Thermal power plant boiler make-up water and semiconductor chip cleaning ultrapure water put forward extremely strict requirements on silica, heavy metal and TOC removal performance of RO membrane. Ordinary low-flux membrane elements cannot effectively intercept silicon dioxide, which is easy to form hard scale on boiler tubes and precision electronic equipment, increasing equipment failure rate. Our standard LF-BW brackish water RO membrane adopts high-density polyamide separation layer, the interception rate of SiO2 is higher than 98%, the overall stable salt rejection rate reaches 99.7%, and the single membrane area is up to 440 square feet, which can realize large-volume stable water production under medium pressure working conditions. It is the mainstream standard RO membrane for two-stage RO + EDI ultrapure water system in power and electronics industries.
Complete specifications of LF-BW RO membrane and matched industrial UF membrane modules are displayed in our water filter element series.
