摘要： An electrodialysis desalination device includes a first electrode including a first-stage side; a second electrode including a first-stage side; and a first stage between the first-stage side of the first electrode and the first-stage side of the second electrode. The first stage includes at least one first-stage cell pair positioned between the first-stage side of the first electrode and the first-stage side of the second electrode, and each cell pair includes a pair of first-stage selectively permeable ion-exchange membranes with alternating selectivity that define first-stage channels on opposite sides of each first-stage membrane for respective flows of a first-stage diluate stream and a first-stage concentrate stream. A single pump is configured to pump the diluate streams and the concentrate streams through the first stage.

摘要： Apparatus for purifying a liquid, which comprises a container housing multiple closed cells, each delimited by an anionic membrane and by a cationic membrane, and multiple open cells, susceptible of being traversed by a liquid to be treated and each interposed between two adjacent closed cells. The apparatus also comprises two electrodes which are supplied with supply voltages with reversed polarities in order to push the ionized particles of the liquid into the closed cells during an operating phase, and in order to bring the ionized particles back into the open cells during a regeneration phase. The apparatus also comprises a polymer substance having functional groups with non-zero electric charge, which is contained inside the closed cells in order to create chemical bonds with the ionized particles of the liquid that enter therein.

摘要： An apparatus and method for abating scale formation during the purification and demineralization of water in an electrochemical deionization apparatus. In the apparatus and method, scale forming ions in a raw water feed are precipitated at a controlled location remote from the deionization chambers of the deionization apparatus. Concentrate water produced during the deionization process to produce demineralized product water is acidified and circulated through the deionization apparatus to prevent scale formation and build-up in the deionization apparatus.

摘要： Processes, systems, and techniques for multivalent ion desalination of a feed water use an apparatus that has a cathode, an anode, and an electrodialysis cell located between the cathode and anode. The cell has a product chamber through which the feed water flows, a multivalent cation concentrating chamber on a cathodic side of the product chamber through which the concentrated multivalent cation solution flows, and a multivalent anion concentrating chamber on an anodic side of the product chamber through which the concentrated multivalent anion solution flows. The product chamber and the multivalent cation concentrating chamber are each bounded by and share a cation exchange membrane, and the product chamber and the multivalent anion concentrating chamber are each bounded by and share an anion exchange membrane. A monovalent ion species is added to at least one of the concentrated multivalent cation solution and the concentrated multivalent anion solution.

摘要： A fluid purification system has cells whose purifying capability can be regenerated. Some of the cells are arranged in series to reach a high level of purification. An automatic valve network is controlled to cycle the cells in a way that levels the loads on each, thereby maximizing the service interval for replacing expired cells, enabling all of the cells to be replaced at the same time after having each contributing approximately equally to the purification load, and operated such that at any one time, at least one cell is regenerated so as to enable continuous up-time.

摘要： Electrochemical separation devices are configured for lower energy consumption. Techniques for reducing shadow effect may involve providing distance between a spacer screen and an adjacent ion-selective membrane. A spacer having a screen that is thin relative to a surrounding frame may be used. Mild pressure may also be applied to a compartment to promote distance between a spacer screen and an adjacent ion-selective membrane.
