BW RO membrane elements are mainly used for brackish water desalination. They provide excellent, stable and consistent membrane performance for industrial water treatment systems.
The element operates under low pressure providing a more cost effective alternative for industrial-grade water treatment applications. It has high rejection rate for dissolved salts that are difficult to remove, such as TOC, SiO2, etc., and therefore, applicable to near zero discharge for oil and petrochemical industry waste water treatment and feed water for thermal power plant boilers. These RO membranes are available in 4"and 8" sizes.
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.
