Filmtec

FILMTEC BW30 PRO-2540 Elements are an industry standard for reliable operation and production of high quality water. They are designed for systems smaller than 1 gpm (0.2 m3/h). DuPont FilmTec(Formerly DOW FILMTEC) BW30 PRO-2540 elements offer a hard shell exterior for extra strength and may be cleaned over a wide pH range (pH 1-13) for the most effective cleaning.

FILMTEC Brackish Water Reverse Osmosis Elements can separate salts from water and are produced with an automated fabrication process for precision, consistency, and reliability. FILMTEC RO membranes build on a tradition of leadership in the thin-film composite membrane industry and meet the challenges of higher rejection in lower-pressure operations.

Description

FilmTec Seamaxx–440i Elements are the choice for seawater systems operating at low to medium levels of salinity and temperature, as well as for brackish water with relatively high salinity. The element’s flowrate is significantly above flowrates of any other SWRO element currently available in the market. This extraordinary high element productivity leads to substantial savings, primarily in energy consumption when compared to conventional low-energy SWRO products. In addition, FilmTec™ Seamaxx™–440i includes the typical FilmTec™ Element features:

    The 28-mil feed spacer combines low differential pressure with low cleaning frequency and high cleaning efficiency.
    The renowned iLEC™ Interlocking Endcaps help to reduce system operating costs and the risk of O-ring leaks.
    The oxidative-free membrane manufacturing process results in high membrane robustness and long-term stable performance.
    The widest pH range for cleanings (pH 1 – 13) allows effective cleanings even in cases of severe fouling.
    The automated, precision fabrication gives a greater number of shorter membrane leaves thus reducing fouling while maximizing element efficiency.

DOW Filmtec BW30HR-440i RO Membrane 12650 GPD, a 8" x 40" high rejection brackish water Reverse Osmosis Membrane with iLEC(tm) Interlocking Endcaps that can provide RO quality water up to 12,650 gallons per day at a 15% recovery rate. It can operate at feed pressures ranging from 225 psi to 600 psi with 99.7% salt rejection. It has a 440 ft² active area that delivers the highest quality permeate water while minimizing CAPEX and OPEX. This element offers the the most effective cleaning performance 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 RO water in commercial applications. These elements are ideal for reverse osmosis plant managers and operators dealing with controlled pre-treatment waters and seeking consistency, high performance, long element life, increase productivity, higher water quality coupled with excellent fouling resistance and reduced footprint installations.
