Definitions
- the present invention relates to a system and a method for cleaning faecal-free and surfactant-containing household wastewater with an electrochemical treatment stage.
- toilet waste water is out of the question for the recycling of waste water, and flushing waste water is only of limited use.
- the shower water obtained could be cleaned and treated so that it could be used again as shower water. This would also make it possible for a relatively long time, for example 10 minutes, to be showered in a mobile home without the water being used up.
- the present invention has as its object that the surfactants contained in faecal-free household wastewater are removed as much as possible and thus purified water is obtained which is essentially free of surfactants and which in any case does not foam when it is used for showering or washing hands.
- the wastewater generated in a household should be recycled as well as possible in order to save water.
- wastewater is understood to mean wastewater from various sources, also referred to as consumers.
- the term not only includes the classic private household, but in particular also a mobile household, for example in a mobile home, caravan or on a boat or ship. Wastewater from aircraft and also from larger units such as hotels, cruise ships or entire residential complexes are also included. However, industrial wastewater, such as is produced in manufacturing companies, is excluded from the definition.
- the wastewater to be treated is free of faeces.
- H. Black water i.e. waste water from the toilet, is excluded. Typically, it will be waste water from the shower, the bathtub, from hand wash basins, from washing machines, i.e. gray water.
- wastewater from sinks and dishwashers can also be purified using the present invention, so that wastewater of this type is also included in the present definition. Wastewater from different consumers is thus treated, provided it is sewage free of faeces.
- Waste water from the shower and from the bathtub generally contains only a small amount of surfactant and also generally carries only a low amount of dirt.
- Waste water from the sink and the dishwasher is usually very surfactant and fat-containing and usually contains quite high pollution loads.
- Waste water from the washing machine and hand wash basin can, depending on the household concerned and the use of tensides and the dirt load to be washed off, be purified to practically pure clear water and accordingly z. B. be used as shower water or they are to be qualified as more polluted waste water and the purified clear water is z. B. only for flushing the toilet. As a result, an exact classification of a consumer's wastewater depends on the actual circumstances.
- faecal-free and surfactant-containing household wastewater is converted into germ-free and odor-free clear water, which is largely free of washing-active substances. Since it can then be used again for showering, for example, This results in the advantage that sufficient clean water is available for each person to shower, an advantage that is particularly beneficial for mobile homes, caravans and yachts, but also in hotels and cruise ships.
- the total amount of water to be transported is reduced by the present invention. Since a larger part of the water is in circulation and is reprocessed, both the amount of fresh water and the amount of waste water can be reduced.
- the fresh water tank and waste water tank in mobile units can be dimensioned correspondingly smaller and / or the downtimes can be kept longer without the annoying refilling of the fresh water tank and / or emptying of the waste water tank.
- the water in the system can be optimally used and reused. Heavily soiled and tenside-contaminated water can be used to flush the toilet, and only very little soiled and tenside-contaminated water can be used for showering, washing hands or washing up. In this way, the fresh water consumption in a household can be greatly reduced.
- the system and the method can be operated in circulation, quasi "online", i. H. while a person is showering, his / her shower water is processed, which is then immediately returned to the shower.
- a small amount of shower water e.g. B. with 10 liters of water
- a basically "infinite" shower time can be provided.
- the water is stored in a clear water tank after treatment and is then used in the next shower process.
- the dirty water of this next shower process is collected in a dirty water container until the end of the shower process and then or at any time, e.g. B. at night, processed and returned to the clear water tank. "Infinite" shower times are of course not possible in this way.
- the invention can also be used in stationary households, such as private households, residential complexes and hotels, and is advantageous. In many parts of the world and also in Europe, more groundwater is used than is reproduced, so it would be very desirable if wastewater was recycled in large quantities.
- waste water from the hand wash basin, the sink and the dishwasher is more polluted and often also contains a lot more surfactant than shower or bath water and possibly washing machine waste water.
- This wastewater is therefore kept separate and cleaned separately, because shower and bath water can be treated more easily and thus be treated to a higher purity than the wastewater from the sink, etc.
- different wastewater originating from different consumers, can be processed Depending on their degree of soiling and their type of soiling, store them separately, clean them separately and reuse them separately, with the greatest possible flexibility.
- more than two dirty water and / or more than two clear water tanks can also be provided.
- there are three types of dirty water tanks one for dirty water from the showers, a second for dirty water from the sink and a third for dirty water from the hand wash basin and washing machines.
