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: 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: Methods, systems, and techniques for removing ammonium from ammonia-containing water involve using a stack that has alternating product chambers and concentrate chambers for receiving ammonia-containing water and an acidic solution, respectively, with the chambers being bounded by alternating cation exchange membranes and proton permselective cation exchange membranes. Ammonium moves from the product chambers to the concentrate chambers across the CEMs and protons move from the concentrate chambers to the product chambers across the pCEMs when the stack is in use. An electrolyzer may also be used to convert the ammonium in the concentrate chambers into nitrogen.
