Industrial Water Filters SW-8040 Reverse Osmosis RO Membrane
BW series is a series of our WSD Commercial Membranes to achieve optimal flow and rejection rate stability, according to the situation. The membranes are also energy efficient and the diverse applications make them suitable for brackish water. The BW series is used in a variety of industries,such as pure water production, boiler feed water, food processing water, and pharmaceutical industry.
SW series is used for seawater desalination specifically which achieve optimal flow and rejection rate stability and boron removal rate.

It is recommended that systems using these elements rinse the elements for 24 hours, prior to first use. Permeate water obtained from the first hour of use should be discarded to the drain. To ease installation, it is recommended to use a lubricant safe for indirect water contact on all seals. 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 may damage the membrane and should be avoided.
