Patent number: 8083936Abstract: The production of purified water from a residential reverse osmosis drinking water system is limited by the pressure build up in the holding tank or reservoir. While the pressure in the tank increases the brine or waste water continues to flow at a constant rate. This condition makes an undesirable out of proportion relationship between the purified water and the waste water. The production of product water is controlled by the differential pressure across the purification membrane, as the tank pressure increases the differential pressure decreases and reduced production of product water results. The purpose of the device is to utilize the increasing tank pressure as a force to actuate the valve that proportions the waste water in a direct relationship with the product water. The ratio between the product water and the waste water remains constant during the period that purified water is being delivered to the holding tank.Type: GrantFiled: March 3, 2009Date of Patent: December 27, 2011Inventor: Robert Walker

Publication number: 20100307963Abstract: A water filtration system utilizing line pressure is disclosed. The water filtration system comprises an optional carbon or KDF filter unit or a series of membranes, line pressure filter system, water tank and water pump. Water from a pressurized water source (e.g., municipality water or well) is passed through the carbon or KDF filter and line pressure filter system prior to being deposited into the water tank. A pressure-regulated pump draws water from the water tank upon demand. An automatic pressure regulator on the pump ensures that the water pressure at water-dependent devices (e.g., showers) remains at a desired level regardless of demand. An optional ozone generator may also be incorporated into the system such that water in water tank is provided with O3. A second water tank may be dedicated to holding and supplying non-purified water thereby eliminating any waste water.Type: ApplicationFiled: July 29, 2010Publication date: December 9, 2010Applicant: THE GOOD WATER COMPANY, INC.Inventor: Michael E.

Patent number: 7846340Abstract: A water treatment system provides treated or softened water to a point of use by removing a portion of any hardness-causing species contained in water from a point of entry coming from a water source, such as municipal water, well water, brackish water and water containing foulants. The water treatment system typically treats the water containing at least some undesirable species before delivering the treated water to a point of use. The water treatment system has a reservoir system in line with an electrochemical device. The electrochemical device of the water treatment system is operated at a low current and low flow rate to minimize water splitting or polarization, which minimizes scale formation.Type: GrantFiled: November 13, 2003Date of Patent: December 7, 2010Assignee: Siemens Water Technologies Corp.Inventors: Evgeniya Freydina, Anil D.

Patent number: 7833410Abstract: In systems for treating wastewater liquid by utilizing aerobic biological species, the contaminated wastewater stream is pretreated in a dissolved air flotation system to remove suspended solid waste, including large particles such as fats, grease, and physically emulsified oils. The purified wastewater containing dissolved waste is thereafter gasified and further decontaminated in a bioreactor tank. Biological species in the bioreactor tank consume gas and perform bodily functions that converts dissolved waste into easily removable carbon dioxide and suspend solids. Gas consumed by the biological species is replenished by pumping the wastewater though a liquid-gas mixer. A controller regulates the speed of the pump based on real-time gas concentration measurements provided by a corresponding gas probe disposed within the wastewater in the bioreactor tank.Type: GrantFiled: November 11, 2009Date of Patent: November 16, 2010Inventor: Dwain E.
