Invention field

The present invention relates to a kind of purifier.Especially, the present invention relates to have the net of filter membrane and upstream sewage cistern Water installations.

Background of invention

There is problems with the portable purifier with the continuous antibacterial resin for arranging and closed membrane filter：Air will Be present between resin and thin film, current can be so hindered normal through the system.For this purpose, the water cleaning systems with exhaustor are Jing is developed, path of the exhaustor there is provided the space between resin and thin film to air.

United States Patent (USP) 6454941 discloses the example of a gravity filter, the gravity filter on thin film every Between in have resin, define the honeycomb texture of vertical direction.Space of the exhaustor between resin and filter membrane extends upwardly to Resin upper limb below water inlet.Water in device will not flow to exhaust outlet always due to mistake, because water outlet Gooseneck there is the outlet of its own, the outlet is located at below exhaust outlet, and water can be flowed out from the gooseneck first.

United States Patent (USP) 6638426 discloses the example of another gravity filter with exhaustor, and the exhaustor is arranged On filter, the filter has vertically disposed hollow membrane fiber.Resin of the exhaustor from center through top Chamber, extends to above the top water inlet on resin.The exhaustor is stretched out from lower tangential diverter, and the allotter is Reverse funnel.Diverter has hole, and water is downward through the hole from resin, enters the housing with filter.

These systems disclose the device in the space on emptying thin film.Other have the water cleaning systems of exhaustor also public Open, wherein exhaustor is extended on the horizontal plane of sewage cistern through the sewage cistern on top.United States Patent (USP) 4749484, United States Patent (USP) 4978449, United States Patent (USP) 4759474 are given in United States Patent (USP) 4800018, and European patent 404573 Example is gone out.British patent 1112072, United States Patent (USP) 3709362, European patent 245585, disclosed in United States Patent (USP) 5281309 Optional system, the system have exhaustor in the outside of sewage cistern.More gas extraction system are in Deutsche Bundespatent 3828008, United States Patent (USP) 3281108, United States Patent (USP) 6159363 are disclosed in United States Patent (USP) 7276169.Such as above-mentioned patent institute Show, portable system has the exhaustor through top sewage cistern, but for fixed system, exhaustor allows air from mistake The upstream side of filter media is discharged, and the exhaustor can run through the sewage cistern on top or in the outer of top sewage cistern Portion extends.Therefore, portable system seems to there are system limitations in terms of this, and this is to need compact knot due to these equipment Structure, although it means that for the feasible design of portable water treatment plant has some restrictions.

International patent application 2008/110166 discloses a kind of screening system of weight-driven in the figure 7, and the system has By managing the top sewage cistern being connected with filter element.In use, the filter element vertically, carrys out inherent filtration list The air of unit to upstream, is countered to the sewage stream from sewage cistern, is entered in sewage water reservoir by pipe.In practice In, this has no problem, although for startup, for the gas of emptier as early as possible, opening forward that water flow valve is more It is convenient.

If the system disclosed in 2008/110166 Fig. 7 of international monopoly, its filter element is that horizontally toward, air will Can be trapped in filter element, this is also the reason for module is vertically oriented when in use.Even however, in level side To, during from backward end injection sewage, by open forward water flow valve being still possible for system exhaust.Once gas Its exterior is rushed out, the water flow valve will be closed again.What air was exhausted from system is masked as outlet of the water in water flow valve Place occurs.Therefore, substantially, in the horizontal direction during correct running, there is no air trapping in equipment running yet.

By using water flow valve forward, system exhaust disclosed in international monopoly 2008/110166 is relatively easy, thus, such as Fruit space and compactedness are critical problems, then the defecator of such a horizontal direction is applied in other filtration systems Middle can quite attract.If however, such a system is not correctly understood by terminal user that problem is occurred as soon as .For example, for the user for being unfamiliar with the system, air discharge process may not substantially, and user may be only because empty Gas is stranded to prevent current normally to flow out from pure water inlet valve in systems, and thinks that the system is not normally run.And And, water flow valve may be erroneously interpreted as water purification source forward, and user might have risk using not having from sewage cistern There is the sewage through filter membrane.These risks are imaginary at first glance seemingly；It must be noted, however, that this filtration system is for answering Anxious area, busy action is sometimes associated with, due to the shortage of resource or time, not necessarily user may suitably be instructed Practice.In this case, the risk of error is very high and fatal consequence may be caused to user.

