53CA1118365A1 34 REVERSE OSMOSIS METHOD AND APPARATUS KEEFER BOWIE Reverse osmosis, particularly for water desalination, is achieved using semipermeable membranes which selectively permeate purified water from a feed solution pressurized by reciprocating piston or diaphragm pump. Pump action is assisted by returning pressurized concentrate fluid acting on reverse side of the pump piston or diaphragm. Directional valves controlling alternating admission and venting of concentrate fluid to and from pump cylinder are actuated mechanically by reversal of force applied to the piston rod. Mechanical dwell is provided in the piston or diaphragm motion during directional valve actuation. Pump may be operated by a manual lever or by a crank mechanism on a low speed rotary shaft. An optional differential surge absorber provides continuity of feed solution circulation past membrane surfaces during the return pump stroke, thus minimizing detrimental salt concentration build-up on the membrane 1 1

65CA2132929A1 1 WATER DECONTAMINATION SYSTEM WITH DIMMER-CONTROLLED ULTRAVIOLET LAMP SZABO LOUIS An ultraviolet-based or dual mode water purifying system operates under household water pressure to provide a batch treatment of contaminated water. Treated water is stored in a pressurized reservoir, from which it may be released for use. A treatment cycle is initiated by a drop in pressure within the system, which occurs when sufficient water has been withdrawn from the reservoir. The pressure drop is detected by a pressure gauge linked to a UV lamp dimmer, which causes the UV lamp to change from a reduced-output standby mode to an operative mode. The dimmer may be further linked to a thermostatic switch positioned adjacent the lamp, to reduce the output of the lamp when the temperature exceeds a predetermined level, and to a backwash event control, to increase the lamp output to the operative level during filter backwash. The UV lamp may also be employed to generate ozone, which is reacted with the water in an ozone/water contactor upstream of the UV water exposure chamber, and that constitutes a helical tube with ozone being introduced to the fluid at the base of the tube and permitted to rise with the fluid through the tube. A filter may be provided between the contactor and the UV exposure chamber to remove suspended particle

70CA2186963C 8 HIGH WATER RECOVERY MEMBRANE PURIFICATION PROCESS AL-SAMADI RIAD A Disclosed is a two-stage high pressure high recovery process utilizing two rever se osmosis membrane systems intended to provide very high overall water recoveries from contaminated inorganic scale-containing water in an economical manner while preventing scale formation on the membrane and prolonging the useful life of the membrane. The first stage of the process involves using a low pressure membrane system to preconcentrate scale compounds while purifying the bulk volume of the scale-containing water (using antiscalants with pH control) and combining the in fluent water with a recycle stream of concentrate from the second stage membrane process in o rder to prevent scale formation. This first stage membrane system is followed by a secon d stage membrane system wherein the concentrate from the first stage membrane system is treated further at higher pressure in order to provide purification of the remai ning preconcentrated stream and achieve very high overall water recoveries. Scale for mation in the first stage and second stage membrane systems is prevented by the recycle of ""softened"" water containing a very low concentration of scale-forming compounds and containing a high concentration of soluble salts to both stages in a specific pr oportion that represents an economically viable process, while ensuring adequate permeate quality.

74CA2247386A1 1 MEMBRANE FILTER WITH ELECTRICAL AND/OR ACOUSTIC ENHANCEMENT ATKINS FULFORD LTD This invention relates to tubular and flat sheet membrane filters, particularly those filters whose ability to separate particulate, molecular or ionic contaminants from suspensions is enhanced by the addition of electric fields to the filter. When a membrane filter is in use, contaminants from the feed liquid accumulate at the membrane surface to form a polarised layer which inhibits flow through the membrane. Contaminants in a liquid become charged and when subjected to an electric field will migrate toward one or other of the electrodes. If the electrodes are located either side of a permeable membrane or barrier, the contaminant can be caused to migrate by electrophoresis away from the membrane or barrier. The system can be made more effective by using a combination of ultrasonic fields and controlled hydrodynamic fields with the electric field. The ultrasonic and the hydrodynamic fields will improve the separation of the solids from the water and the electric field will cause the particles to migrate away from the membran 1

