Product range

The reverse osmosis membrane launched by the company includes ultra-low pressure reverse osmosis membrane element, low pressure high desalination rate reverse osmosis membrane element, brackish water desalination membrane element, high-pressure anti-pollution membrane element, seawater desalination membrane element and home machine membrane element, totaling six series of nearly 30 varieties.


8040 Low Pressure Reverse Osmosis Membrane


Adopted technology

Reverse osmosis is currently the most fine filtration technology. Reverse osmosis membrane can block all the dissolved inorganic molecules and any relative molecular mass greater than 100 organic matter, water molecules can pass through the membrane to become pure water. The removal rate of divalent ions in water can reach up to 99.5%, and the removal rate of monovalent ions is also above 95%.


Application scope

Reverse osmosis membrane is widely used in the preparation of space water, pure water, ultrapure water; alcohol manufacturing and beverage production water; pharmaceutical, electronics and other industries in the pre-preparation of water; chemical processes in the concentration of water, separation, purification and preparation of pure water; boiler make-up water desalination and softening; seawater, brackish water desalination; papermaking, electroplating, printing and dyeing and other industrial water, water and industrial wastewater reuse.
