Patent number: 8894834Abstract: 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 such as an electrodeionization device. The water treatment system has a sensor or a set of sensors for measuring at least one property of the water or an operating condition of the treatment system.Type: GrantFiled: December 19, 2005Date of Patent: November 25, 2014Assignee: Evoqua Water Technologies LLCInventors: Evgeniya Freydina, Anil D.

Patent number: 8864971Abstract: A treatment system provides treated or softened water to a point of use by removing at least a portion of any undesirable species contained in water from a water source. The treatment system can be operated to reduce the likelihood of formation of any scale that can be generated during normal operation of an electrochemical device. The formation of scale in the treatment system, including its wetted components, may be inhibited by reversing or substituting the flowing liquid having hardness-causing species with another liquid having a low tendency to produce scale, such as a low LSI water. Various arrangements of components in the treatment system can be flushed by directing the valves and the pumps of the system to displace liquid having hardness-causing species with a liquid that has little or no tendency to form scale.Type: GrantFiled: February 15, 2013Date of Patent: October 21, 2014Assignee: Evoqua Water Technologies LLCInventors: Anil D. Jha, Frederick C. Wilkins, Evgeniya Freydina, Aytac Sezgi, Reshma Madhusudan

Patent number: 8658043Abstract: A water treatment system provides treated water to a point of use by removing at least a portion of any hardness-causing species contained in water from a water source, such as municipal water, well water, brackish water and water containing foulants. The water treatment system typically receives water from the water source or a point of entry and purifies the water containing at least some undesirable species before delivering the treated water to a point of use. The water treatment system has a pressurized reservoir system in line with an electrochemical device such as an electrodeionization device. The water treatment system can have a controller for adjusting or regulating at least one operating parameter of the treatment system or a component of the water treatment system. The electrochemical device can be operated at a low current and low flow rate to minimize water splitting or polarization, which minimizes scale formation.Type: GrantFiled: December 7, 2010Date of Patent: February 25, 2014Assignee: Siemens Water Technologies LLCInventors: Frederick Wilkins, Evgeniya Freydina, Aytac Sezgi, Reshma Madhusudan, Anil D.

Patent number: 8114260Abstract: 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 controller for adjusting or regulating at least one operating parameter of the treatment system or a component of the water treatment system to optimize the operation and performance of the system or components of the system. A flow regulator regulates a waste stream flow to drain and can be operated to recirculate fluid through electrode or concentrating compartments of an electrochemical device and can opened and closed intermittently according to a predetermined schedule or based on an operating parameter of the water treatment system.Type: GrantFiled: June 2, 2009Date of Patent: February 14, 2012Assignee: Siemens Industry, Inc.Inventors: Frederick C.
