Equivalent RE8040-FEN 34 CSM reverse osmosis (RO) membrane element for brackish water and wastewater reuse

Introduction:

RO membrane, also known as reverse osmosis membrane, is one of the most precise membrane separation technologies in the field of water treatment. Its pore size is approximately 0.0001 μm, which is much smaller than the diameters of bacteria, viruses, and most ions.

It is driven by pressure difference and achieves efficient sieving and separation through semi-permeable membranes: under a pressure higher than the osmotic pressure of the solution, only water molecules can pass through, while most soluble salts, heavy metal ions, bacteria, viruses, antibiotics, organic substances, etc., which are harmful to the water, are almost completely retained. Thus, it achieves the purposes of water purification, desalination, and purification.

RO membrane can efficiently desalinate and is widely used in scenarios such as seawater desalination, brackish water purification, boiler pure water preparation, ultra-pure water production, municipal direct drinking water, and industrial wastewater reuse. It is the core component for preparing high-quality pure water and is also the most reliable technical choice for desalination and deep purification in current water purification systems.

Application:

Seawater desalination, brackish water purification, boiler pure water preparation, ultra-pure water production, municipal direct drinking water, and industrial wastewater reuse.
