Abstract: Laundry wash water recycle system comprising a repressurization pump in fluid communication with a storage tank containing previously used wash water for pumping the used wash water sequentially through a lint filter, a cyclone, and a multi-media filter disposed in sequential series wherein the self-cleaning lint filter in sequential series combination with the cyclone removes insoluble solids with the multi-media filter providing a final filtration for obtaining an output of pressurized double filtered cyclonically processed water. An advanced oxidation combination is introduced into pressurized double filtered cyclonically processed water and mixing occurs for producing a double filtered cyclonically processed advanced oxidation treated water that is communicated to a clean water storage tank for providing on demand delivery to at least one washer and continuous delivery of a feedback flow to the inlet storage tank for providing constant recirculation of treated water through the system.

Abstract: A system for and method of sanitizing water and waterway surfaces using ozone gas is disclosed wherein water is circulated from a water reservoir in a water ozonation loop means. Ozone is generated by an ozone generator and dispensed into the circulating water by an ozone feed means. In some embodiments the ozone is generated from gas in the water reservoir and dispensed into the water ozonation loop means at a venturi tube. A controller is provided for activating an ozonation cycle. In some embodiments, the ozonation cycle includes the actuation of a circulating water pump for a cycle interval, and the actuation of an ozone generator during an ozone generation interval, which is less than the cycle interval.

Abstract: Described are water-on-water valves for use in reverse osmosis filtration systems. The water-on-water valves are regulated by the pressure in a product line, which contains fluid from a product line of the filter module and/or the product side of a water-on-water storage tank. Exemplary valves are shuttle valves that are regulated by the pressure downstream of the product side of a reverse osmosis filter module. The valves may comprise a piston within a housing, and an end of the piston may have an enlarged diameter relative to the maximum diameter of the remainder of the piston. The body of the piston may have sections of differing diameters, where the smaller diameter sections form flow channels, or the body may a diameter that is substantially the same along its length in conjunction with gratings and flow channels.

Abstract: An energy-saving water purifying device has a tube, two pistons, a movable component, a pump, and a filter. The two pistons are mounted in the tube. The movable component is moveably mounted between two block portions of the tube. Two magnetic elements are mounted on the movable component and repulse magnetic elements of the two pistons. The movable component selectively blocks one of two wastewater entrances of the tube. An outlet of the pump is connected to two check valves of the two inlets in parallel. An inlet of the filter is connected to two check valves of the two outlets in parallel. A wastewater exit of the filter is connected to the two wastewater entrances of the tube in parallel. The water purifying device is switched by magnetic force so that the structure is simplified, energy is saved, and cost and fault rate are decreased.
