● Long service life: 15-20 years, rigorous process design to ensure long service life and low maintenance costs.
● The type of equipment combination can be realized: bracket type, armored type, brake type, container type, etc.

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.
