<p>PROBLEM TO BE SOLVED: To provide a reverse osmotic method seawater desaltinating system capable of keeping a water producing performance even if an injection of a flocculant and sand filtration, etc., at a pretreating stage are eliminated. SOLUTION: In the reverse osmotic method seawater desaltinating system having the pretreating stage and a reverse osmotic membrane stage, the water producing performance is kept and stabilized even if the injection of the flocculant and the sand filtration at the pretreating stage are eliminated since the seawater intaken from a seawater layer of >=100m depth is used as a feed water to the reverse osmotic membrane.</p> |
