage, this stored entropy energy in the water is dissipated and transmitted to its surrounding or objects, especially the user(s), having lower free energy. The dissipation of entropy energy from the energized water to the body of the user(s) can be in a slow or fast manner preferably by direct contact or immersion in the bulk or pool water, or using pressurized dissipation or spray nozzles 14a, respectively, as discussed in detail in the succeeding description.

Electromagnetic wave from the electronic electromagnetic wave generator 11a covers a full range of frequency and for practical purposes, ionization frequency range is not considered. All other ranges of electromagnetic wave have some degree of excitation, but for energy efficiency consideration and electronic components limitations, frequency range from 10? to 100 Hz is the preferable and practical range for excitation purpose. In fact, water molecules readily respond at such frequency range. Further, this electromagnetic wave can be fixed or pulsating time-varying frequency range with sweeping frequency of 0.1 to 1,000 or 10% Hz, and in sine wave, rectangular, triangular, or random.

. f

Load 18 which is used to introduce the energy into the pool water W can be capacitance load, inductance load or combination of both such as emitter load 18a placed in the water W as shown in FIGs. 2A-2C. A DC output power supply 23, which is converted from an AC power supply 23b through a rectifier 23a is used to power the low frequency electromagnetic wave generator 11a in energizing the pool water W through the load 18. Typically, the capacitive load is using two or more low frequency electromagnetic wave emitter/receiver pairs 19 placed in the pool water W to be energized. The emitter pair 19 has its emitters or emitter load 18a (shown in FIG. 2A) being closely and spacedly installed in an emitter chamber, and have approximate power/capacity of about 0.2 kw per 10 cu.m/hr flow rate. The energization can be arranged in either side stream or main stream. Once there is low frequency wave travelling in the pool water W between the emitters/receivers pairs 19, the pool water W starts to get energized. For the inductive load, typical inductor coil load 18¢ or coil load with ferrite core 18b is preferably used and placed in the water W or close to the water W to energize the water W, but other coil types may also be used such as inductor coils 28 hollow conduit, coil wrapping on other materials, etc. The inductor coils 28 in hollow conduit or wrapped on ferrite core is used for energization. The ferrite core can be in different geometrical shape to suit the different site constraints. One or multiple inductor coils 28 can be arranged in different layout in the tank or chamber 29. Electrically the coils may be connected in series or parallel to suit the PCB output limit as shown in FIG. 4B.

Pool water W passes through or outside the coils, hence, in certain cases the coils 28 can be arranged outside or externally of the pool water W. As long as the water W to be treated is within the electromagnetic field influence of the coils, the water W can still receive the entropy energy from the low frequency wave.

Strong magnetic field 21a from permanent magnet or electromagnet 21 is also capable of vibrating or energizing the water molecule, and increasing the water vibration energy as shown in FIG. 3A. Preferably, for a better efficiency, the water W is made to perpendicularly pass through or cut across the magnetic field 21 at an appropriate flow speed. The permanent magnet and electromagnet 21 can also be arranged or disposed outside the water chamber as long as the magnetic field 21a is cutting across the water flow. In certain applications, the permanent magnet or the electromagnet can be clamped or coiled directly onto the water pipe, respectively.

Electrolysis, i.e. DC and AC types, also introduces or induces entropy energy into the pool water W as shown in FIG. 3B. DC electrolysis is carried out with membrane or porous/semi porous partition between its large anode A and small cathode C, producing alkaline and acid water having entropy energy imparted therein in the cathode and anode compartment, respectively, and with pH changes used to controllably correct/adjust the pool water pH and to energize the pool water W. The anode compartment water pH can be controlled at no lower than pH 4 by adjusting the anode/cathode exposed area ratio and also the flow rate of the water. On the other hand, AC electrolysis with low frequency switching also imparts entropy energy into the pool water W, but it does not change the water pH. In AC electrolysis which does not use low frequency wave generator, only DC current is passing between electrodes, but there is provided mechanical or electronic switching device to reverse the DC polarities. The electrodes can be in various geometrical shape to suit different site condition needs, and are made of materials such as metal oxides, platinized titanium/niobium, other semi-permanent electrodes, or combinations thereof.

