摘要： A high salinity water purification system and process, including a forward osmosis system and a reverse osmosis or nanofiltration system. A concentrated brine of a zinc or iron complex combined with a salt or acid draws pure water across the FO membrane from the influent water. The diluted brine is pumped through a vessel holding an anionic adsorption media to remove the zinc or iron complex and the resultant brine is passed through the RO or nanofiltration system to obtain purified water and a concentrated brine stream. The adsorption media is regenerated by a rinse cycle using fresh water or water from the RO system, removing the zinc or iron complex adhered to the media. The resultant brine is stored and mixed with the output of the RO system. Charged membrane can be used as a standalone membrane in FO process or in combination with resin or resin embedded membrane.

摘要： A high salinity water purification system and process, including a forward osmosis system and a reverse osmosis or nanofiltration system. A solids membrane separation system removes solids from the influent water being processed. A pervaporation (PV) system eliminates liquid impurities from the influent water being processed.

摘要： Disclosed is a combined generator technology for two purposes: 1) electrodialysis “salt splitting” (ESS) to convert sodium chloride salt into an acid (hydrochloric or sulfuric) and a caustic (sodium hydroxide) to be generated for use as regeneration solutions for weak acid cation, weak base anion, and strong base anion resin systems and 2) electro-generation for converting sodium chloride salt into an aqueous solution of sodium hypochlorite both with the intention of treating make up water and/or recirculating in a cooling tower, fluid cooler, or any evaporative cooling device; other salts will apply to the process in addition to sodium chloride (example sodium sulfate).
