Title:
SEAWATER DESALINATION METHOD AND SEAWATER DESALINATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/035397
Kind Code:
A1
Abstract:
This seawater desalination method is provided with a step for generating low concentration salt water having a salt concentration of 0.5 M or less by mixing biologically treated water obtained by biological treatment of organic wastewater (B) and seawater (A) and for filtering treatment that supplies the low concentration salt water to a reverse osmosis membrane device and a step for generating high concentration salt water having a salt concentration that exceeds 0.5 M by mixing the biologically treated water and seawater (A) or using only the seawater (A) and for filtering treatment that supplies the high concentration salt water to a reverse osmosis membrane device. A seawater desalination device (10) is provided with a mixing unit (16) constituted so as to be able to generate low concentration saltwater and generate high concentration saltwater and a reverse osmosis membrane devices that carry out filter treatment of the low concentration saltwater and high concentration saltwater obtained by the mixing unit (16).
