BW30XHR PRO-400/34i DuPont FilmTec™ 11,500 GPD at 225 PSI 8 x 40 inch 99.8% Rejection Membranes

DuPont FilmTec BW30XHR PRO-400/34i Extra High Rejection Brackish Water RO Membrane (11,500 GPD)

For rigorous municipal water purification and highly demanding industrial demineralization operations, achieving the absolute highest level of permeate quality is a necessity. The DuPont FilmTec BW30XHR PRO-400/34i is a commercial-grade, extra high rejection brackish water reverse osmosis (RO) membrane engineered precisely to meet these exacting standards. Designed to process challenging feed waters in applications such as power generation, steel manufacturing, and petrochemical production, this element delivers exceptional targeted rejection of tough contaminants including silica, boron, nitrate, TOC (Total Organic Carbon), and ammonium. Built for continuous heavy-duty operation, it ensures a highly stable, long-term flow of ultra-pure water while maximizing overall system durability.

Engineered to optimize both productivity and operational efficiency, this membrane features an expansive 400 square feet of active surface area and utilizes an advanced 34-mil low differential pressure (LDP) feed spacer to significantly enhance fouling protection. A key feature of the PRO series is the integration of proprietary iLEC (Interlocking End Caps), which securely connect elements within the pressure vessel to reduce system operating costs and eliminate the risk of O-ring leaks that compromise water quality. Operating efficiently at a standard applied test pressure of 225 PSI, the element delivers a robust permeate flow rate of 11,500 gallons per day (GPD) alongside an outstanding stabilized salt rejection rate of 99.8%.