While electrolysis is able to impart entropy energy into the water, it is an electrochemical process which may generate chemical byproducts such as chlorine gas or hypochlorite if chloride is present in the water. In such case, the negative effect of these byproducts must be evaluated to determine its suitability for the desired application. Thus, chlorine or chloride must not be present in the water if electrolysis is opted as the water energizing process.

In nature, natural electromagnetic wave emitting materials 22 such as natural mineral crystals that emit FIR (Far InfraRed) electromagnetic wave when excited by energy input as shown in FIG. 3C. One example is finely grounded powder of tourmaline (composed of lots of crystals) that emits FIR when there is energy input such as heat from human body. Another example is piezoelectric quartz or rock crystal quartz that releases electrical charge

(entropy energy) when stressed mechanically. Ceramic or Mai Fan stones also have the same FIR- emitting property.

As shown in FIG. 3C, the disinfected pool water W (shown by the arrow

W1) is made to pass through the natural electromagnetic wave emitting materials 22 that are formed into different geometrical shapes or in loose forms.

These materials 22 are preferably placed in a chamber 22a and the water W to be energized is then made to flow therethrough to undergo the energization process. The chamber 22a is sufficiently sized to ensure that the water W receives sufficient treatment within its maximum retention time for energization that depends on the material 22's emission strength. The materials 22 may also be placed directly in the pool P in an exposed or concealed manner, the latter using non-metallic enclosure to prevent unwanted emitted energy absorption that would incur if metallic enclosure is used.

There is preferably provided a means for transmitting the metabolic entropy energy 14 in the resulting energized water (entering into the pool P as shown by arrow W2 in FIG. 1) to pool user(s), which is in forms or ways such as immersion of the user(s) in the energized water, pressurized spraying of the energized water, aeration process, or other suitable metabolic energy dispersions such that the dissipation of energy from the pool water to the user(s) is through skin contact underwater or in space above the water surface.

Further, the pressurized spraying adapts the types of dissipation/spray nozzles 14a such as spiral, orifice, venturi, mist, linear, other suitable nozzle types, or any combinations thereof. More preferably, spiral nozzle is adapted for the illustrative example herein disclosed, and/or the aeration process adapts the use of aeration tubes and/or air stones, producing air bubbles, preferably disposed at the bottom or side of the pool P. Aeration needs air to produce the air bubbles and it takes place in the water and it can dissipate energy in the water W. On the other hand, nozzle spray does not require air and its water dissipation process takes place at above water area. It is just a constriction process that drops the pressurized water to a low pressure environment, and more importantly, the process creates lots of surface areas through its dissipated fine droplets or mists. With the increase in surface areas, dissipation of water internal energy can take place more efficaciously.

Unlike heat energy that can be dissipated by convection, radiation or conduction, entropy energy stored in the energized pool water W is dissipated by pressurized spraying or direct water immersion in which the transfer or transmission of energy is from higher to lower energy level. When entropy energy of the energized water W is pressure-sprayed through the orifice, venturi, spiral/cyclonic nozzles or very fine mist nozzle as mentioned above, more free water/air interfaces are created by the mist or fine water particles, causing their hydrogen bonds to be re-orientated and charged, such that their high entropy energies are transferred to their surrounding or users nearby having lower entropy energy level. This is the reason why users or people nearby some water splashes, waterfalls or sea surfing areas, experience good metabolic feeling.

Aside from using the pressurized dissipation or spray nozzles 14a, other dissipation methods such as cavitation, high waterfall, tidal wave method or fine bubbling aeration can also be used to bring the entropy energy out from the energized water W into the air/water interface and nearby surrounding.

Generally, such energy dissipation methods effectively and efficiently facilitate the release of the densely packed entropy energy in the energized water W to its surrounding.

When the users are immersed in the entropy-energy energized pool water W, entropy energy is transmitted to their bodies having lower entropy energy level. The depletion of energy from a charged/energized water when a human hand is put or immersed thereinto is shown in the FTIR spectrometer graph in FIG. 5. This is a way of releasing entropy energy from water to human body that is milder and slower compared to that of the pressurized spraying that is the faster or quicker way.

