Abstract: Cations that can precipitate from an aqueous composition to produce scaling are sequestered by adding a multi-dentate ligand to the aqueous composition. The multi-dentate ligand bonds with the cation to form a non-scaling ionic complex; and the aqueous solution with the ionic complex is used in a process that produces substantially pure water from the aqueous composition, where the cation, absent formation of the ionic complex, is subject to scaling. The pH of the aqueous composition (or a brine including components of the aqueous composition) is then reduced to release the cation from the multi-dentate ligand; and the multi-dentate ligand, after the cation is released, is then reused in a predominantly closed loop.

In the electrodeionization apparatus for producing deionized water, at least one deionization treatment unit including the deionization chamber and a pair of concentration chambers adjacent to both sides of the deionization chamber is disposed between a cathode and an anode. In the deionization chamber, anion exchanger layers and cation exchanger layers are stacked in an order in which a last ion exchanger layer through which water to be treated passes is an anion exchanger layer. A bipolar membrane is formed on the cathode side of the anion exchanger layer in the deionization chamber. The anion exchange membrane of the bipolar membrane is in contact with the anion exchanger layer.

Abstract: An energy exchange chamber is used for exchanging pressure energy between concentrated seawater discharged from a reverse-osmosis membrane-separation apparatus and a part of seawater to be treated by the reverse-osmosis membrane separation apparatus in a seawater desalination system. The energy exchange chamber includes a concentrated seawater distributor communicating with a concentrated seawater port and configured to distribute a flow of the concentrated seawater flowing therein all over a horizontal plane of an interior of a chamber, and a seawater distributor communicating with a seawater port and configured to distribute a flow of the seawater flowing therein all over a horizontal plane of the interior of the chamber. The concentrated seawater and the seawater introduced into the chamber are brought into direct contact with each other over the horizontal plane of the interior of the chamber to exchange pressure energy between the concentrated seawater and the seawater.

Abstract: Disclosed is an improved method for the remineralization of process water in a desalination system. The method sequesters carbon dioxide gas (CO2) from seawater or concentrate (brine) of desalination process via a gas transfer membrane. The sequestered carbon dioxide gas (CO2) is thereafter used in the production of soluble calcium bicarbonate (Ca(HCO3)2). The calcium bicarbonate (Ca(HCO3)2) adds hardness and alkalinity to the resulting process water.