89CA2381309A1 1 ON PREMISE WATER TREATMENT SYSTEM AND METHOD COCA COLA CO A water treatment method uses a removable, disposable cartridge (2) having a n internal mesh structure. A disposable heater (6) heats water fed to the cartridge. Precipitated solids collect on the mesh surface provided temperature and residence time are appropriately maintained. The heat breaks down the bicarbonate hardness of the water thereby depositing carbonates on the mesh surface and heavy metals will be codeposited due to the resultant change in pH. The cartridge has a head-space (11) for collecting entrained gases such as volatile organic compounds, chlorine and air. Water sterility is achieved by heating the water over an appropriate period of time. Turbidity is removed within the cartridge due to settling induced by the low fluid veloci ty controlled by a controller and by a filter provided at the outlet of the cartridge. The filter will become blocked when bicarbonate hardness is carri ed over forcing a user to replace a spent cartridge. Heat economy and a cool treated water outlet stream are secured by use of a heat exchanger (18). Wat er is fed from the cartridge, through an intercooler and the heat exchanger to a storage tank (26). Water in the storage tank is kept out of contact with air by a movable barrier.

128CA2644795A1 1 SYPHON FILTRATION SYSTEM KORZENIOWSKI JAN A A syphon filtration system is a low head, small foot print, long operating cycle, gravity filtration system for treatment of water and wastewater. The filtration system is an apparatus and process with one-stage or two-stage filtration process in one vessel. The filtration system can use different filtration media of sand, anthracite and activated carbon or other proprietary filtration media. The one-stage filtration system is applicable to removal of suspended solids or dissolved impurities. The two-stage filtration system can provide a combination of two different filtration processes for removal of suspended solids and dissolved impurities. The one-stage filtration system has low head room requirements, and the two-stage filtration system has small foot print requirements. In the two-stage filtration system, each filtration stage can be backwashed independently or both stages can be backwashed simultaneously. The filtration system uses novel syphon piping and controls design which extend the filtration operating cycle and reduce the filter apparatus headroom, and the filter backwash water volume requirement 1

1167CS216673B2 34 METHOD OF CLEANING THE CHLORINATED WATER IN THE SWIMMING POOL AND DEVICE FOR EXECUTING THE SAID METHOD KAAS SYSTEM TEKNIK APS H [From equivalent US4372860] By a method and an apparatus for cleaning water in a swimming pool, the water is circulated successively through a plurality of flow chambers divided by partitions. In the front chamber bar-shaped heating bodies are located transverse to the flow direction of the water, and in the succeeding chamber ultraviolet radiation lamps are located transverse to the flow direction, said lamps radiating light at lambda >300 nm. In a last chamber ultraviolet radiation lamps are located which radiate light at lambda <300 nm. When the water passes through the container, skin squames and the like organisms collect on the heating bodies, whereas the ultraviolet radiation lamps in the chamber ensure such a disinfection that only a quite small amount of fresh water need to be supplied to the swimming pool. The ultraviolet radiation lamps serve to kill the bacteria resistant to chlorine.

1227DE10200812A1 1 Dreiweg UV-Ultraschall Wasserreinigungsreaktor SOBNIN JURI Eine breite Anwendung bei der Wasser-Reinigung und -Desinfektion - ultraviolette Strahlung.
Diese Methode weist eine Reihe von Vorteilen auf, birgt aber auch einige Nachteile in sich:
1. Ungenügende Bestrahlung des aufzubereitenden Wassers.
2. Geringer Abbau organischer und anorganischer Verbindungen.
3. Nicht komplette Desinfektion.
4. Verschmutzung und Biobewuchs des Quarzstutzglases.
Eine Erhöhung der ultravioletten Dosis (Verweildauer des aufzubereitenden Wassers im Reaktor) wird erreicht durch eine Erweiterung der Reaktorkonstruktion um Trennwände, wodurch die Verweildauer des Wassers im Reaktor um das 3-fache ansteigt.
Im Angebotsreaktor werden zwei Verfahren kombiniert: die Bestrahlung mit ultravioletten Strahlen und die fokussierte Ultraschallbestrahlung.
Bei bestimmter Intensität und Frequenz des Ultraschalls im Strom des aufzubereitenden Wassers kommt es zu einer starken Erhöhung der Kavitation, der Temperatur und des Druckes. Dies erhöht die Effektivität der UV-Bestrahlung um das Hundertfache.
Eine intensive Kavitation führt zur vermehrten Bildung von Rissen im Wassermedium an Stellen mit Ungleichartigkeiten. Als Ungleichartigkeiten dienen Pilz- und Bakteriensporen, gelöste organische und anorganische Verbindungen, die sich beim Platzen eines Bläschens in seiner Mitte befinden und eine Art Zielscheibe bilden. Bei so einer verstärkten Kavitation wird die Zersetzung von organischen und anorganischen Verbindungen um das Mehrfache .

