Electrocoagulation Units for Distillation/Desalination - Water and Wastewater - Water Filtration and Separation
Ultra pure potable water can be produced from salt water without reverse osmosis brine water pollution, using vapor recompression distillation. Vapor recompression distillation allows you to produce ultra pure water and marketable salt, without producing any harmful by products for the environment. Ultra pure potable water can be produced from salt water without reverse osmosis brine water pollution, using vapor recompression distillation for 0.15 KW per gallon of water produced. The sodium chloride is concentrated to a marketable concentration between 20 and 50% solids. This eliminates the reject stream of concentrated brine from reveres osmosis units that kill the wild life, plants, and fish in the discharge bays.
Traditional reverse osmosis desalination technology rejects up to 70% of the incoming saltwater stream. The salt concentrated rejected water is usually placed back into the bay or incoming water source, killing the plant and animal life with excess salt concentration. With vapor recompression distillation the salt is removed in a solid form between 20 and 50%. The salt can be packaged and sold for animal feed, water softeners, road de icing, etc or the concentrated salt can easily be shipped out to sea where the concentrated salt will not harm the coastal wildlife.
Because vapor recompression distillation reused much of the input energy, the process produces a gallon of ultra pure distilled water for 0.15 KW of electricity per gallon or one cent per gallon with electricity costs at $0.07 per KWH.