Said system there is also an issue, that is, do not provide suitable water purification collection device, it means that backflow pollution Very risky, particularly in case of emergency, now water purification lacks very much, and in terms of not focusing on health.

It is a kind of to issue on the internet for portable water purification systems in emergency circumstances,http:// espwaterproducts.com/emergency-preparedness-water-disaster-relief.htm.The system Including a top sewage cistern covered by prefilter, the prefilter is for removing residue and big heavy when adding water Starch granule.Sewage cistern comes eliminating bacteria and virus comprising iodine tablet.Inside sewage cistern, one vertically disposed heavy Starch prefilter is used for the dirt for removing as little as 0.5 micron of size, including capsule spore.The lid of clear water tank includes filter The outlet of sediment filter is directly connected by adapter, the adapter with vertically disposed multimedia filter cylinder, and the filter cylinder is used for Remove industrial or agricultural pollutant, chlorine, iodine and abnormal flavour.The multimedia filter cylinder is arranged in clear water tank, and is located under lid.Water purification Water tank is provided with faucet, for exporting water purification.

Because the lid of clear water tank is easy to remove, if lid is not correctly laid or is not fully being defended It is removed under conditions of life, the pollution of water purification readily becomes a problem.When in emergency, and in typical Africa In rural households, the latter is critically important, and animal and people mix and may be easily accessible to cleaning system and its periphery Environment.

As the system announced in United States Patent (USP) 6454941 and United States Patent (USP) 6638426, the system also has one to lack Point, that is, water filling in continuing upward swimming case can cause the overflow of any downstream part.Therefore, in order to not waste water, user must The water yield of the water yield opposite downstream part in the water tank of palpus recording filter upstream.What the latter lacked in the water yield is in emergency circumstances one Individual important problem.

Therefore, in order to improve portable water purification systems so as to higher safety and user friendly, particularly exist In terms of portable filter for emergency, researcher is continuously made great efforts always.

The content of the invention

It is an object of the invention to provide the improvement in the art.Especially, its object is to optimize user friendly, And will be minimized using the accident risk during device.Be partially improved is with regard to transporting and storing summary.It is other to improve It is with regard to air trapping is prevented in the case where intervening without using person in filter element, even in defecator horizontal direction In the case of setting.

The device includes the sewage cistern for accumulation sewage, and for the clear water tank of accumulation water purification, and purification is single Unit, such as filter element, for water of the purification in sewage cistern.Clean unit includes the filter of built-in purifying medium Housing, downstream of the purification medium by the upstream side of clean unit with clean unit are separated, so as to enter only from upstream effluent The water for changing unit can only flow into downstream by purification medium, such as many microporous filter membrane.Upstream side is connected to sewage cistern, For receiving the sewage into upstream side, downstream is connected to clear water tank, for the water for having filtered is exported to from downstream In clear water tank.Alternatively, clean unit is placed in the outside of clear water tank.Sewage cistern is arranged on the upper of clean unit Face, is driven by action of gravity and passes water through clean unit.Sewage cistern has outlet, and filter housings are upper with leading to The upstream entrance of trip side, wherein cistern outlet and upstream entrance are fluidly connected by first flow adapter, and this One flow connector receives the upstream side that sewage sends into clean unit from sewage cistern.The device includes clear water tank, should Water tank is fluidly coupled to downstream by lower exit, and the lower exit receives the water for having filtered from downstream.Alternatively, Clear water tank is arranged on below clean unit.

Purification medium has several to select, for example, the resin of different delivery of antimicrobials.The tree of chlorine or iodine is discharged for example Fat.Other media for selecting to be active carbon particle or other capture microorganisms and other microgranules.Tepper and Kaledin An example of this other absorbing mediuies is disclosed in United States Patent (USP) 6838005, fibre substrate therein includes positive electricity The adsorbable nanoparticle of property.In this case, alumina nano fiber is arranged in cellular glass fibre substrate, by attached The filtering microorganism on nanofiber.Microorganism and inorganic sediment is by high electropositive alumina adsorption and forever stops Stay, it is impossible to discharge from filter substrate.Purification medium is also likely to be the combination of several different medium, for example halide resin with Activated carbon is combined.

