<p>PROBLEM TO BE SOLVED: To provide an apparatus and a method for seawater desalination which allow energy saving of seawater desalination by raising the temperature of ocean deep water, while utilizing the low-temperature condition, and using as raw water for seawater desalination.SOLUTION: A seawater desalination apparatus 1 is provided with a surface water intake pipe 10 for taking surface sea water in and an intake pump 3 and an intake pipe 4 for taking ocean deep water in. The seawater desalination apparatus 1 also includes a turbidity removal installation 5, a first heating system 6, a second heating system 7, a high pressure pump 8 and a reverse osmosis membrane apparatus 9. The ocean deep water is heated by using as a medium (a coolant or a heat medium) in a power generation installation or an air conditioning installation 30 and heat-exchanging in the first heating system 6 and heated further by heat-exchanging in the second heating system 7 using surface sea water and the concentrated sea water of seawater desalination obtained by the reverse osmosis membrane apparatus 9.</p> |
