Description
Brackish Water (BW) Series RO membrane elements
Advantage
1.This series of membrane element have larger effective filtration area and wider inflow path.
2.Not only does it increase the water yield, but diminish the frequency of cleaning.
3. Low energy and cost to obtain the highest quality of water.
4. Can working for 2000-3000ppm feed water.
