Seawater Desalination Reverse Osmosis(RO) Treatment System

Reverse osmosis seawater desalination equipment is the principle of reverse osmosis technology to desalinate seawater for the device. There are portable, boat desalination equipment and large seawater treatment equipment. Production capacity: 500L/D–100T/D.

Products Detail:

Reverse osmosis seawater desalination technology is a mature and stable comprehensive new technology with high water quality. Reverse osmosis membrane can remove bacteria, viruses, metal ions, and other harmful substances in seawater, and make the content of TDS from 45000 mg/L up and down to about 200 mg/L, its salt content is greatly reduced, the water quality after desalination is even better than tap water, so it can be used for industry, commerce, residents and ships, ships.