- the waste water in the third dirty water tank dirty water from the hand wash basin
- the clear water created after going through the cleaning stages can be led to the shower in the shower water clear water tank or in the toilet flushing water clear water tank.
- bath and shower waste water is also collected after cleaning in a separate clear water container and, accordingly, the more polluted waste water from the sink, etc. after cleaning in another separate clear water container.
- Water from the second clear water tank, d. H. purified shower and bath water can then be used for showering and bathing again, whereas the clear water from the first clear water tank, i.e. H. purified hand washing water, dishwashing water and dishwasher waste water, on the other hand, is preferably used for flushing the toilet.
- the introduction of gas can, for example, with the aid of a compressor, a pump, a Stirring device or, particularly preferably with an aerator membrane, also referred to as aeration membrane, in particular with a ceramic aerator membrane. It turned out that it is particularly advantageous if the gas is as fine-bubble as possible in order to provide the largest possible surface. Fine-bubble gas bubbles generated with ceramic aerator membranes have a diameter of approx. 50-100 pm, for example.
- a further improvement in the removal of surfactant results from the fact that, in a preferred embodiment, a calming zone or several calming zones exist within or immediately after the electrochemical treatment unit, in which the purified water can calm down to the extent that it can be discharged.
- a calming zone or several calming zones exist within or immediately after the electrochemical treatment unit, in which the purified water can calm down to the extent that it can be discharged.
- the calming zone is correspondingly arranged in the bottom area of the electroflotation system and separated by a bulkhead.
- the separated, i.e. H. floated foam which is loaded with surfactants, possibly existing pollutants and dirt particles, is treated as waste water and fed to a waste water tank or discarded immediately.
- surfactants possibly existing pollutants and dirt particles
- the foam Before being discharged into the waste water tank, the foam can be destroyed in order to reduce the volume.
- the foam can be destroyed, for example, by sonication, by chemical anti-foam agents, by mechanical methods, such as passing through a foam-destroying fabric or sieve, by raining or showering down with an appropriate liquid.
- This foam destruction system is preferably installed in the overflow line.
- pretreatment and post-treatment stages can be added, such as different filter stages.
- both a pre-treatment by a pre-filter or coarse filter as well an aftertreatment can be carried out by a postfilter.
- the pre-filter or coarse filter mainly filters out coarser particles
- the post-filter is usually used to separate any fine particles that are still present. Accordingly, sand filters, microfiltration, nanofiltration, ultrafiltration and reverse osmosis are preferably used as aftertreatment filter units.
- pre-filter and coarse filter come z. B. Sieves and fabrics into consideration.
- the clear water generated by the method according to the invention or the system according to the invention can in one embodiment also be used to backwash the filter systems.
- the fresh water tank i.e. H. the container in which water from municipal water supply systems is bunkered is kept relatively small.
- a lack of water in the clear water tank can be detected by a sensor system, so that, for example via an electronic control, a subsequent washing process in the hand wash basin in the washroom can be extended until this lack of water is remedied. More waste water, and thus clear water, is deliberately produced by increasing the consumption of fresh water.
- a gray water reservoir and the electroflotation device can be connected to one another on the bottom side according to the principle of the communicating tubes.
- the electroflotation device and the filtration stage are connected on the surface side according to the overflow principle.
- the polluted water flows from the dirty water tank to the cleaning system, i.e. in the pre-filter, if available, or directly in the electro flotation stage.
- the layer thickness of the foam produced and drawn off, ie the floated can be carried out, for example, by an optical measurement, for example in the form of a light barrier or in the form of an ultrasound measurement.
- an optical measurement for example in the form of a light barrier or in the form of an ultrasound measurement.
- the fill level of the liquid container - dirty water container, clear water container, fresh water container, waste water container - is preferably monitored, e.g. B. via a float or another level sensor. So z. B. when a filling maximum is reached in the clear water tank for feeding into the shower, a float valve is opened by a corresponding floating float, the excess liquid either being transferred to a clear water tank, more precisely the one for flushing the toilet, or being fed to the waste water tank.
- Figure 1 shows a first embodiment of a household waste water recycling system according to the invention
- Figure 2 shows a second embodiment of a household waste water recycling system according to the invention.
- FIG. 1 shows a wastewater treatment system that could be implemented, for example, in a motor home or a yacht.