Or, clean unit is filter element, and purification medium includes microporous filter membrane.One of which preference is hollow fibre Dimension filter membrane, such as bundled hollow fiber filter membrane, although other kinds of microporous membrane can also be used.The filter element can be with One or more other above-mentioned medium is used in combination, and for example fibre substrate includes positive electricity adsorption of nanoparticles.

There is above-described purifier useful feature to combine.In addition, which advantageously forms further below Improved basis, for portable unit.

Exhaustor

One independent improvement is related to the simple aerofluxuss in filter element upstream side, is useful to this following examples. In this case, the upstream side of filter element has upstream outlet in filter housings, as the liquid from upstream side Outlet.Exhaustor is connected to upstream side exit；The exhaustor is upwardly extended, and preferably in the outside of clear water tank, and is had Exhaust port, for the air from upstream side is discharged in air.Alternatively, exhaustor prolongs on the side in the outer of clear water tank Stretch, although it can also extend on the inside of sewage cistern.

Water in sewage cistern will be press against upstream side by filter element and from filter element by gravity Upstream side is entered in exhaustor.By this action, air is by hydraulic pressure in exhaustor.Therefore, if exhaust port is set In the position higher than sewage cistern bottom, the air in exhaustor will be extruded to and the horizontal plane phase in sewage cistern Corresponding height.It is therefore assumed that when the horizontal plane in sewage cistern is higher than the height set by exhaust port, siphonic effect will Water can be caused to be forced out at aerofluxuss tube opening highly identical at the horizontal plane in water storage tank with aerofluxuss tube opening.In order to keep away Exempt to unnecessarily waste water, the bottom at the highly preferred top rather than sewage cistern to be close to sewage cistern of aerofluxuss tube opening Portion.Especially, the height of the opening should substantially be adjusted to the top level face or higher of sewage cistern.For example, aerofluxuss Tube opening is arranged on reference altitude, and the reference altitude is at most 5 centimetres or 2 centimetres of the upper limb less than sewage cistern, or even Only at most 1 centimetre, although steam vent can also be arranged on the upper limb of sewage cistern.

In the case where exhaustor is upwardly extended on the outside of sewage cistern, a kind of selection is in the outer of sewage cistern The top of side additional exhaust pipe.

Back scrubbing

One independent improvement is related to the safety of water purification unit back scrubbing.Therefore, in another embodiment, the device includes Backflushing system, the device are used for membrane filter in filter element.In this case, the device includes manual compressible Back scrubbing capsule, the back scrubbing capsule are fluidly coupled to downstream to collect water purification for back scrubbing, and the connection connects preferably by elastic hose Connect.

The principle of this back scrubbing facility is it is well known that for example by above-mentioned international monopoly 2008/110166.Term " capsule " It is generic term, including the specific embodiments of capsule such as balloon or bellows or other resiliently-compressible water chamber.Back scrubbing Pipe is set to for example have first end, and the end is connected to upstream side, for receiving getting dirty from filter element upstream side The backwash water of dye, and for example there is opposing end, the end is connected to backflushing vessel, holds into back scrubbing for conveying backwash water Device, when by compressing back scrubbing capsule, water is extruded into upstream side through thin film from downstream, and further passes through back from upstream side Wash pipe to enter in backflushing vessel.The risk for misapplying contaminated backwash water is reduced to minimum by the container.

Used as further option, the backflushing vessel is arranged below the level height of filter element, to guarantee to flow into back The flow for washing container is suitable.Further option is if backwash pipe is connected to back scrubbing appearance by the fluid intake of backflushing vessel Device, around many holes preventing from drinking from there at the fluid intake；This point improves user security.

In another embodiment, in order to prevent backwash water that sewage cistern, one way stop peturn valve are pressed in backwash process It is arranged between sewage cistern and the upstream side of filter element.

Alternatively, the improvement of above-mentioned back scrubbing is combined with independent exhaustor embodiment.In the case of this combination, root According to following examples, it is possible to further improved, the backwash pipe is exhaust pipe device part of the whole.Therefore, no Need to provide single backwash pipe and single exhaustor, and be to provide the single pipe with singulated dies to realize the two It is sufficient that purpose.Alternatively, united aerofluxuss backwash pipe has the downstream tube portion of exhaust port, and the tube portion is connected to back Wash container.

