  • Patent number: 12180103
    Abstract: A water treatment system for producing potable water and water for irrigation from saline water, the system includes an electrodialysis apparatus including one or more monovalent selective membranes and having an inlet fluidly connectable to a source of water to be treated, a diluate outlet, and a concentrate outlet, a nanofiltration apparatus positioned downstream of the electrodialysis apparatus and having an inlet fluidly connectable to the diluate outlet of the electrodialysis apparatus, a permeate outlet, and a retentate outlet, and an electrolyzer in fluid communication with one of the concentrate outlet and the retentate outlet, and configured to generate a product stream including one or more of chlorine gas, hypochlorite ion, sodium hydroxide, sulfuric acid, hydrochloric acid, or sodium hypochlorite.
    Type: Grant

  • Patent number: 11814305
    Abstract: An electrochlorination system comprises a source of feed fluid, a product fluid outlet, and a plurality of electrochemical cells connected fluidically between the source of feed fluid and the product fluid outlet. The system is configured to operate at least one of the plurality of electrochemical cells at one of a first current density or a first flow rate, and to operate another of the plurality of electrochemical cells at a second current density or second flow rate different from the respective first current density or first flow rate.

  • Patent number: 11208338
    Abstract: A system containing a reactor vessel including zero valent iron media, a source of a conditioning additive, a source of a reaction additive, and a process control subsystem is disclosed. A method for reducing a concentration of one or more contaminants in contaminated water including contacting zero valent iron media with a conditioning additive, contacting contaminated water with conditioned zero valent iron media, and introducing a reaction additive is also disclosed. The conditioning additive and reaction additive may each contain an aluminum salt.