In comparison with previously known methods, a significant reduction in investment cost and operating cost can be achieved by the combination of the following measures: The water to be processed is kept in a supply chamber the wall of which is formed at least in part by a hydrophobic membrane being permeable for water vapor. A hydrophilic membrane having a greater thickness in comparison with the hydrophobic membrane and a lower thermal conductivity per unit area runs in parallel with the hydrophobic membrane.; By the pumping action a vapor pressure difference is produced between the water to be processed and the fresh water so that the membrane distillation is driven by the vapor pressure difference resulting from the pumping action, the water condensing in the pores of the hydrophilic membrane. 1 1

1263DE19922628C1 1 Verfahren zur Steuerung einer Umkehrosmoseanlage SCHAL WILFRIED DR-ING The reverse osmosis apparatus., with a water feed into a buffer vessel (30), has a high pressure pump (20) to take the water from the vessel to a filter module (10) for reverse osmosis. To control the working cycle, a level sensor (40) in the buffer vessel continuously registers the vessel filling level, and is connected to a timer (72). The actual and/or mean values of the inflow and outflow, which change the level in the buffer, are established by an evaluation of the changes in the level by time. The yield, as a relationship between the removal of permeate and the untreated water feed, is determined by the established inflows and outflows. The duration of the concentrate separation phase in the actual cycle is set according to the established data, so that the yield is close to a given threshold value. Within the working cycle, the concentrate separation phase is directly in front of the filling phase where a fresh charge of untreated water is delivere 1

1293DE2920054A1 11 Verfahren zur Vorbehandlung von Rohwasser fuer Reversosmoseanlagen L & C STEINMUELLER GMBH 5270 GUMMERSBACH [From equivalent US4261833] A method of pretreating raw water, for instance sea water, which is intended for supplying reverse osmosis units. An aqueous solution of acid salt and acid with the same anions is mixed with the raw water, whereby the most advantageous pH value is adjusted for the reverse osmosis, and whereby the acid salt is converted into the corresponding hydroxide. After possible addition of flocking or flaking additives, the resulting hydroxide flakes are separated, in a strongly concentrated form, by way of a centrifuge, particularly a plate or disc centrifuge, and together with fresh metal salt, are again brought into solution as a salt by means of the previously mentioned acid and, after mechanical purification in a second centrifuge, likewise particularly a plate or disc centrifuge, are again supplied to the raw water. The pretreated raw water leaves under pressure from the separator through which it flows and, alternatively, a chemical reducing agent may be added to this departing water flow. With a small requirement for metal salts, the recirculation can be eliminated. Also, the addition of the reducing agent to the pretreated raw water can be eliminated. 1

The latter compound must be able to react with the polyfunctional oligomer or polymer and is required only if the said polymer does not already itself contain ionic groups. The novel membranes show good mechanical, temperature and pH-stabilities and are suitable, for example, for separating monovalent ions of low ionic weight from polyvalent ions of low or relatively high ionic weight or from monovalent ions of relatively high ionic weight and for separating ionic compounds from non-ionic compounds or from ionic compounds which have a different molecular weight or opposite charge. They can be used for example for separating salts from organic compounds (dyes) or in waste-water treatment. 1

