Home / Products / Reverse Osmosis Membrane Elements / Brackish Water (BW) / BWRO Membrane High Rejection Series BW-8040-400HR
BW RO membrane elements are mainly used for brackish water desalination. They provide excellent, stable and consistent membrane performance for industrial water treatment systems.
Product Description
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.
Membrane Features
Advanced membrane technology with innovative thin layer composite membrane design.
More consistent performance with less fouling requiring less frequent cleaning and change-outs.
100% dry-stored membrane maximizing shelf life.
