Document Type and Number:
WIPO Patent Application WO/2017/128598
Kind Code:
A1
Abstract:
Provided are a seawater desalination method and a seawater desalination system. The seawater desalination method comprises four steps, i.e., filtration for impurity removal, filtration for oil removal, pressurization and adsorption for oil removal, and electrodialysis desalination. The seawater desalination system comprises a booster pump (6), a seawater impurity-removing filter (1), a seawater oil-removing filter (2), a seawater adsorption oil-removing filter (3), a vortex generator (4) and an electrodialysis seawater desalination device (5). The seawater desalination method and system reduce the energy consumption by 60-70% with respect to the prior art, and the oil-bearing concentration of treated seawater is ≤ 2 ppm. The seawater desalination method and system are applicable to islands and vessels.
