Publication number: 20120312756Abstract: A water treatment system is provided including a tank having a top, a control valve, and an air inlet. The control valve is positioned on the top of the tank and in fluid communication with the tank. The control valve includes a plurality of orifices in fluid communication with a source of untreated water, a treated water outlet, a drain, and a source of sterilizing fluid. The air inlet is in fluid communication with the tank and with a first venturi. The control valve is operative to control the flow of untreated water through the first venturi to draw air through the air inlet and into the tank. The control valve includes a sterilizer valve that is operative to open and close at least one passage in fluid communication between the control valve and the source of sterilizing fluid.Type: ApplicationFiled: June 8, 2012Publication date: December 13, 2012Applicant: CHANDLER SYSTEMS, INC.Inventor: William D. Chandler, JR.

Patent number: 8318020Abstract: When a separation membrane (3) is washed with a chemical solution that is a sodium hypochlorite solution, which has a high concentration, diluted with membrane treated water stored in a chemical solution tank (6), an ammonic nitrogen concentration in membrane-treated water is monitored with a monitoring device (9), and a control device (8) controls a chemical solution dosing pump (7) using the concentration measured by the device (9) to adjust a dilution rate. Thereby, even when water quality of membrane-treated water varies, a sodium hypochlorite concentration in backwashing water can be retained constant, and fluctuation in the chemical washing effect can be prevented.Type: GrantFiled: March 2, 2007Date of Patent: November 27, 2012Assignee: Metawater Co., Ltd.Inventors: Koichiro Kando, Motoharu Noguchi

Patent number: 8313716Abstract: A spinning fluids reactor, includes a reactor body (24) having a circular cross-section and a fluid contactor screen (26) within the reactor body (24). The fluid contactor screen (26) having a plurality of apertures and a circular cross-section concentric with the reactor body (24) for a length thus forming an inner volume (28) bound by the fluid contactor screen (26) and an outer volume (30) bound by the reactor body (24) and the fluid contactor screen (26). A primary inlet (20) can be operatively connected to the reactor body (24) and can be configured to produce flow-through first spinning flow of a first fluid within the inner volume (28). A secondary inlet (22) can similarly be operatively connected to the reactor body (24) and can be configured to produce a second flow of a second fluid within the outer volume (30) which is optionally spinning.Type: GrantFiled: July 31, 2009Date of Patent: November 20, 2012Assignee: University Of Utah Research FoundationInventors: Jan D. Miller, Jan Hupka, Robert Aranowski

Patent number: 8303823Abstract: Nanoscale additives and methodology for their use during polymer-aided sludge dewatering to increase the dewatering efficiency compared to traditionally used polymer-only dewatering processes. The nanoscale additive increases the percent solids in the dewatered cake compared to polymer-only treatment. When the nanoscale additives are added, the centrifugal force (shear) required to obtain high percent solids can be significantly reduced and the optimum polymer dose required for effective dewatering is also significantly reduced.Type: GrantFiled: February 9, 2010Date of Patent: November 6, 2012Assignees: NEI, Corp and Kennedy, Jenks Consultants Inc.Inventors: Ganesh Skandan, Runqing Ou, Rajagopalan Ganesh
