Designed to purify water with high biological or organic fouling potential in systems with well-controlled pretreatment, DOW FILMTEC™ BW30FR-400 reverse osmosis elements incorporate Dow's proprietary FR (fouling resistant) membrane technology that provides excellent fouling resistance and cleanability. This product is an extension of the DOW FILMTEC BW30FR-365 element that has demonstrated its value for numerous customers around the world. The BW30FR-400 element features:
High active area (400 square feet) for more productivity without increasing the operating flux.
High rejection DOW FILMTEC RO membrane that has a wide pH cleaning range (pH 1-13) that allows for effective cleaning of scale, organic compounds, and biofilm.
Automated, precision fabrication with a greater number of shorter membrane leaves, reduces the overall effect of fouling and maximizes membrane efficiency.
These features offer system operators some of the best long-term economics and most trouble-free operation for RO membrane purification of fouling water.
