Marine Sea Water Desalination System

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

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 marine sea water desalination equipment adopts reverse osmosis water treatment technology, and has been well received by many customers after many years of practical application.

The desalination equipment is mainly treated with domestic drinking water from boats, ships, offshore platforms and islands. The treated water can meet the national drinking water standards, and can be treated again to meet the national pure water standards.

Customer Cases

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.
