Filmtec BW30-400 RO Membrane
DOW Filmtec BW30-400 RO Membrane 10500 GPD, an 8″ x 40″ high productivity brackish water Reverse Osmosis Membrane that can provide RO quality water up to 10,500 gallons per day at a 15% recovery rate. It can operate at feed pressures ranging from 225 psi to 600 psi with 99.5% salt rejection. This element offers the highest quality water for large-scale industrial and municipal water treatment systems purifying greater than approximately 10 gpm (2300 L/h) of RO water and is the industry standard for reliable operation and production of the highest quality water in commercial applications. It was the first 400 square foot membrane elements on the market and continues to be widely used in new equipment and retrofits where system capital and productivity are factors.
These elements are ideal for reverse osmosis plant managers and operators dealing with controlled pre-treatment and seeking consistent, high performance, long element life and increased productivity.
Filmtec elements can separate salts from water and are produced with an automated fabrication process for precision, consistency, and reliability offering high rejection of dissolved solids and organics and operate very efficiently at lower pressures. This minimizes equipment CAPEX in designs with savings in elements and pumping due to the 400 ft² active area while delivering the most effective cleaning performance, robustness and durability due to its widest cleaning pH range (1-13) tolerance. The 400 square feet(41 square meters) of active membrane area, gives system designers the option of designing a system with fewer membrane elements, requiring lower capital expenditures for membranes and components. This element is widely used in industrial water demineralization, production of municipal drinking water and water reuse.