- the dirty water tank 21 is supplied with waste water from a wash basin 15 and a sink 13.
- the dirty water from both dirty water tanks 1 and 21 can be fed to a pre-filter 2.
- the waste water from the two dirty water tanks 1 and 21 can be fed together to the prefilter 2 or can be kept separately and passed separately through the cleaning stages. Coarse dirt particles and other coarser substances in the waste water, such as e.g. B. hair separated.
- the chemical metering unit is identified by the reference number 19.
- the electrochemical treatment unit 3 is equipped with plate electrodes 16.
- the plate electrodes are aligned parallel to each other.
- gas is introduced in fine-bubble form via an aeration membrane 14.
- ozone from an ozone ventilation 11 can be used as the gas.
- Ozone is a strong oxidizing agent, so any germs it contains can be killed. It also z. B. oxidized iron, manganese and organic matter.
- air can be used as the gas for introducing gas, designated by reference number 12.
- the unit for introducing gas is arranged inside the electrochemical treatment unit 3, namely the ventilation membrane 14.
- the air is introduced in fine bubbles.
- Foam is produced in the electrochemical treatment unit 3, both by the electroflotation itself and by the fine gas bubbles, as indicated in FIG. 1.
- the foam is compressed via a foam compression 17 and discharged via an overflow line 7 and fed to a waste water tank 9.
- a calming zone 18 is also entered in FIG. 1, in which the water is collected before being discharged from the electrochemical treatment unit 3 and can calm down, so that any gas still contained escapes and foam rises.
- the calming zone 18 is separated from the rest of the interior of the electrochemical treatment unit 3 by a bulkhead. Water therefore enters this calming zone 18 from below, very close to the bottom of the electrochemical treatment unit 3.
- An automatic level increase 27 serves to improve the foam discharge.
- Fine filter 4 for example a sand filter or a microfiltration unit, and an activated carbon filter 5.
- the cleaned water is fed to one of the two clear water tanks or both, namely the clear water tank 6 or the toilet clear water tank 22.
- the shower 25 is fed or else also a separate tap 23 of the sink 13, for example for pre-cleaning dishes.
- Water from the toilet clear water tank 22 is supplied to the toilet flush 24 using a pressure cylinder 10.
- the two dirty water tanks 1 and 21 and the two clear water tanks 6 and 22 can be treated separately.
- the dirty water from the dirty shower water tank 1 can be passed through the cleaning stages and fed to the clear water tank 6 or the toilet clear water tank 22. The same applies to waste water from the second dirty water tank 22.
- 20 fresh water can be used directly from a fresh water tank, for example also for showering or rinsing.
- the clear water tanks 6 and 22 can be filled with fresh water from the fresh water tank 20 if necessary.
- Filter systems can preferably be backwashed in order to remove residues adhering to the filtration process and thus to restore the filtration line.
- a backwash line 8 is provided so that treated clear water can be used for backwashing, for example for backwashing the activated carbon filter 5.
- fresh water from the fresh water tank 20 can also be backwashed.
- Foam from the overflow line 7 is collected in the waste water tank 9.
- waste water collected in the waste water tank 21, i.e. H. Sink wastewater and hand wash basin wastewater can be transferred directly to the wastewater tank 9 if, for example, temporarily heavy dirt loads are contained.
- a shower process is in two parts. First, water is showered from the clear water tank 6, i. H. the body is moistened. After soaping, the soap is still rinsed off with water from the clear water tank 6 and finally rinsed with fresh water from the fresh water tank 22.
- the toilet flush 24 preferably has fine nozzles. It is supplied with clear water from the toilet clear water 22 with the aid of a pressure cylinder 10, in particular with a High pressure cylinder or with a water pump.
- the electrochemical treatment unit 3 comprises a reversible DC voltage source. This can be reversed in a time-controlled or condition-controlled manner in order to prevent hydroxides from attaching to the electrodes 16.
- a polarity reversal also serves to ensure uniform wear of the electrodes 16, that is to say of the anodes and cathodes.
- the electrochemical treatment unit 3 is encapsulated in the upper area, i. H. provided with a cover 26.
- the electroflotation stage can also comprise oxidizing agents by means of which free hydrogen molecules are oxidized to water within the wastewater treatment. It is also possible to convert the hydrogen liberated to atmospheric oxygen to water via a catalytic converter, the atmospheric oxygen being ventilated, e.g. B. reaches the system via the overflow line.
