    摘要： An improved electrodeionization apparatus and method are provided. The electrodeionization apparatus includes electrolyte compartments, ion-concentrating, and ion-depleting compartments, having electroactive media therein. The electroactive media can be induced to have a reversible change in its chemical or electrical properties upon imposition of an external electrical field or the presence of an electrically charged substance. The change in chemical or electrical properties of the media results in a desired change in the transport or chemical properties of the media. The incorporation of the improved electroactive media also provides for an improved, and more reliable electrodeionization process in applications requiring chemical and temperature resistance media, where localized pH shifts would be harmful to the product being deionized, under temperature and chemical conditions of the liquid to be processed, or under circumstances where traditional media would tend to foul.

    摘要： A water treatment system (10) 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 (14) coming from a water source, such as municipal water, well water, brackish water and water containing foulants. The water treatment system (10) typically treats the water containing at least some undesirable species before delivering the treated water to a point of use. The water treatment system (10) 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 (32c-32g) regulates a waste stream flow to drain (26) and can be operated to recirculate fluid through electrode or concentrating compartments of an electrochemical device (16) and can opened and closed intermittently according to a predetermined schedule or based on an operating parameter of the water treatment system (10). The flow regulator (32c-32g) 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.

    摘要： The present invention is directed to a water treatment or purification system and method for providing treated water in industrial, commercial and residential applications. The treatment system provides treated or softened 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 includes an electrochemical device, such as an electrodeionization device, that can have at least one compartment that generates and traps hydrogen ions which can be used in another compartment of the electrochemical device such as, an electrode compartment, to reduce or at least dissolve any scale. Other applications of the system would be in the treatment and processing of foods and beverages, sugars, various industries such as the chemical, pharmaceutical, waste water treatment and power generating industries.
