    Abstract: Zero liquid discharge systems, processes, and techniques for treating a saltwater without evaporative crystallization. The saltwater is treated by a fluidic circuit comprising a high-pressure reverse osmosis ("HPRO") unit configured to operate at a hydraulic pressure of at least 1,500 psi, a cooling crystallizer, and a solids-liquid separator. The saltwater is first concentrated by the HPRO unit to produce an HPRO brine, which is subsequently cooled to a designated crystallization temperature by the cooling crystallizer. The cooling crystallizer crystallizes salt crystals from the cooled HPRO brine and produces a salt-diminished brine. The solids-liquid separator separates the salt-diminished brine from the salt crystals. The salt-diminished brine from the solids-liquid separator is returned to the HPRO unit for further treatment, which allows additional salts to be crystallized from the returned salt-diminished brine.

    Abstract: A process for producing a resilient ion exchange membrane. The process comprises the steps of (1) selecting a porous matrix, (2) saturating the porous matrix with a homogenous solution comprising a mixture of: (i) a hydrophilic ionic monomer, (ii) a hydrophobic cross-linking oligomer and/or a comonomer, (iii) a free radical initiator, and (iii) a solvent for solubilizing the hydrophilic ionic monomer, the hydrophobic cross-linking oligomer and/or comonomer, and the free radical initiator into a homogenous mixture. (3) removing excess homogenous solution from the saturated porous matrix, (4) stimulating release of free radicals from the free radical initiator thereby initiating a polymerization reaction to form a cross-linked ion-transferring polymer substantially filling the pores and covering the surfaces of the porous matrix thereby forming a membrane, (5) washing the membrane to remove excess solvent, and (6) optionally bathing the washed membrane in a sodium chloride solution to selectively cross-link sodium or chloride ions to and within the ion-transferring polymer.

    Abstract: A hybrid electrochemical water softening desalination system softens water by both electrodialytical and non-electrodialytical means before desalinating the softened water in a primary desalination subsystem. The concentrate produced as byproduct from the desalination is provided to a concentrate channel of the electrodialysis device employed, and the electrodialysis device extracts multivalent ions from the water to the concentrate channel. In some embodiments the electrodialysis device provides softened water directly to the primary desalination subsystem. In other embodiments the electrodialysis device provides electrodialytically softened water to a non-electrodialytical softening subsystem for further softening, before the softened water is supplied to the primary desalination subsystem. The arrangement integrates the concentrate disposal line of the primary desalination subsystem with the functioning of the electrodialysis device.
