Patent ID: 7749386

Claim:
A method of desalinating salty water comprising the steps of: inputting salty feed water to a desalination plant; using for a part of said salty feed water, salty water output from a cooling system of an electricity generating power plant, said salty water output being at a first temperature higher than an ambient temperature; using for another part of said salty feed water, salty water that is at a second temperature that is lower than said first temperature, said salty feed water retaining some heat acquired from said power plant when said salty feed water is received by said desalination plant; operating the desalination plant to desalinate said salty feed water; outputting a product water that is relatively less salt than said salty feed water from said desalination plant; outputting an unusable water that is relatively more salty than said salty feed water from said destination plant; and measuring the salinity of said salty water output from the cooling system of said power plant, measuring the salinity of said salty water that is at a second temperature, and adjusting the amount of said salty water output from the cooling system of said power plant and said salty water that is at a second temperature that is input to the desalination plant according to their relative salinities based on a preferred product water salinity level.
