BW Series-Brackish Water RO Membranes UC BW-4040-82LE

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.

About this item

  • HIGH QUALITY MEMBRANE:Features highest flow rates available to meet the water demands of both land and sea based desalinates, offering a high efficiency while providing a superior quality of water for your household or business to consume and enjoy.

  • FRESH TASTING WATER:The Reverse Osmosis Replacement Membrane cleans your water by removing heavy metals, inorganics and volatile organics and other harmful chemicals that produce distasteful and smelly odors.
