Patent number: 8318011Abstract: A portable water disinfecting and purification apparatus comprising a first chamber into which water to be purified may be drawn by suction or negative pressure, a second chamber into which the water from the first chamber can be forced by a pumping action or positive pressure, whereby the water is initially passed across a pre-filter secured over the inlet to the first chamber and having a very small pore size and an inner cavity in which a disinfecting agent is place to filters most contaminants before the water is drawn into said filtering device, and once in the first holding chamber the water is isolated and may be further treated with a disinfectant agent, and then is passed though at least additional filtering substance including an activated carbon or nano-filter.Type: GrantFiled: October 15, 2009Date of Patent: November 27, 2012Assignee: Miracle Straw Corporation, Inc.Inventors: Paul W. O'Brien, Mogens Engel

Patent number: 8308937Abstract: A grey water diversion system is provided. An interceptor includes an inlet, a filter, an outlet, and an orifice. The filter is located along a bottom of a water flow path from the inlet to the outlet and delivers water to the orifice as filtered water. A gas pump, connected to a filter stem, delivers gas to the filter via the stem when the system detects the presence of the water. The gas rises through the filter to raise debris from the filter to the water flow path. A water overflow delivers the debris to the outlet. A suction manifold, including a sensor, receives the filtered water from the orifice. The sensor detects the presence of the filtered water. A water pump receives the filtered water from the manifold, activates when the sensor detects the presence of the filtered water, and delivers the filtered water into a water usage system.Type: GrantFiled: August 3, 2009Date of Patent: November 13, 2012Assignee: Advanced Waste Water SystemsInventor: Samandar Milani

Patent number: 8303806Abstract: Fluid processing apparatuses and systems are disclosed. In some embodiments the fluid processing apparatuses include a movable enclosure, a plurality of filter housings disposed substantially within the movable enclosure, and a stand disposed within the enclosure. The filter housings are in fluid communication with one another. Each filter housing defines an elongate path and is configured to support a respective filter along the elongate flow path to filter a substantially continuous flow of fluid. The stand supports each filter housing such that the elongate flow path of each filter housing is substantially parallel to a vertical axis, wherein each filter housing is independently rotatable, relative to the stand.Type: GrantFiled: February 9, 2010Date of Patent: November 6, 2012Assignee: Planar Solutions, LLCInventors: Saeed H. Mohseni, Deepak Mahulikar