Thin film is maintained in water

Another independent improvement, alternatively, the improvement independently improves combination with above-mentioned one or more, and description is such as Under.In this embodiment, downstream is connected to clear water tank by lower exit, lower exit position when normal use is filtered On thin film.This prevents filter element from emptying so that thin film keeps being immersed in the water, for polymeric film such as hollow-fibre membrane For be very important because dehydration may cause disintegrating for membrane pores.For example, lower exit is arranged at filter housings Upper end, particularly in the case of filter element is inclined horizontally toward or from the horizontal by most 45 degree or 10 degree, under Swim out of mouth to be positioned above the height of film position in filter element to keep horizontal plane higher than the thin film in filter element.

Allotter

Another independent improvement, alternatively, the improvement with above-mentioned one or more independence is combined, and is described as follows. In this case, the improvement is related to allotter, for distributing the water from filter element downstream.In order to by water from filter element Downstream be delivered to clear water tank, the downstream of filter element is connected to clear water tank so that filtration water from filter element Downstream flow in clear water tank.In another embodiment, the connection is realized by allotter.The allotter includes Access road, for receiving the water for having filtered from the downstream of filter element, the first export distributor, for being filtered Water be delivered to back scrubbing capsule, and the second export distributor, for exporting filtered water to clear water tank.Preferably, this point Orchestration includes one way stop peturn valve, and the check-valves are arranged between the first export distributor and the second export distributor, due to compression Back scrubbing capsule, when water passes through the first export distributor by back pressure, the check-valves prevent the water for carrying out self-compressed back scrubbing capsule from entering Clear water tank.For example, the check-valves are ball valve.Such a valve can be arranged in the valve body comprising ball and ball seat, the ball Seat is arranged at adjacent fluids flow connector and exports on the valve casing body wall of side away from the second filter housings.

In another embodiment, the allotter also includes one-way exhaust valve, for entering in water tank from filter element in water When, discharge the air of the clear water tank of sealing.Due to the filling of Water in Water Tanks, and so that the air pressure in clear water tank is more than Atmospheric pressure, only the check valve allows air to leave clear water tank at this moment, therefore, the valve is only opened when there is outside air-flow Put, This prevents dust and microorganism enters clear water tank.However, in another embodiment as additional security measure, The valve can be arranged with air permeable film to prevent microorganism and dust from returning to clear water tank.In this case, alternatively, should Valve can be two-way valve, air so can be made when water is exported by faucet to enter clear water tank, so further can be dropped The risk of low backflow pollution.In another embodiment, in order to prevent the water in the case of clear water tanks spill-over from escaping by air bleeding valve, The air permeable film is to prevent hydrophobic membrane of the water by air bleeding valve.Or, in order to prevent the water in the case of clear water tanks spill-over from leading to Air bleeding valve effusion is crossed, the valve is may be configured as with waterstop, for example should to close in the case where clear water tank is full including ball valve Valve.

Transport

Another independent improvement, the improvement are alternatively independently improved with above-mentioned one or more and multiple embodiment phases With reference to being described as follows.In this case, the improvement is related to handling, storage and transport.These embodiments are single not only for purification Embodiment of the unit for filter element, and for the embodiment of various purification mediums has universality and practicality.

In order to protect filter element without damage when handling facilities, the clean unit is preferably arranged on water purification water In the inside of case, or the space between clear water tank and sewage cistern, that is to say, that the sewage storage on the clear water tank Under hydrophone.The structure of the latter gives the passage towards filter element, and for example, in the case of an exchange, this structure is relative Better than the structure that water purification unit is placed in the clear water tank of sealing.

Preferably, the space is determined that by the intermediate module with cross sectional dimensions the cross sectional dimensions are right in the horizontal plane Should be in sewage cistern and the cross sectional dimensions of clear water tank.For example, under laminated arrangement sewage cistern, intermediate module and net Water tank constitutes integrated three module system, and wherein intermediate module is supported by clear water tank, in turn, intermediate module supporting sewage Cistern.It is for ease of mounting and dismounting filter element, first-class between sewage cistern and filter element upstream side Body adapter is flexible pipe.