To maintain the aseptic state, in cases where there is a low consumption or during shutdown or if there is a relatively large requirement for internal water quantities, care must be taken to maintain the aseptic state of the water, for example by providing downstream a reservoir under reduced pressure through which the water continuously flows. Conventional treatment plants which are operated with ion exchangers or reverse osmosis units can be converted for the production of aseptic pure water by the use of a vacuum degasifier. The pure water treated in such a manner satisfies the highest requirements, for example of the pharmaceutical or electronic industr 1

1340DE4117284A1 15 Verfahren zur Herstellung von mikroporoesen Keramikmembranen fuer die Trennung von Gas- und Fluessigkeitsgemischen STUDIENGESELLSCHAFT KOHLE MBH 4330 MUELHEIM DE [From equivalent US5250184] Gas and liquid separation with membranes has either been achieved by organic polymer membranes, which are limited by low temperature stability and a separation mechanism through adsorption or solubility in the membrane matrix, or by inorganic membranes, whose gas and liquid separation efficiency is limited by Knudsen diffusion. The membranes of this invention show a temperature stability up to 500 DEG C and a gas separation with separation factors better than the Knudsen limit. Continuous microporous inorganic membranes of any desirable thickness can be prepared by e-beam evaporation of metal oxides on a support membrane, which has substantially larger pores than the metal oxide membrane. It is advantageous when the support membrane consists of the same material as the microporous membrane. The membranes are of porous structure with a narrow pore size distribution of pores, where the majority of the pores have diameters smaller than 1 nm. The membranes can be used in all areas of gas and liquid separation, where the selective separation of smaller molecules from mixtures is desired (f.e. gas concentration by removal of water from natural gas, hydrogen from synthesis gas). The membranes can also be used for the concentration of aqueous solutions (fruit juices with retention of aroma compounds, vitamines and other compounds important for the flavor and nutritional value of the juice; biological liquids like lymphe, blood, or others with retention of valuable compounds including small peptides, hormones, antibiotics and others) and for the concentration of organic solutions with retention of molecules larger than the solvent including oligomers and polymers.; The membranes can also be used for the concentration of waste water with retention of organic contaminants like phenol resins and coal oil at coking plants. If the membranes have been made catalytically active, the membranes can also be used for the selective and poison resistant conduction of heterogeneously catalyzed three phase reactions by having the reaction gas diffusing through the catalytically active membrane to react at the other side of the membrane with the liquid, consisting of molecules too large to penetrate the pores. 1

1369DE8904566U1 2 Tragbares Filtergeraet SANBORN INC WRENTHAM MASS US (From equivalent US4929351) An inexpensive portable ultra-filtration system for concentrating industrial waste fluids such as cutting coolant. The system is adapted for convenient use with standard storage containers. It is lightweight, portable, and reliable, and processes waste fluids in conformance with most local environmental regulations. Its low cost makes it ideal for small volume applications. The system operates by continuously recycling the waste fluid through a cartridge prefilter and then a carriage ultra-filter. It can process a fifty-five gallon drum of contaminated coolant to yield fifty gallons of clear permeate and only five gallons of concentrated contaminated mixture in about twenty-four hours. The clear permeate can be directly sewered in most locales. An inlet pipe may be used to keep the point of waste fluid intake above most of the heavy contaminants such as sludge, thereby lengthening the operating life of the filters. If necessary, post-process filters for the clear permeate can be conveniently installed in a frame which hangs on the side of a storage container. 1

1533EP56512A1 9 Reverse osmosis membrane and process for making the same BRUNSWICK CORP A desirable reverse osmosis membrane which is particularly useful in water purification includes a thin, active layer (20) of a relatively inert, film forming, polymer which is capable of dissolving a limited amount of water, said active layer being used in association with a porous support (12). This active layer is disposed on a hydrogel layer (16) which serves to facilitate the movement of water away from the active layer generally toward the pores in the support. Preferably the support used is an asymmetric layer or membrane in which the porosity increases with the distance away from the hydrogel layer. The complete membrane can be manufactured through the use of solvent solutions which are successively applied to the support layer or membrane and from which the solvent is removed. 1

