Audited Supplier 8 Inch Reverse Osmosis Membrane for RO Water System with High Rejection Rate From Chinese Manufacturer
UltraClean BW reverse osmosis membrane elements are primarily used for brackish water desalination, providing excellent, stable and consistent membrane performance for industrial water treatment systems. The element operates at low pressure, providing a more cost-effective option for industrial-grade applications. For more difficult dissolved salts, such as TOC, SiO2, etc., it has a high removal rate. It is suitable for near-zero discharge of wastewater in the petroleum and petrochemical industries and boiler feed water in thermal power plants.
Product Highlights
1.High flux and high salt rejection
2.Low operating cost and good economic benefits

Stabilized salt rejection is generally achieved within 24-48 hours of continuous use; depending upon feedwater characteristics and operating conditions.
Reverse osmosis(RO) system
Reverse osmosis process is the world's advanced, energy-saving and effective separation technology now, with a filtration accuracy of 0.001 μm, to completely separate and remove all particles of soluble salts, colloids, organics, microorganisms, viruses,bacteria, rust, and heavy metals in water. It requires pressure to force pure water across a membrane, leaving the impurities behind.
However, note that reverse osmosis systems are not ideal for treating water that is very hard and/or with significant quantities of contaminants. In this case, to extend the operating life of the membrane, the water should be pre-treated before entering reverse osmosis membranes (filtering, deferrization, etc.).
