| 20110120953 | WATER TREATMENT SYSTEM AND METHOD - A method and apparatus for producing purified water. Treated water may be provided for domestic use wherein the water may be treated by removing selected dissolved species while retaining properties that may improve the properties or aesthetics of the water. | 05-26-2011 |
| 20110120886 | WATER TREATMENT SYSTEM AND METHOD - 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. | 05-26-2011 |
| 20090236235 | WATER TREATMENT SYSTEM AND METHOD - 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. The flow regulator can also be charged so that ionic species can be generated in the surrounding fluid, which, in turn, can lower the pH of the surrounding fluid. | 09-24-2009 |
| 20090095685 | VIBRATORY MIXER - A treatment system including a vibratory mixer is disclosed. The vibratory mixer comprises a vibrating element to facilitate the dissolution of a treating agent that facilitates separation of solids from liquids in water and wastewater streams. Vibratory mixing energy that effects mixing is generated by utilizing magnetostrictive or piezoelectric materials. | 04-16-2009 |
