  • CATION-EXCHANGE MEMBRANE WITH IMPROVED MONOVALENT SELECTIVITY, MANUFACTURING AND USES THEREOF IN ELECTRODIALYSIS
    Publication number: 20230018035
    Abstract: Disclosed herein a monovalent-ion-selective composite membrane comprising a polymeric cation exchange membrane and a metal-oxide-based layer, wherein said metal-oxide-based layer comprises a metal oxide or an organic-inorganic hybrid polymer, of e.g. Zn, Al, Mg, Si, Cu, W, Ni, or Ti. Also disclosed are the methods for the preparation of the membrane, and also electrodialysis assemblies comprising the membranes.

  • Method for separation of magnesium and calcium ions from saline water, for improving the quality of soft and desalinated waters
    Patent number: 11279643
    Abstract: Provided is a novel Nanofiltration-DiaNanofiltration (NF-DiaNF) system and method for extracting divalent ions from saline water (e.g., seawater) to produce solutions rich in divalent ions (in particular Mg2+, Ca2+ and SO42?), while minimizing the concentrations of undesirable species (e.g., Cl?, Br?, B and Na+). The solutions may be added to water (e.g., desalinated, soft, drinking or irrigation water) to enrich the water with divalent ions, thereby improving its quality.

  • Removal of nitrates from ground water
    Patent number: 10766800
    Abstract: The present invention relates to a process for the selective removal of nitrates from ground water using a hybrid nanofiltration (NF)—reverse osmosis (RO) filtration system. The process generates product water that is low in nitrate and can be used for drinking, irrigation and other purposes, as well as waste water that is relatively low in salinity and can be safely discarded to sewage systems and recycled, e.g., for irrigation purposes.