Some storages and transport particularly advantageous embodiment to equipment include following improvement.In these cases, equipment With the connection between clear water tank and sewage cistern, the connection include for change clear water tank and sewage cistern it Between distance device.The connector has first state, and wherein clear water tank and sewage cistern is in close proximity, and this is Storage and travel position, and the connector has the second state, wherein clear water tank and sewage cistern in away from shape State, this is the operating state of drainage.For example, in the second condition, the distance between clear water tank and sewage cistern ratio is in Between the distance of approximated position is big 5 centimetres to 100 centimetres.

This component is used to change distance, alternatively, including the outside or sewage water storage of one group of side plate and clear water tank The outside in the outside of case or both is slidably matched.For example, clear water tank has groove on the outside of which, for accommodating slip The side plate group of cooperation.Or, sewage cistern includes this groove.

In an optional embodiment, change distance instrument include rotatable hinged side, the side plate relative to Clear water tank has variable angle, and the angle depends on the distance between clear water tank and sewage cistern.For example, the side plate Clear water tank is articulated with first axle and sewage cistern is articulated with second hinge.Optionally, in addition, the sewage cistern With a upper opening, the size of the opening is more than the cross section of clear water tank so that clear water tank energy portion under storing state Enfeoffment loads in cistern.When the embodiment is combined with the above-mentioned exhaustor for improving, the exhaustor is preferably in sewage In cistern inner side upwardly extend, in case with other machine components tangle ups.

Each embodiment

Hereinafter, each embodiment can be combined with above-mentioned independent improvement.

The thin film for passing water through clean unit is driven in order to provide enough gravity, in another embodiment for the equipment In, sewage cistern is placed on clear water tank, apart from least 10 centimetres or 20 centimetres of clear water tank, and alternatively, extremely Many 40 centimetres or 30 centimetres.For example, sewage cistern is placed on clear water tank, between sewage cistern and clear water tank At least 5 centimetres or 10 centimetres or 20 centimetres of gap.The distance is shorter, and the pressure of clean unit corresponding to this is also low.

Particularly in the case where clean unit is the filter element with many micropore filtering films, low gravitation pressure has one Individual advantage, particulate matter are loose in the relative holding in inflow surface of thin film, so that backflow and cleaning become easy, and extend Life-span of membrane filter.

Due to the accumulation of clear water tank, can be with very little, because the equipment can be not required to make by the flow of clean unit User intervenes and carries out drainage in the case of monitoring.For example, sewage cistern dusk fill, the device can night at leisure Drainage is with one water tank for filling water of the next morning offer.Even if being filled in sewage cistern, clear water tank is not yet arranged In the case of sky, the water yield in sewage cistern is also what is had no problem more than the acceptable capacity of clear water tank, because water purification Water tank be sealing, once and clear water tank fill, drainage will stop.

For example, the equipment is that a size is easy to man portable portable equipment.For example, the portable equipment net weight is less than 30 Kilogram.Additionally, the capacity of sewage water storage tank is alternatively, it is less than 30 liters.Another additional option, the capacity of clear water tank are less than 30 Rise.However, the present invention is not limited to portable equipment and creative feature similarly can be applied on bigger equipment well, example Such as, as school, the hotel even water purification facilities of community.

Connection between sewage cistern and clean unit, or the connection between clean unit and clear water tank can be Hard tube, however, for ease of installation equipment and being easily installed and dismantling clean unit, it is soft that first flow adapter is preferably elasticity Pipe, although this is not required.Alternatively, exhaustor is also elastic tube.

Clear water tank can arrange openable outer housing during cleaning.In one alternate embodiment, reduce back to try one's best The risk of stream pollution, clear water tank is with the outer housing closed to environment." closed to environment " this term means in the outer housing On there is no the hole that can allow dirt or microorganism that clear water tank is directly entered from external environment." closed to environment " this term In view of be also effective when having faucet, the faucet is provided with drain valve so that water is exported from clear water tank by faucet, Because usually, the faucet is to close.In addition, in order to provide the connection of water purification to water purification unit, in clear water tank It is required with opening；Although in principle, having a connection, the connection is from clear water tank by purification/filter element Purification medium, such as thin film, and by the connection to sewage cistern, air is then discharged to, the connection is considered Sealing, because no dirt or microorganism can be entered in clear water tank by thin film.More openings, such as aerofluxuss can be set Valve, the air bleeding valve is to the atmosphere opening in environment；However, this opening is occurred only in such control mode, when water quilt When loading clear water tank or passing out, air flows out or possible inflow process.This valve is also generally to close , so as to prevent the entrance of dust and microorganism, here it is why this valve for clear water tank also not with it is " close to environment Closing " this term contradicts.Additionally, this valve may also include ventilative but fluid-tight microporous membrane, to prevent dust and micro- life Thing is open by these.

