Patent ID: 8197693

Claim:
A process for producing electricity, comprising; heating a sea water using solar energy to 60° C. to produce a heated sea water; pumping the heated sea water to an aeration system as a feed stream to remove a precipitate as a soluble contaminant as a pretreatment of the sea water to form a secondary sea water for further processing; filtering the secondary sea water to remove a contaminant and to reduce a fouling, using at least one of a regular filter and a ceramic filter; distilling the filtered secondary sea water using a membrane distillation system to produce a distillate water; performing pressure retarded osmosis to further desalinate the distillate water to produce a zero brine water; collecting the distillate water and the zero brine water that is desalinated in a distillate tank for human consumption; generating an electricity using a pressurized diluted brine produced by the pressure retarded osmosis system and removing the contaminant using a crystallizer and recirculating the diluted brine to the membrane distillation system and reducing the volume of diluted brine to be disposed for the environment.