1534EP565921A2 4 Rain water treating and conveying installation for use as industrial wateror for treatment for the purpose of infiltration or inflow in receiving water HERRMANN THILO 1. Designation $qInstallation for treating, storing and conveying rainwater for use as utility water or for treatment for percolation or passing into an outfall. $q2. Summary $q2.1 Objective $qThe aim of the invention is low-maintenance and inexpensive treatment, purification and storage of rainwater for use as utility water in homes, industry, commerce and public buildings or for the purpose of percolation or passing into an outfall, taking into account frost-proofing, with low expenditure on maintenance, without parts which wear, with a regenerable filter, with a frost-dependent filling level, with a damming-secured overflow and compact construction. $q2.2 Solution of the technical object $qThe rainwater is purified by rapid sedimentation, filtration through a depth filter and subsequent slow sedimentation. The filter is furnished with a washable, removable filter packing and, by the special construction form, makes possible high filter cross-sectional areas with low structural volume. Variable overdamming makes possible frost-proof laying of the drains in accordance with standards, without loss of filling level in the storage. Devices for forming layers and flow guidance in the storage free the water from suspended matter before withdrawal by slow sedimentation. Variable maximum water level, depending on the external temperature, make the use of an enlarged storage volume possible in frost-free seasons. $q2.3 Area of application $qThe main use of the described installation is the treatment of roof run-off water for utility water purposes. The treatment of surface run-off water from sealed surfaces is equally possible. In addition, the rain run-off from sealed surfaces can be purified by this system prior to percolation or passing into an outfall. 1

An example thereof is one containing both of an antibacterial metal itself and ions thereof. It is generally believed that antibacterial metal ions have a potent antibacterial effect when contained in the sewage at least in a specified concentration but the effect cannot last long because they are rapidly released into the sewage and consumed thereby, while antibacterial metals themselves, though not fast-acting, can exhibit a certain bacteriostatic effect continuously for long. Therefore the antibacterial solid containing both of the metal and ions thereof combines a potent initial antibacterial effect and a persistent bacteriostatic effect.

1585ES2107384AA 2 Development of pressures from tides and waves for desalinating sea water by reverse osmosis UNIVERSITY ALCALA HENARES Drums floating on the sea slide vertically following the variations in sea level on account of waves or tides. Pistons of smaller surface area connected to them thus slide inside fixed cylinders connected to pressure chambers into which the sea water enters via suitable valves, developing high pressures. With suitable surface areas of drums and pistons, the pressures achieved produce desalinated water by reverse osmosis on passing through semipermeable membranes located in the chambers. The yield of desalinated water is proportional to the square of the tidal range or the waves. For 1m2 of drum surface area, it is possible to produce between 10 and 250 litres of water per day with tides and between 1 and 5m3 per day with waves. In general, desalination of sea water using wave and tide energy, through pressure amplification, is patente 1 1

The most economical operation of the membrane separator obtains a maximum amount of a desired liquid with minimum energy, that is, minimizing the amount of energy required per unit of obtained solution. Hitherto, minimum power is obtained at the maximum pressure corresponding to the performance of the semipermeable membrane; consequently, the energy required is not the minimum. According to the invention, there is provided a membrane separator comprising a flow rate controller provided with a control circuit for calculating the minimum necessary power at the flow rate of a dilute or concentrated solution, set according to the pump performance curve, the power-recovering means performance curve and the relationship between the concentration and osmotic pressure of a solute in the solution, wherein the power-recovering means performance curve is also taken into consideration. An embodiment of the invention is provided with a means for detecting the flow rate of a liquid supplied to the membrane separator or of a concentrated or dilute solution therefrom, and a control circuit for adjusting a pressure-regulating valve or a power-recovering means so that the value from the flow rate detecting means is coincident with the theoretical flow rate in the system. Alternately, the flow rate detecting means is provided with, as a pressure detecting means, a control circuit for adjusting the pressure-regulating valve or the power-recovering means so that the value indicated by the pressure detecting means is coincident with the pressure corresponding to the theoretical pressure in the system.