In order to protect the water in clear water tank not contaminated, may be configured as with sterilizing methods in the clear water tank.One Selection is that antibacterial is added in water, such as by powder or the solution by the solid chemicals containing antibacterial.Or remove Beyond this, clear water tank can include bactericidal agent on the wall of clear water tank or in wall.For example, inwall can arrange to have prevents micro- The antibacterial that biology is bred on clear water tank inwall.

An example with regard to providing antimicrobial surface is the coating of oiling antibiotic substance.A large amount of different coatings are available for making With.United States Patent (USP) No.6,762,172, No.6,632,805, No.6,469,120, No.6,120,587, No.5,959, Disclose in 014No.5,954,869, No.6,113,815, No.6,712,121, No.6,528,472 and No.4,282,366. The example of antimicrobial organosilane coating.

Another feasible program is containing silver-colored antimicrobial coating, such as collargol.Collargol is included and can be suspended in base Silver nano-grain (1 nanometer to 100 nanometers) in body.For example, silver sol can be for example boiled from the mineral with loose structure Disengage in stone.Silver can also be embedded in substrate, for example polymer surfaces film.Or, silver can be embedding in plastic forming operation Enter in the whole polymeric matrix of clear water tank, usually spray casting, extrusion molding or blowing.

Argentiferous ceramics disclosed in United States Patent (USP) No.6,924,325 (Qian) can be using in the invention.The U.S. is special Sharp No.6,827,874 (Souter et al.), No.6,551,609 (King) disclose the silver for water process, are improved with silver Granulated carbon for water purification is well-known.The silver coating for water tank is disclosed in European patent 1647527.

Other antibacterial metals that can be used in this invention have copper and zinc, may be selected or additionally can be incorporated to antibacterial In coating.Antimicrobial coating containing silver and other metals is in United States Patent (USP) No 4,906,466 (Edwards) and its list of references In be disclosed.

May be selected or can additionally, coating may include titanium dioxide.Titanium dioxide can serve as thin film, and the thin film is logical Cross sol-gel process to synthesize.Because anatase titanium dioxide is a kind of photocatalyst, titanium deoxid film outer surface exposes to the open air It is useful in ultraviolet and ambient light.And, titanium dioxide nano-crystal can be also embedded in polymer.Additionally, silver nanoparticle Granule can synthesize to improve effect with titanium dioxide.

For example, film coating can have several microns of thickness.Additionally or selectively, coating includes reactive silane season Ammoniate, can be from such asHouse mark is Microbe Shield^TMProduct for air adjustment is recognized.As When being used on material for liquid, the active material in the AEGIS antibacterial forms the positively charged thin polymer film of colorless and odorless, The thin film that this chemically solidifies can hardly be removed from processed surface.

More more options include quaternary ammonium coating, such as the polyethyleneimine coating with antimicrobial quaternary amines.

Some antibiotic substance can be migrated through polymeric matrix.This means that coating may be comprising antibiotic substance, this resists Fungus matter is continuously being updated due to migrating to coating surface from coat inside.Therefore, in another embodiment, water purification The material of water tank wall is by made by the material comprising antibiotic substance.The anti-biotic material is with the table from the inside of material to material The characteristic of face migration.

Depending on coating process, inwall sterilization face coat can also be realized by infiltrating.Similar spraying process can be with It is applied to each special surface.

One additional option that may be incorporated into clear water tank is a Burdick lamp, such as United States Patent (USP) No.2005/258108 As open.In addition to sterilizing means, such a lamp can be used.

It is different from and distributes antibacterial in clear water tank, or as the option of the distribution antibacterial in clear water tank, Clear water tank can have cistern to discharge the water purification in nutrient and/or medicine to clear water tank.For example, from clean unit Water purification flow into cistern and by dissolving in cistern slow solvable matrix being enriched with water.For example, the matrix includes medicament, The medicament is discharged according to the dissolving of substrate.A kind of feasible program is that the water-soluble glass comprising releasable medicament can be dissolved in Glass itself or the gap being dissolved between sintered glass bead.

