The invention relates to a system for the ionisation of water by electrolysis, for swimming pools, operating by means of mechanical kinetic energy of the water driven from the filtration system of a swimming pool. The invention relates to a system for the ionisation of water of swimming pools or tanks by electrolysis. Said pools or tanks must be provided with a water circulation system. The system can be easily installed in all types of swimming pool without affecting the original character thereof, and uses an autonomous and safe source of energy, the electric power being generated by the kinetic energy accumulated in the water, produced by the driving system for the filtration of the swimming pool water. This energy is used both for the generation of electricity used in the production of ions by electrolysis, and as a source for indicating operation. Kinetic energy is also used as a source of energy for the element for actuating the electrode cleaner.

Described herein are methods and apparatus for solid-liquid separation with high efficiency, especially in treating spent filter backwash and sedimentation tank sludge produced in the water treatment process. It combines and applies gravity, electromagnetic force, dynamic filtration, and gravity condensation, magnetic and gravitational compression in one integrated device that produces high quality effluent water (less than 10 ppm suspended solid) and highly condensed sludge (less than 94-96% water content).

An automatic water faucet device 1 includes: an electrolysis tank 37 that electrolyzes water to generate electrolyzed water; a second water discharge part 13 for discharging the electrolyzed water, a second flow path 18 that extends from the electrolysis tank 37 to the second water discharge part 13; a second solenoid valve 28 that switches between supply and blocking of normal water with respect to the electrolysis tank 37, and a controller 40 that controls the electrolysis tank 37 and the second solenoid valve 28. The controller 40 energizes the electrolysis tank 37 to discharge the electrolyzed water and thereafter stops the energization of the electrolysis tank 37 and maintains an open state of the second solenoid valve 28, to stop the supply of the electrolyzed water to the second flow path 18 and to supply normal water to the second flow path 18.

A fluid circuit includes a plurality of tubing segments and a plurality of operative components. Each tubing segment includes i) a non-conductive polymer portion defining a fluid passageway and ii) one or more interior conductive fluoropolymer stripes extending axially to the ends of each of the respective tubing segments. Each operative component includes a conductive fluoropolymer that extends between a plurality of tubing connector fittings forming a part of the fluid circuit, wherein each of the tubing connector fittings conductively connect the respective conductor of the operative component to the interior conductive fluoropolymer stripes of the tubing segment to provide a path to ground that extends through each operative component and each tubing segment.

A system for reducing evaporative cooling water losses using an electric and magnetic field inducing device is disclosed. The device influences a liquid's properties including evaporation rate, diffusion, vapor, heat transfer rate, and/or fluid properties. The device comprises a malleable core with notches and electrically conductive windings wrapped around the flexible core around the notches. An insulative coating isolates the windings from the core. The device is pliable and is wrapped and/or attached around a conduit (e.g., a makeup line or pipe or a recirculating line or pipe of an evaporative cooling tower) with flowing fluid and current is passed through the windings to treat the fluid.

An efficient, cost-effective, and efficacious technique for removing coal ash and other pollutants from waterways, ponds, marshes, holding tanks and other water sources and supplies. An apparatus comprising an open cage including electromagnets and/or permanent magnets and/or electrodes is supplied with electrical power to extract materials such as rare earth elements and/or heavy metals. The materials levitate to the surface, forming a shiny while leaving water substantially free of such materials.

Wastewater containing scale components, organic substances, inorganic ions, and the like, such as human effluent, generated in a closed system space, such as a nuclear shelter, a hazardous shelter, a space station or a moon-Mars mission manned spacecraft, or a lunar base is efficiently treated by a simple structural apparatus, so that water is recovered. After a hardness component is removed from water to be treated, such as human effluent, by a softening device, and heat exchange is performed between softening treated water and electrolysis treated water by a heat exchanger, by a high-temperature and high-pressure electrolysis device, organic substances, urea, ammonia, and the like are removed by electrolysis performed under high-temperature and high-pressure conditions. After the electrolysis treated water is processed by a deaeration treatment using a deaeration membrane device, a desalting treatment is performed by acid/alkali manufacturing electrodialysis devices and provided in series at two stages.

The present invention relates to an elongate microreactor (1) for desalinating a saline fluid (2), comprising at least one compartment (C1) for migrating ions, at least one compartment (C2) for separating ions and at least one compartment (C3) for collecting fluid, characterised in that first and second cathode electrodes (11A, 11B) and first and second anode electrodes (12A, 12B) each have a first surface (11F, 11G, 12F, 12G) that is in contact with the air and a second surface (11E, 11H, 12E, 12H) opposite said first surface, respectively, said second surface being in direct contact with a plastic wall (13B, 13C, 13A, 13D) that is in direct contact with the saline fluid.

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.