- dirty water tanks There are two dirty water tanks - a first dirty water tank 121, in which waste water from a wash basin 115 and a sink 113 is collected, and a second dirty water tank 101, also called shower dirty water tank, in which waste water from the shower 125 is collected.
- waste water tank 109 in which the waste water to be discarded is collected, e.g. B. toilet waste water. Waste water from the first dirty water tank 121 can be cleaned as well as discarded. In the latter case, it is fed to the waste water tank 109.
- Waste water to be cleaned e.g. B. from the second dirty water tank 101, is first passed through a coarse filter 130. Coarse contaminants such as sand or hair are removed there. It then arrives with the aid of a pump P1 in the electrochemical treatment unit 103, where the electroflotation is carried out.
- the pump P1 is arranged in a container 131.
- the dirty water is temporarily stored therein and from there it is pumped to the first of the two tubular electrochemical treatment units 103.
- the container 131 has a buffer function. If the system is switched off, too much dirty water arrives or the system does not perform well enough, this buffer overflows and it goes directly into the waste water tank 109 without treatment. B. Incidents on the system can be ensured that showering can continue without interference.
- tube assemblies are used as electrochemical treatment units 103, each of which is covered with a cover 126.
- Tubular electrodes 116 have the advantage that they have a smaller footprint compared to plate electrodes with the same reaction area - an advantage which is v. a. in mobile homes, caravans, airplanes or yachts.
- two tube units are connected in series.
- the wastewater to be treated arrives in a relaxation tank 128, where relaxation flotation is carried out.
- gas is introduced via a ventilation membrane 114.
- both ozone can be introduced via an ozone ventilation 11 1 and air via a unit for introducing air 1 12.
- Ozone and air can be introduced separately or in combination. Which gas is to be used depends on the wastewater to be purified and the person skilled in the art can easily determine by simple experiments.
- Chemicals can also be metered into the flash tank using the chemical metering unit 119, if necessary.
- the separated part of the cleaned dirty water then reaches the waste water tank 109.
- the cleaned water which is drawn off in the lower region of the expansion tank 128, is finally led over three filter systems in the present embodiment, where the water is further purified.
- the individual filter stages are becoming increasingly fine. First, the water cleaned in the two flotation stages passes into a pre-filter 102, then into an activated carbon filter 105 and finally into a fine filter 104.
- the water which has been thoroughly cleaned in the two flotation stages can also be discharged by pumping it into the waste water tank 109 via a corresponding valve, in this case V2, with the aid of a pump P2.
- the clear water that has gone through all the cleaning stages is either fed to the toilet clear water tank 122 after the last cleaning stage or is fed directly to the shower system - either by bunkering it in a clear water tank 106 or by feeding it directly to the shower 125.
- Appropriate valves V7, V3, V4 and V5 ensure the desired supply line.
- Water bunkered in the toilet clear water tank 122 is used to flush the toilet 124.
- a pressure cylinder 110 is provided in mobile systems, which sprays the water in the toilet 124 in a water-saving manner.
- a fresh water tank 120 is also provided. If there is not enough recycled clear water available or e.g. B. at the end of a shower process, the shower 125 fresh water can be supplied from the fresh water tank 120.
- fresh water from the fresh water tank 120 or clear water from the clear water tank 106 can be used to backwash the system, in particular the three filter stages 102, 104 and 105.
- waste water from hand wash basin 115 and sink basin 13 is stored in the waste water tank 121.
- the clear water formed is typically stored in the toilet clear water tank 122 and used to flush the toilet 124. Waste water from the sink and hand basin may not be completely clean even after going through all the cleaning steps, making it unsuitable for showering or bathing. The same applies, for example, to waste water from the dishwasher.
- waste water from the shower collected in the waste water tank 101. These can be cleaned up so well because they are relatively lightly soiled that they can then be used again for showering.
- shower waste water which has passed through the system is collected in the clear water tank 106 and then returned to the shower 125 or the shower 125 is fed directly.
- bathing water which is generally only very slightly contaminated.
- valves and pumps are also entered in the schematic representation and are designated accordingly as P1, P2 etc. and V1, V2 etc.
- sea or river water can be sucked in and can be led through the wastewater treatment.
- another separate waste water tank would be provided for this.
- Rainwater can also be treated in this way and used as process water, for example for showering or flushing the toilet.