All of the above mentioned methods of entropy energy dissipation can be adopted either individually or in combination. In using dissipation/spray nozzles 14a, mist spray or spiral water spray whether vertical upward, slanting, or downward is preferably used, and can also be used as decorative features.

Such dissipation nozzles 14a can be arranged above water, semi-submerged in the pool P or in its vicinity or away therefrom, while the dissipating aeration, if also preferably used in combination thereto, can be arranged in the pool P at any strategic location as long as it is not interfering with the pool water users’ activities.

With the bubbles they created, the aeration or bubbling tubes or air stones in the pool P or in the air uplift system are similar to pressure-spaying methods that release the entropy energy at the water particles’/mists’ water/air interfaces. They differ in that the when air bubbles in the pool water W rise to the water surface, the entropy energy released into the bubbles would be transferred to the pool water surface.

In an energizing chamber, metabolic entropy energy is imparted into the water W, and consequently increases the pool water W's internal vibrational energy. This increase in internal energy is stored in the charged/energized water, hence, detectable by the FTIR (Fourier Transform InfraRed) spectrometer as shown in FIG. 5. The entropy energy increase in the water can be detected by the FTIR spectrometer. When water is excited by the low frequency wave, the vibration energy of the water increases as reflected at the higher absorbance peak at certain wavenumber, e.g. between 3600 to 3200 cm. In general, when the water is not energized, the peak of the graph shows almost the same in series of test. As shown in line graph 5 in FIG. 5, with water in energized condition, the line graph 5's peaks 25 are either higher (for peak 25a of charged water curve) or lower (for peak 25¢ of discharged water curve) than that (peak 25b) of the untreated water curve, and the area under the curve may be expanded. This shows that the water hydrogen bond is undergoing or in a vigorous vibration state, indicating that the water is energized, but when a human hand is put into the charged water, the water's entropy energy is depleted to a lower level as a consequence of the energy being transferred or transmitted into the hand. As aforediscussed, the energy in the water is gradually transmitted to the users’ bodies if the users are immersed in the pool water W, or is speedily/quickly and rigorously released to the nearby surrounding through pressurized spraying or through aeration process.

For the disinfecting means 12 to be more effective and efficient, the low frequency (LF) electromagnetic wave-emitting disinfector 12a, i.e. ranging from

108 - 108 Hz and more preferably 104 - 105 Hz, is preferably in combination with the filtering device(s) 13a, the UV (ultra-violet) disinfector(s) 13b, other suitable disinfecting devices, or any combinations thereof. More preferably, the combination of both the electromagnetic wave-emitting and UV disinfectors, 12a,13b have immediate and long residual synergy disinfection effects that meet the most stringent water pool algae and/or bacterial/micro-organism control requirement. The inductor coil may be used instead of the emitter pairs 19 resulting in more or less the same combined disinfection effects. This long residual disinfection effect will last for days, and since the poo! water W is treated repeatedly for at least once every 6-12 hours, the disinfected water W has sufficient residual disinfection effect, keeping the unwanted bacteria and organisms under control as shown in FIGs. 6A and 6B that complies with the international pool water disinfection control standard. The bar graph 6A and line graph 6B in FIGs. 6A and 6B, respectively, show that for a period of up to 13 days, the presence/number of unwanted bacteria/organisms in the treated pool P significantly remains at a controlled and acceptable lowest level 26 that is, in fact, becoming negligible or nil as shown by the significantly decreasing number of organisms in FIG. 6A. The filtering device 13a, which is the first or initial gadget/device of the disinfecting aspect of the system 10, is selected from any one or any combinations of sand filter, cyclone separator, and other suitable fine mesh filters.

Such disinfecting means 12 as embodied in the system aspect 10 of the invention is another main teaching thereof, using only physical disinfection process (non-chemical based), yet it is highly effective and has long lasting disinfection effect. No chemicals is used in the disinfection process/operation of the invention, but it is able to work in conjunction with chemical disinfectant(s).

