Abstract: 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.

Abstract: Processes, systems, and techniques for treating produced water drawn from a subterranean formation. The produced water is provided and contains dissolved solids and magnesium, calcium, and sodium ions. The produced water is desalinated using an electrically-driven membrane separation apparatus that includes alternating anion exchange membranes and cation exchange membranes defining opposing sides of alternating product and concentrate chambers. The desalinating involves flowing the produced water through the product chamber, flowing a second water through the concentrate chamber, and applying an electric potential across the cation and anion exchange membranes as the produced and second waters flow through the product and concentrate chambers, respectively. The product water is consequently produced and has a total dissolved solids content of between 300 mg/L and 8,000 mg/L, a total concentration of calcium ions and magnesium ions less than 100 mg/L, and a sodium adsorption ratio of 20 to 90.

Abstract: The present disclosure is directed at an apparatus, method and plant for desalinating saltwater and contaminated saltwater. The apparatus includes a stack and a manifolding assembly. The stack includes a product chamber, a first and second concentrate chamber, an anion exchange membrane forming a boundary between the first concentrate chamber and the product chamber and a cation exchange membrane forming a boundary between the second concentrate chamber and the product chamber. The manifolding assembly includes product and concentrate manifolding fluidly coupled to the product and concentrate chambers respectively, to convey a saltwater being desalinated to and away from the product chamber, and a concentrate to and away from the concentrate chambers. The stack may include a diluent chamber and adjacent anion or cation exchange membranes between the product chamber, diluent chamber and concentrate chamber to respectively convey anions or cations across multiple chambers.
