Inorganic salts are removed from an unpotable water stream, which contains suspended living microorganisms and their debris products, particularly seawater or agricultural field drainage water. Chemicals such as caustic soda and/or chlorine, and derivatives therefrom, sterilize the water and remove from it certain dissolved and suspended constituents. From the sterilized water is separated a more concentrated stream of waste brine containing debris and other suspended materials, and most of the dissolved sodium chloride. From the remaining portion of the water is separated a more concentrated stream of sodium chloride, which is electrolized to provide a source of caustic soda, chlorine, and derivatives therefrom; the less concentrated portion is recovered as a source of potable water.