This is to prevent and/or avoid the following negative side effects or factors associated with the use of chemicals, to wit: health risk, unpleasant exposure to chemicals, risk in handling the chemicals that may result in chemical burns, secondary pollution, and tedious maintenance procedures and chemistry knowledge, among others.

The long-lasting disinfection effects of the invention is for both pool water bacteria and algae eradication, prevention and/or control that meet the nd following pool system's standard requirements, to wit: the ability to control the bacteria growth effectively, sufficiently and practically long residual disinfection effect, certainty or assurance of no bacteria/algae regrowth, and in the case of outdoor pool, effectiveness of algae growth/regrowth control.

Conventionally, pure physical water disinfection method is almost exclusively UV treatment, although needing high energy consumption, which is only effective at the point/area of treatment and not away from it such as those attached to the pool structures, and has no sufficient residual disinfection effect. Hence, using UV treatment alone cannot be relied upon for an effectively complete disinfection of pool water. Other physical methods such as cavitation or ultrasound are not common for water disinfection due to energy requirement and effectiveness issues. Ozone or copper silver ionization are considered as chemical treatment.

For disinfection purpose, UVC is the effective frequency range, but UVC is also harmful to human beings or users if exposed directly thereto. UVC disinfection is therefore carried out in a confined chamber not accessible for direct contact with users. This means that UV can only be installed at specific location within the water system, but not accessible to the pool water users.

This further hinders the algae and bacteria control in the whole pool system P, especially for bacteria colonies in the biofilm in the water system and outside the UV treatment chamber. UV disinfection also lacks the efficacy in controlling multiplication and regrowth of organisms after treatment, hence, not suitable to use alone in pool water disinfection.

As discussed above, the effectiveness, efficiency and/or completeness of the disinfection aspect of the invention is/are achieved by combining filtration, UV (which is basically used to enhance the immediate kill effect), and electromagnetic wave emitter disinfection processes/operations, with the electromagnetic wave emitter as the main component, but the latter can readily be used independently.

In operation, the first stage is to use the filtering device(s) 13a in forms such as sand filters, cyclone separators, and/or other fine mesh filters as aforementioned to filter off unwanted larger particles, objects, or organisms..

“ 0

The filtering device(s) remove contaminants of sizes greater than 50 micron, reducing the load to the subsequent combined UV and electromagnetic wave emitting disinfectors 13b,12a or UV-EM-wave-emitter 12b. Any existing filtration system in the pool water system P can also be used as the filtration unit for this purpose.

While filtering device(s) 13a is/are good equipment/gadget to trap and filter the undesirable substances/contaminants in the pool water W, they are also ideal habitat for bacteria to flourish, and for biofilm build-up in the filter, especially sand filter. For effective disinfection, it is therefore important to control the bacteria growth in the filter. For this purpose, the emitter pairs 19 may be installed inside the filtering device(s) 13a to disinfect and control bacteria growth.

In the second stage, the disinfection approach for bacteria and other organisms or microorganisms is as follows: e application of emitted low frequency electromagnetic wave (from the disinfector 12a) having disinfection function with long residual effect and the advantage of controlling the multiplication and regrowth of bacteria/microorganisms at disinfection frequency range of 10° to 100

Hz, preferably 1001 to 100 Hz as aforementioned; » utilization of the good instantaneous kill effect of the UV disinfector 13b for immediate removal of bacteria/microorganisms, hence, enhancing the overall disinfection effect although electromagnetic wave emitting disinfector 12a can be used alone without UV; and e using both UV and electromagnetic wave emitting disinfectors 13b,12a in combination or the UV-EM-wave-emitter 12b, resulting in the synergy effect of combined UV and low- frequency wave disinfection treatment, meeting the most stringent 10-50 micron micro algae control requirement.

In UV treatment, either pure UVC or combined synergy effect of UVC, UVA and UVB can be used. The UV treatment is carried out in the UV chamber 27 and fitted inline, either side stream or main flow line. Generally, though the pool water W is very much more polluted than clean drinking water, the UV x dV 8 dosage used in the invention is still lower than the standard UV dosage used for clean drinking water disinfection standard practice mainly due to the synergy effect of UV and low frequency wave disinfection.

