DOW FILMTEC™ BW30-365 Brackish Water Reverse Osmosis 8" Element
DOW FILTMEC BW30-365 Element is ideal for reverse osmosis plant managers and operators dealing with challenging water and seeking consistent, high performance and long element life. With decades of proven performance, DOW FILMTEC™ BW30-365 delivers high quality permeate water while minimizing unit cost. DOW FILMTEC BW30-365 also offers the most effective cleaning performance, robustness and durability due to its widest cleaning pH range (1-13) tolerance and the support of Dow technical representatives.
DOW FILMTEC Brackish Water Reverse Osmosis 8" Elements can separate salts from water and are produced with an automated fabrication process that ensures precision, consistency, and reliability. They are ideal for use in large-scale industrial and municipal water treatment systems that produce greater than approximately 10 gpm (2300 L/h) of permeate. Our RO membranes build on a tradition of leadership in the thin-film composite membrane industry and meet today's challenges for higher rejection using less energy and resisting foulants in challenging waters.
Dow inclucdes one coupler part number PV-IN810 (313198) with each element. Each coupler includes two 3-912 EPR o-rings.
DOW FILMTEC BW30-365 is FDA – 21 CFR 177.2550; Food and Drug Administration Compliant.
