摘要： 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 membrane.

摘要： A non-membrane type electrolytic cell (10) comprised an anode plate (16, 20) and a cathode plate (18) which are arranged opposite to each other with an electrically insulating spacer (22) sandwiched therebetween. The spacer (22) is formed of plastics having a water absorption of not more than 0.3%, preferably not more than 0.2%, more preferably not more than 0.01%. Deposition of scale, such as calcium carbonate, on the spacer (22) is prevented.

摘要： An electrolytic cell (10) for generating a mixed oxidant that is rich in ozone is disclosed. The cell disassociates a brine solution to generate ozone and chlorine based oxidants. The improved cell design allows the ratio of ozone to the other oxidants to be optimized, thereby providing a more efficient sterilization solution. The ozone production is adjusted by adjusting the residence time of the brine solution in the cell and the orientation of the cell.

摘要： A hydraulic control and/or safety device, particularly for utility apparatuses or systems or appliances, which is preferably able to carry out a flow shut-off and/or limitation, particularly in the event of fault of the utility apparatus or system or appliance, and/or one or more features that improve the device and/or the apparatus performance. In particular, the device can carry out the function of the fluid treatment, so as to be particularly reliable, as it prevents at least the formation of deposits on its mechanical components designed to limit the water flow.

摘要： Plant for desalinating water of a water supply system, which comprises one or more tanks for accumulating water (2) in an immiscible manner, in order to store a softened supply thereof, provided with a first inlet connection (3) and with a first outlet connection (4) respectively connected to a feeding pipe (5) connected to the water supply system (50) and to an extraction pipe (6) for supplying users. The plant (1) also comprises a filtering unit (10) for water softening, for example obtained with a flow-through condenser (10″) or with a reverse osmosis membrane filter (10′), connected in parallel to the tank (2) with second inlet connection (11) and second outlet connection (12) respectively hydraulically connected to the first inlet connection (3) and to the first outlet connection (4) of the tank (2). Circulating means (13) are provided which can be activated to force at least one water flow to be treated to pass through the filtering unit (10), producing a filtered water flow, which is progressively stored in the tank (2) according to a filling direction (VI) thereof. Operatively, the feeding pipe (5) of the water supply system (50) forces, when the user requests water, a water flow intended for use to flow through the tank (2), causing the at least partial evacuation of the filtered water volume that was stored therein in an immiscible manner, in an evacuation direction (V2) opposite the filling direction (VI) with which the filtered water flow had been previously stored in the tank 2.

摘要： An apparatus for treating water in a reservoir includes a funnel. A support assembly supports the funnel in a lengthwise upright orientation when the funnel is submerged. A water moving arrangement is arranged to move water through the funnel in a direction from an inlet at an upper end of the funnel towards an outlet at lower end of the funnel.