SAFOG SARL [From equivalent FR2665893A1] The objective of the invention is to regulate automatically the effect of a constant field of forces on a moving fluid regardless of the instantaneous flow rate of said fluid. The case of a magnetic water conditioner is examined below. The apparatus is made up of a number of mutually parallel permanent magnets (1) arranged with a position of polarity. A shutter (5) actuated by a spring (6) is placed in the gap (2). In operation, the pressure difference between (3) and (4) pushes back the shutter (5) whose shape, adapted to the shape of the magnets (1), creates 2 lamina flows (8) of variable thickness. Since the distance from the shutter is a function of the flow rate, an automatic regulation of the thickness of the 2 flows (8) is thus obtained. In addition to the treatment of hard water, these regulators can be adopted in applications such as gas distribution, UV radiation, heat exchanges etc.

1631FR2697446B1 4 Procédé de traitement d'un fluide contenant des matières en suspension et en solution, par utilisation de membranes de séparation. AQUASOURCE [From equivalent FR2697446A1] Process for treating a fluid containing suspended and/or dissolved material uses a separating membrane. An adsorption and/or filtration additive (the feed additive) is added to the fluid to be treated and a back-washing additive is added to the back-washing fluid. The back-washing additive is chosen such that it can be neutralised by the feed additive and one allows a sufficient contact time after the ejection of the back-washing fluid for the neutralisation to take place. The resulting product is separated into a concentrated solid residual product and a fluid that can be recycled to the start. Appts. comprises a feed (1,2) for the fluid to be treated; a pipe (2a) with a pump (Po) sending the fluid into a separation module (3); a device for injecting the feed additive into the fluid, with eventual recycling of the untreated fluid through a pipe (6) and pump (P1). The device also comprises a back-washing assembly with a pump (P2) lifting the extracted material into a collection drum (5) and a device for adding the back-washing additive (7,P3) characterised in that the back-washing output is sent to a collection drum (9) from which it is removed by a pump (P4) through a pipe (10) via a separation device (11). From this a concentrated residue of solid material exits through a pipe (13) to a drum (14) and a recycled fluid exits through a pipe (14) to the start (1,2). Alternatively, the back-washing output is sent to a contact/separation device (16) where it stays for long enough to produce a concentrated residue of solid material sent to a drum (14) through a pipe (13) and a recycled fluid sent through a pipe (12) to the start (1,2). USE/ADVANTAGE - Fluid is treated to extract material in suspension or in solution (claimed), for example treating water to make it potable. This system increases the flow through the filter membranes by 30-40%, and the back-washing output is separated and partially recycled, thus reducing the amount of waste to be disposed o 1

Class 46 A portable water filter comprises a flexible liquid container connected by a flexible tube to a filter housing containing filtr a t i o n means. The filtration means may consist of paper comprising between 10 and 40 per cent asbestos fibres which may be impregnated with a bactericide. An adsorptive agent such as an ion-exchange material may be included. Water to be filtered passes outwards from a bag 1a for effecting preliminary filtration into a flexible container 1. Fig. 1. and thence down a flexible tube 2 to a series of small inlet ports 10 in an upper part 3 of a filter housing. The water is distributed laterally in the housing by a mesh screen 8 and then passes through a disc 6 of the paper filter medium clamped between ridges 7 on the upper member 3 and a lower part 4 of the housing screwed thereinto. The filtrate issues from a series of outlet ports 11 in the lower part 4 into the screwed nozzle 5 of a water bottle. The disc 6 preferably is impregnated with a bactericide such as silver chloride; the bag 1a may also be so impregnated. The filter disc may be permeated with an adsorptive agent such as fine granules of activated carbon or with granules of anion- or cationexchange resins, or such agents may be retained in a layer or layers between two or more layers of filtering material. The parts of the filter housing may be made of a transparent plastic material such as polystyrene. In order to ensure that particles of impurities are not forced through the filter by the application of excessive pressure the water in the container 1 should initially be not more than 2 feet above the filter. As the filter disc becomes clogged increased pressure is obtained by raising the container to a higher level at each filling of the container until it is vertically above the filter. In the modification of Fig. 3 the upper part 14 of the filter housing comprises an internally threaded circular recess to receive a disc member 19 having finger holes 20 and a central hole suitably tapered to conform with an externallytapered inlet nozzle 15 for clamping the tube 18. Each of the mesh discs 23 is secured to its respective part of the filter housing by a press-button fastener 24, the neck of which fits loosely in the housing part so that the discs 23 remain stationary with, and thus do not abrade, the filter disc 6 whilst the parts 24, 25 are being screwed together. An internally-screwed bore 27 is provided to receive the nozzle of a water bottle as before; a drip ring 29 prevents water from dripping over the outside of the nozzle. Ridges 30 prevent unfiltered water from coming into contact with the nozzl 1