The example of the membrane filter in one filter element is ceramic filter or semi-permeable polymer filter, is used In microfiltration or ultrafiltration.For example, filter element includes the clean unit with multiple hollow fiber microporous membranes, and alternatively, this is hollow Fibrous membrane be arranged in parallel and encloses the two ends of resin, or is bent and encloses one end.2008/110166 He of international monopoly 2008/110172 gives an example.Optionally, hollow-fibre membrane is with the outside towards upstream side and towards downstream Inner side；This is generally referred to as flow structure from outside to inside.Or, the hollow-fibre membrane is with the inner side towards upstream side and direction The outside in downstream." microporous " this term summarises microfiltration porous and ultrafiltration porous.

Preferably, membrane filtration units are used for virus and bacteria of the blockage size more than 0.2 micron and parasite.For example, parent The microorganism stratum disjunctum that water thin film is smaller in size than 0.2 micron with hole is used together.Alternatively, the filter element includes microporous membrane, Such as bundled hollow many microporous fibres, with thin film of the surface size between 0.05 square metre to 0.6 square metre, for example, exist Between 0.1 square metre to 0.3 square metre.

Used as an additional safety measure, another embodiment includes that additional filter or the purification in microporous membrane downstream are situated between Matter.One example with regard to the additional filter media includes the fibre substrate containing the absorbable nanoparticle of electropositive.This mistake It is disclosed in one example US patent US6838005 (Tepper and Kaledin) of filter medium.In this case, aoxidize Aluminum nanofiber is arranged in a cellular glass fibre substrate, by microorganism adsorption is micro- to filter on nanofiber It is biological.Microorganism and inorganic sediment are adsorbed and permanent stop by high electropositive aluminium oxide, will not be in filter substrate Release.Capacity of the life-span of filter depending on the pollutant level and filter contained in the water for flowing into.More this substrate It is described in international monopoly 2008110167.

For example, bundled doughnut microporous filter membrane is followed by the fibre substrate for adsorbing nano-particle comprising electropositive. The virus not prevented by micro-filtration hollow-fibre membrane will be captured by the substrate.Advantage is the relative hollow fibre with ultrafiltration ability Dimension, has higher flow velocity in the substrate.And, in film breaks or for the pouring material of thin film, to lose which hidden close In the case of envelope property, the substrate will capture microorganism and other granules；In view of the substrate is the extra safety of such a arranging Apply, the combination of bundled Hollow Fiber Ultrafiltration thin film and the subsequent nano-particle comprising electropositive absorption is also useful.Its His microporous membrane can also replace hollow fiber film in described filter element.It is public in international monopoly 2008/110166 Open microfilter and adsorb the combination of the fibre substrate of nano-particle comprising electropositive.

Material for capillary film preferably comprises polyether sulfone (PES), polyvinylpyrrolidone (PVP) and titanium dioxide The synthetic of zirconium (ZrO2).Such as European patent 241995 or described in international monopoly 2009/019592.

In another embodiment, clean unit, such as filter element, with filtrate housing, the housing is along longitudinal axis extension Tubulose, and along the direction of its longitudinal axis and the angle of horizontal plane at most 45 degree or 25 degree or 10 degree.For example, the purification/ Filter element has the longitudinal axis of level or level of approximation.

If the filter housings are the relatively small tubular filter housings of a size, just it is largely fulfilled The compactness of portable system clean unit, for example, is 100 millimeters of cross section to the maximum with circumscribed circle diameter.Clean unit is another One useful size is that length is less than 50 centimetres, e.g., less than 30 centimetres.

Select as one, sewage cistern potentially includes an antimicrobial source, such as halogen source.Comprising releasable chlorine Tablet, such as, by dissolving from a within the chamber comprising this kind of tablet, be a feasible selection, although there is other kinds Medicament dispenser can be used.Unconfined option be discharge liquid sterilant micro- allocating system, such as iodine or chlorine.Other Option includes discharging halogen biocide or the resin based on the biocide without halogen species.

Serial number in claim not limits the scope of claim.
