Product Desciption

BW Series RO Membrane Elements

Brackish Water (BW) Series include 8-inch membrane elements and 4-inch ones. This series of membrane element have larger effective filtration area, and wider inflow path. Not only does it increase the water yield, but diminish the frequency of cleaning, saving energy and cost. BW series obtain the highest quality of water at the lowest cost .
BW series membrane elements are suitable for desalination of surface water, underground water and low-pollution water source with TDS < 6000ppm and mainly applied in pure water, in food and pharmaceuticals industry, desalted water in power station, boiler feed water , filtering feed water system and purification system of river and under-ground water.
