Abstract: 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. The electrochemical device of the water treatment system is operated at a low current and low flow rate to minimize water splitting or polarization, which minimizes scale formation.

Abstract: The present invention generally relates to devices able to purify fluids electrically that are contained within pressure vessels, as well as to methods of manufacture and use thereof. Liquids or other fluids to be purified enter the purification device and, under the influence of an electric field, are treated to produce an ion-depleted liquid. Species from the entering liquids are collected to produce an ion-concentrated liquid. Increasing the exterior pressure on the device may reduce the pressure difference between the interior of the device and the exterior, which may reduce manufacturing costs or simplify construction.

Abstract: An electric deionized water production apparatus in which a direct current field is applied to a deionizing chamber packed with an ion-exchange material such that ions to be discharged are allowed to migrate in the direction identical or opposite to the direction of the water flow in the ion-exchange material, whereby ionic impurities adsorbed in the ion-exchange material are discharged from the system, the ion-exchange material being a mixture of a monolith-shaped organic porous ion-exchange material and ion-exchange resin particles. The electric deionized water production apparatus has a simple structure that can reduce material cost, process cost, and assembly cost, capable of accelerating migration of the adsorbed ionic impurities to facilitate discharge of the adsorbed ions and free from a deflected flow due to swelling or shrinkage accompanying an ion-exchanging reaction, and from poor contact with an ion-exchange membrane.
