BW Series-Brackish Water RO Membranes UC BW-8040-400FRLE

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

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.

Important Information

  • It is recommended that systems using these elements rinse the elements for 24 hours, prior to first use, to meet NSF/ANSI 58 Standard.

  • The first full tank of permeate must be discarded. Do not use this initial permeate for drinking water or food preparation.

  • Keep elements moist at all times after initial wetting.

  • To prevent biological growth during prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution. Rinse out the preservative before use.

  • The membrane shows some resistance to short-term attack by chlorine (hypochlorite). Continuous exposure, however, may damage the membrane and should be avoided.
