To provide a seawater desalination system reducing the running cost as the whole system.
The seawater desalination system includes a heat exchanger 12 which is disposed on upstream side of reverse osmosis membranes and heat-exchanges between a medium and seawater of lower temperature than the medium, a power generation facility 16 using the medium cooled in the heat exchanger 12 as a cooling source, and a seawater desalination facility 14 desalinating the seawater heated in the heat exchanger 12 with the reverse osmosis membranes by pressurizing the seawater. The seawater desalination system also includes an evaporation type seawater desalination facility 46 desalinating the seawater by the evaporation method, a reverse osmosis membrane type seawater desalination facility 48 desalinating the seawater with the reverse osmosis membrane method, a power generation facility 16 generating waste heat through the power generation, a waste heat allocating facility 50 allocating the waste heat to the evaporation type seawater desalination facility 46 and reverse osmosis membrane type seawater desalination facility 48, and an allocation amount operation part 42 obtaining the allocation amount of the waste heat based on the amounts of demand of the fresh water and power.
