SEAWATER DESALINATION APPARATUS AND METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a seawater desalination apparatus by a membrane separation method and a method therefor removing TEP, preventing the clogging of a reverse osmosis membrane, and efficiently capable of stable working over a long period.SOLUTION: Provided is a seawater desalination apparatus comprising: a seawater taking part 10 of taking seawater; a flocculant adding means 15 of adding a flocculant to the taken seawater; a bubble generation and TEP-containing bubble removing part 20 of removing TEP components from the seawater including a flock formed the addition of the flocculant; a turbidity removing part 30 of removing a turbidity component from the seawater from which the TEP components are removed; and a reverse osmosis membrane treating part 40 of subjecting the seawater from which the turbidity component has been removed to desalting treatment so as to be desalinated.SELECTED DRAWING: Figure 2
