RO membrane(equivalent to filmtec LP4040)

RO membrane(equivalent to filmtec LP4040)
Product Detailed
BW low energy ro membrane; size:4040; area:80feet; applicable to the water <2000ppm salt; equivalent to filmtec LP4040.

BDX4040B-ULP low energy ro membrane is used for the desalination of low salinity water and other similar water and it has high desalination rate and long time stable performance under high flow and low operating pressure (fall 20-40% compared with common low pressure membrane).BDX4040B-ULP low pressure ro membrane is applicable to the water which contains less than 2000ppm salt. It is used to produce pure water or ultra pure water in electronics, power, petrochemical, food, beverage and pharmacy.