The low frequency electromagnetic wave emitting disinfector 12a has the emitter pairs 19 being very closely spaced apart by few millimeter spacing, preferably not exceeding 10mm apart, and the current flow density between each pair of emitters being not be less than 1 amp per sq. m., preferably more than 10 amps per sq.m. max. current that is limited by the capacity of the wave generator’s electronic component capacity. When flowing through this closely spaced emitter pairs 19, the water W is disinfected for both bacteria and algae.

The higher the applied voltage gradient across the emitter pairs 19, the better the disinfection effect produced. The preferred absolute minimum voltage applied across the emitter pairs 19 does exceed 24V while the safety limit is not to exceed 60V.

Frequency range applied is another factor in ensuring good disinfection effect such that for the invention, the time frequency range applied is preferably in the 100 to 100 Hz range as mentioned above. Hence, with such arrangement of the emitter pairs 19, high potential gradient and current density, and correct/ proper frequency range, good immediate and long residual disinfection effect is readily achieved.

The immediate kill effect, especially for the algae (phytoplankton), is defined as “dead” only when it is classified as “dead” with CMFDA fluorescent staining dye test, i.e. with completely no metabolic activities at cellular level.

This also ensures that there is no regrowth of their cells in the recirculating pool water system P’.

When the low electromagnetic wave emitting disinfector 12a is used in conjunction with the UV disinfector 13b, effective and complete bacteria/algae disinfection effect with long lasting residual effect is achieved with very low power consumption. For a flow rate of 500 cu.m/hr, if pure UV is used to achieve the required disinfection result without residual effect, approx. 140Kw power is needed. But with the synergy disinfection effect of the combined wave vo emitter and UV disinfectors 12a,13b or UV-EM-wave-emitter 12b only 30Kw is needed for the same, if not much better, disinfection effect.

Inductor coils electromagnetic wave treatment lacks the ionic current in water, hence, it has poorer efficacy in the immediate killing of organisms compared with the electromagnetic wave emitter treatment. However, if the former is used in conjunction with UV, it is able to control the bacteria/micro- organism multiplication rate in the frequency range of higher than 10° Hz, preferably higher than 100 Hz, and the pool water flow throw the close vicinity of the coil such that the electromagnetic flux density and strength is dense enough to perform the disinfection effect. The preferable magnetic field strength where water is passing through is preferably not less than 10 gauss.

However, if using coils without the emitter pair 19, the UV strength needs to be increased above the clean water disinfection dosage depending on the algae species and population. The above treatment is effective for both bacteria, including Legionella bacteria, and algae eradication and control.

As aforementioned, if coil arrangement is used, the coil may also be placed outside the chamber such as wrapping it directly on the water pipe or using the ferrite core coil and clamping it onto the pipe. In principle, the electromagnetic field so produced has to cut into the water or water flow path.

Further, if emitter pair is used for energization, the emitter pairs 19 need to be placed in the water flow instead of outside the chamber, and the spacing between the emitters 19 can be made further apart than in that of the disinfection chamber as ionic current flow is less critical in energization process.

To improve the cleansing effect of the pool water W such that the user(s) would have a softer and smoother feel of skin after soaking in the pool water

W, there is also preferably provided the water activator for skin cleansing 15 disposed at a strategic location and/or position for effecting water cleansing of the disinfected pool water W (shown by the arrow W1), letting the disinfected water to undergo a ferrite core coils electromagnetic field treatment resulting in a cleansed pool water W (shown by an arrow W1’ in FIG. 1). In operation, the water activator for skin cleansing 15 is in forms such as ferrite core coils oY electromagnetic wave, preferably having frequency range of less than 104 Hz, more preferably lesser than 2 KHz; weak permanent magnet, infrared (IR) emitting materials, ceramics, weak strength DC electrolysis, other suitable water activator for skin cleansing, or any combinations thereof. For purposes of this disclosure, the ferrite core coils electromagnetic wave is more preferably adapted/used.

