Brackish Water
Dow Water & Process Solutions' (DW&PS) FILMTEC™ Membranes Provide High-Performing, Quality Elements to Drive Real-World Business Value in Industrial Water Production from Brackish Sources
FILMTEC Brackish Water Elements Offer Various Strategies to Lower Your Cost to Purify Water
Whether you seek the latest high performing and innovative solution or the most cost effective one, our brackish water product line offers the optimal balance of performance, quality, reliability, and cost. New FILMTEC™ products, technologies, and strategies for improving the reliable operation of your Reverse Osmosis (RO) water treatment system, can help you lower the total cost of water treatment. DOW™ FILMTEC™ elements can facilitate maximized system output, improved pure water quality and extended useful element life in your RO water treatment system, and our elements are more durable and clean more effectively over the widest pH range (1-13) than other (RO) elements.
FILMTEC™ high rejection brackish water elements have the highest rejection of solutes critical to the reliable performance of a high-purity water treatment system, including silica, boron, sulfates and ammonium, made possible by the latest innovations in thin film composite membrane chemistry.
Advanced membrane polyamide chemistry, enables the highest biological and organic fouling resistance, and is combined with an optimized 34 mil feed spacer design that resists the formation of fouling and reduces pressure drop across the element.
Low energy FILMTEC™ elements enable operational cost savings through reduced energy usage and higher system productivity than other elements.
Higher surface area elements, combined with a 28 or 34 mil feed spacer, permit RO system designs that meet productivity targets with fewer elements, and lower energy consumption.
Introducing the Latest Additions to the FILMTEC Product Line
-
The
DOW™ FILMTEC™ BW30HR-440i is designed to significantly improve the permeate water quality and productivity of your reverse osmosis (RO) water treatment system. Developed by DW&PS' industry research team, the BW30HR membrane sheet sets the new standard for the rejection of solutes critical to the performance of your RO system, including silica, boron, ammonium, nitrates and phosphates. Combine that with the highest guaranteed
active membrane area (100KB PDF) (440 ft
2) and the industry's most robust element construction, the BW30HR-440
i delivers outstanding performance over the entire life of the RO element.
-
Intended for feed water that has a high potential for biological or organic fouling, the DOW FILMTEC BW30XFR-400/34
i element can reduce the cleaning frequency, and improve permeate water quality, of your reverse osmosis (RO) water treatment system. Another advancement from DW&PS' research team, the BW30XFR membrane sheet has unique polymer chemistry, developed to resist biological and organic fouling. The BW30XFR-400/34
i offers a unique combination of high
active area (100KB PDF) (400 ft
2), and a new 34 mil spacer, optimized to resist fouling formation, enabling trouble-free operation and lower maintenance costs on challenging feed streams.
-
All new elements incorporate
iLEC™ interlocking endcaps, an innovative element-coupling technology that minimizes the risk of o-ring leaks that lead to degraded water quality.