1781GB9607894A0 4 A portable container for purifying drinking water DALTON KEITH R|DALTON CHARLES S|CHEESEMAN ROGER J [From equivalent GB2312175A] A portable container 2 for purifying drinking water comprises a body portion 6 for containing the drinking water 4, a filter 14 for filtering the water and a air pump for delivering air to an ozone generator 10 in order to produce a mixture of air and ozone. The mixture of air and ozone is delivered via pipe 16 to the drinking water 4 in the body portion 6. This causes the drinking water 4 and the mixture of air and ozone to pass through the filter 14 whereby the filter 14 filters the drinking water. The ozone purifies both the water and the filter 14 i.e. kills the bacteria contained therein. The killing of the bacteria in the filter helps to regenerate the filter thus prolonging its effectiveness. The container may be in the shape of a jug or kettle. There is also shown (FIGS. 2,3) electrical circuits used in generating the ozon 1

Operation process: the filling material of the filter consists of silicon gravel while the filter is vaccinated with indigent water bacterial population. The dimensions of the filter and the height of the filling material are defined by the volumetric supply and the concentration of the water pollutants. Aeration is obtained in a natural manner by the water fall and the temperature difference existing between water being under treatment and ambient air. Oxidation of pollutants is realized either by natural oxidation of mainly by use of adequate micro-organisms able to catalyse distinct reactions. The co-existence of microorganisms demands adequate calculations and operational conditions. Advantage: complete removal of pollutants with no addition of chemicals; very low fixed recurrent cost and nul operational cos 1

The process provides concentrated discharge of waste materials. A process for reducing arsenic, iron, manganese and organic material content of contaminated water, involves pre-treating the contaminated water with chemicals; and applying a two-stage separation to the pre-treated water, where the first stage is a pre-separation in liquid space and the second stage is a membrane separation that provides surface separation. An apparatus for reducing arsenic, iron, manganese and organic material content of contaminated water, comprises a chemical mixing unit; a pre-separating unit; a mud collecting and thickening unit; and a membrane filtering unit for sparing ultra-filtering or micro-filtering. The membrane filtering unit contains a membrane reactor and a submerged membrane unit mounted in the membrane reactor. The submerged membrane unit has an input connected to a first output of the pre-separating unit; and an output connected to an input of the chemical mixing unit through a water flow that needs to be cleaned, or to an input of the mud collecting and thickening unit. The mud collecting and thickening unit has a first output connected to the input of the chemical mixing unit through the water flow to be cleaned. The output from the submerged membrane unit is an output of cleared water of the apparatus. The process provides concentrated discharge of waste materials. In the process, the waste material produced during the pre-separation stage is led from a second output of the pre-separating unit to the mud collecting and thickening unit, while the pre-separated liquid is led from the first output of the pre-separating unit to the membrane reactor of the membrane filtering unit filled with liquid, where a sparing membrane separation is performed in the submerged membrane unit. The thickened product from an output of the membrane reactor, and the water from an output of the mud collecting and thickening unit, are led back to a water flow which is to be cleaned. The concentrated waste product containing arsenic is led away from the output, and the cleared water filtered by the membrane is obtained from the output of the submerged membrane uni 1