With weak static magnetic field or weak time-varying electromagnetic field treatment, water to solute reactivity is increased and the water to water intramolecular attraction free energy is reduced. This improves the water cleansing effect and this is shown in the reduced water surface tension reading as well as FTIR curve which is showing a lower peak at the 3200 to 3600 wavenumber range. However, this does not mean the total free energy in the water which includes the bond energy between water and solute and water to water is reduced. With the reduced water surface tension or water to water hydrogen bond strength, it is implying that the water hydration capability is increased, or it is easier for water to dissolve the solutes, or hydrate the dirt etc. for removal.

For this purpose, the pool water after disinfection has another side stream line that goes through a ferrite core coils electromagnetic field treatment in a disposition or set-up as described above. The treated water which has the good cleansing property goes into the pool P for better skin cleansing effect.

To effectively achieve the cleansing effect, the frequency range use is preferably less than 10,000 (10%) Hz, preferably lesser than 2 KHz as mentioned above. The current passing through each coil is preferably less than 2 amps, while the voltage applied across the coil is preferably less than 12V

DC. If volume of water is large, more than one coil may be used as this would ensure a good cleansing effect for the cleansed water.

Other methods such as using weak permanent magnet, IR emitting materials, ceramics, weak strength DC electrolysis etc. as described above may be used but their energy level shall be sufficiently low for promoting “water to solute” reactivity.

For heated pool, the pool water temperature can be lowered to exceeding 36°C, yet it is still capable of providing the supplementary metabolic energy benefits. This is particularly useful for users who have pre-medical conditions.

After being completely disinfected, the disinfected pool water W needs to be energized by low frequency wave to impart entropy energy thereinto for metabolic energy benefits. When the pool water W is free of chlorine, the vibrational energy of the pool water can be elevated easily by the low frequency wave. However, if there is presence of residual chlorine in the water, the initial vibration energy of water would be depressed by the chlorine in the water resulting in a longer treatment time to elevate the water entropy energy.

Nevertheless, to reduce the initial treatment time, residual chlorine in the water may be first removed by either heating, aeration or spraying.

A method aspect 10’ for water disinfection and/or energization, especially for the pool P or pool water system P’ comprises the following active steps, to wit: (1) disinfecting the pool water W mainly electromagnetically by emitting low frequency electromagnetic wave to the pool water W entering the pool P at preferred frequency range of 10% - 108 Hz, and more preferably 10 - 105 Hz, said step being preferably in combination with the substeps of: (a) filtering first the entering pool water W, preferably by using water filter(s) or filtering device(s) 13a such as sand filter, cyclone separator, other suitable fine mesh filters, or any combinations thereof; and/or (b) UV-treating the entering pool water W for combinably effecting water disinfection with immediate and long residual synergy disinfecting effects, thereby making the water substantially, if not completely, free from contaminants especially algae and bacterial/micro-organisms; and/or

(2) entropically energizing the pool water W by at least one entropy- inducing water energizer 11 preferably using emitted low frequency electromagnetic wave ranging from 102 — 10° Hz, and being provided to the system 10 at a strategic location and/or position for effecting water energization, thereby introducing metabolic entropy energy into the pool water W that retains and stores therein the energy resulting in an entropically energized pool water W whose metabolic entropy energy is capable of being transmitted to pool user(s).

More preferably, there is provided a further step (3) of transmitting the metabolic entropy energy to pool user(s) by the transmitting means 14 in preferred forms described above in the system 10, including the preferred pressurized spraying that adapts various the types of spray/dissipation nozzles 14a. There is also provided a water cleansing step (4) by using the water activator for skin cleansing 15 that is likewise described in detail above.

Optionally, there is further provided a water heating substep (c) preferably after the filtering substep (a).

SYSTEM AND METHOD FOR WATER DISINFECTION AND/OR

ENERGIZATION, ESPECIALLY FOR POOL WATER SYSTEM

FIELD OF THE INVENTION

The invention generally relates to water treatment, and more particularly to a method and system for water disinfection and energization, especially for pool water system.

BACKGROUND OF THE INVENTION

It is well known in the art to which this invention appertains that there are metabolic benefits obtained by user(s) in using pools or pool water systems.

