500T/d Seawater Desalination Equipment

The seawater desalination system adopts the international advanced reverse osmosis technology and is designed by optimizing the system.


Applicable to cargo ships, oil tankers, offshore drilling platforms, islands, stations and coastal cities short of water.


The system can effectively remove inorganic salts, heavy metal ions, organic bacteria, bacteria and other harmful components in seawater, and desalinate seawater into high-quality water in accordance with the National drinking Water Sanitation Standard (GB5749-2022).


The whole system is equipped with advanced flow meter, pressure control instrument and safety pressure relief device, and is equipped with advanced detection and monitoring system to ensure stable operation of the system and high quality water production. When the water quality exceeds the warning salinity value, the system automatically opens and drains. Valves, which direct the production of water into the waste water line) and provide accurate values for the operation of the system.

Reverse Osmosis Technology

The reverse osmosis membrane is an artificial semipermeable membrane made of a semi-permeable membrane that has certain characteristics and is a core component of reverse osmosis technology.

The principle of reverse osmosis technology is to remove these substances and moisture according to the osmotic pressure of the solution, according to the fact that other substances cannot pass through the semipermeable membrane. The membrane pore size of the reverse osmosis membrane is very small, so that dissolved salts, colloids, microorganisms, organic matter, and the like in the water can be effectively removed.

The system has the advantages of good water quality, low energy consumption, no pollution, simple process and easy operation.