The term “pool” or “pool water system” is defined in the succeeding detailed description to generally mean any water system or facility, natural or manmade, that is used for recreational or instructional purposes/activities such as swimming pool, natatorium, lido, swimming bath, bath, jacuzzi, sauna, bathtub, spa, wading/diving/sliding water facilities, or manmade or natural water catchment such as ponds, water way or seafront, and other recreational, sporting or instructional pool water facilities. Broadly, such pools or pool water systems can be classified as unheated-room-temperature pools, or heated pools.

Unheated pools are in general using the pool water to let the users engage in physical or exercising activities while inside or within the vicinity of the pools. It is through these activities that the users promote and rouse up the metabolic activities in their bodies which translate into health benefits. The unheated pool water by itself does not cause or give rise to any beneficial metabolic activities in the users’ bodies. On the other hand, heated pools which are in general found in spas, wading pools, jacuzzis, therapeutic bath, hot steam bath, hot spring water bath, and other pools of similar nature, have metabolic health benefits. The reason for this is that the heat energy in the pool water is transmitted to the users’ bodies, thus, aiding or stimulating the users’ body metabolism. Hence, the users need not get indulge in any physical or

. y exercising activities while in the heated pool to obtain health benefits from bodily assimilation of metabolic energy.

In human body metabolism, there are catabolic and anabolic metabolic processes. In the catabolic process, ATP (adenosine triphosphate) energy is produced from food intake. Such ATP energy provides the energy needed by the body cellular works, and the energy for the anabolic process to reassemble the basic biomolecules into new cells for building muscles, skin, tissues etc.

However, beside food intake, heat energy can also be used to supplement the metabolic energy. The pool water heat energy is able to provide supplementary metabolic energy to the user's body that is not engaged in any physical or exercising activities inside the heated pool. With the improved metabolic process, chemical reaction in the user's brain triggers the production of endorphins in his/her blood, letting him/her to feel good that is translated into feeling of muscle or pain/stress relief. Hence, users in the heated pool feel good and relieved from body pain/stress or the metabolic energy benefits just like what they feel or benefit after having physical or exercising activities in the unheated pools.

Further, when our body is immersed in the pool water, water itself is a good solvent and cleansing agent. It helps to clean our skin and clear our pores. As a result, the skin “breaths” better, giving us that same soft clean feeling after taking a shower or bath. In addition to the cleansing benefits of water itself, heat is in essence the energy that produces all such metabolic beneficial effects mentioned above. Notwithstanding these benefits, heated water from the pool such as in hot water spa/bath also constitutes health risks to users who have cardiovascular/diabetic disease or male fertility dysfunction, etc. In fact, our body is kept at a narrow constant temperature range to ensure all the body metabolic activities can be carried out at a most efficacious manner. Once the heat from water elevates the body temperature and exceeds the body constant and safe temperature range, instead of benefiting from the good supplementary energy metabolism enhancing effect, it actually upsets the metabolic process in our body and causing life endangering negative side effects such as nauseating, fainting, strokes, etc.

Irrespective of being heated or unheated, pools are using uncirculated or recirculated pool water. When such pool water is commonly shared and repeatedly by many users, bacteria and disease-causing micro-organisms would likely contaminate the pool water, posing health risks to the users. This is the main reason why existing pool or pool water system is provided with recirculating water systems with side stream filtration and disinfection mechanisms/systems that are commonly available in the market in varying sizes and capacities. For home-use small spas, hot water bath, etc. in which no circulation system is provided, the water is directly disinfected periodically by bleach or chlorination.

While hot water or room temperature water would provide recreational or metabolic benefits to the users, water hygiene is always a health risk that should not be taken for granted by the users. Hot water spa in particular, typically operates at the temperature range of 35 - 39° C which is an ideal temperature range for legionella and other bacteria to flourish. Legionella bacteria when inhaled into the lung can cause pneumonia. Disinfection is therefore critical to ensure effective bacterial control.

Normally, the water in existing pools is disinfected by chemical means such as chlorine, chlorinated isocyanurate, bromine or copper/silver ionization.

Ideally, these chemical disinfectants have good disinfection efficacy and with long residual time but it has many drawbacks. For example, chlorination is most commonly used due to its low cost and long residual disinfection effect.

However, chlorination and other chemically based disinfection have many common drawbacks and/or undesirable side effects to the users as follows, to wit: ered eyes, itchy skin, brittle hair, irritating smell, contraction of carcinogenic trihalomethane when reacted with UV, corrosion to respiratory system, ineffectiveness in penetrating biofilm to control legionella bacteria, bacteria immunity issue, ineffectiveness against cryptosporidium and other health risks; e bromine and chlorinated isocyanurate work in the same oxidizing principle as that of chlorination except bromine does not have the distinctive

. ‘ chlorine smell and both are not easily detectable as chlorine, but excessive dosage of such chemicals pose the same negative issues as chlorination; and e copper/silver ionization works by discharging copper and silver ions into the water for disinfection, and it has acceptable disinfection and residual effects, but it creates secondary pollution such that in some countries, silver is considered as heavy metal and is banned from being used in potable water.

Moreover, physical disinfection treatment using UV (ultraviolet) which is currently available in the market is unsuitable for pool disinfection although it can be used in conjunction with chlorination or chemical method. This is due to the fact that UV is effective only at the point of treatment, and lacks residual disinfection effect.

As regards algae bloom in pools, it is another common and major issue especially in places where pools are exposed to sunlight. While many algae species are not normally toxic, dead algae, which have foul smell, are capable of releasing toxic microcystins. Aside from that, algae are good breeding habitat for bacteria and other unwanted organisms or micro-organisms, and can degrade the chlorination disinfection performance.

The commonly known algae control method is using the same chlorination process, but its effectiveness requires high dosage of chlorine which poses high health risk to users. Though it can be used in shock dose or under super chlorination process, there is still a disadvantage in that the pool has to be put out of use for days. Copper sulfates and other algaecides sometimes are added to compliment the chlorination, but they are often toxic to pool users, and immunity to these algaecides is likely to become another issue that has to be addressed.

Further, it is well known in the art and industry to which the invention appertains that chlorination and other chemical disinfectants work well at certain pH range. For example, chlorination works in the pH range of 7.2 to 8.0.

If the pool water pH is higher than 8.0, higher residual chlorine concentration needs to be maintained to compensate for the degradation of disinfection effect

. ‘ of chlorine at higher pH. Hence, the pH and alkalinity level of the pool water need to be monitored and maintained at certain pH range for good disinfection performance. Unless the pool facility is maintained by competent personnel and/or experts, it is always a challenge for a layman to understand such chemistry or to maintain the water system chemistry.

There are other types or methods of chlorine-free pool water disinfection that are claimed to be chemical-free, but they are not in actual practice as they utilize chemically based processes or materials such as copper-silver ionization, ozone breakdown into oxygen, among others. For example, in PH Registration No. 2/2016/000112, ozone and copper-silver ionization for disinfection are used. These are actually chemical-based systems/methods for disinfection since ozone is unstable and it breaks down into radical oxygen as a disinfectant. Oz = O, + [O] (radical oxygen), hence, it is a chemical system. In the copper-silver ionization method, it is an electrochemical process of using electricity to generate copper and silver ions which are also chemicals in the water. Hence, copper-silver ionization is likewise a chemical system although no chlorine is used or external chemical is introduced. It is an in situ chemical generation. It is chlorine free, but not chemical free.

There are non-chemical treatments, such as the use of electromagnetic frequencies, applied to water or other liquids contained in containers such as boilers, industrial tanks, etc., but they are used only to remove, prevent or control the occurrences of unwanted matters in forms of rust and scale on the containers’ surfaces. For instance, US Patent No. 4865748 discloses a method/system for treating the water-containing container to remove and control rust and scale on its surfaces. It first sends out a wide range of variable frequency (not time-varying frequency) into the water system as a signal to see how the water and the container are responding to the signal frequency. With the feedback response, it then sends out another fixed frequency wave to treat the container. In a similar manner, there is also US Patent No. 7887708 that is intended for industrial cooling water scale and rust treatment purposes. Its disinfection aspect involves the use of copper silver ionization processes.
