RO Membrane Elements
FilmTec Corporation is a subsidiary of The Dow Chemical Company and part of the Dow Water Solutions business. they make high-quality reverse osmosis and nanofiltration elements for a wide variety of industrial, municipal, commercial and home drinking water applications.
RO Membrane elements, which have an unsurpassed high-active membrane surface area
that produces 99.5 percent or greater typical salt rejection performance.
Low-energy brackish water elements, which are designed specifically to meet emerging
demand for lower-pressure RO system operation; these elements help reduce operating expense
without sacrificing salt rejection or high productivity. Reverse osmosis membrane elements that
are installed before ion exchange beds, which help reduce demineralizer operating costs
dramatically; pretreating water for boiler makeup with these elements removes silica, dissolved
solids, and total organic carbon (TOC), extending the life of the resins and lowering chemical
regeneration usage, waste handling, and maintenance costs. Reverse osmosis membrane
elements that are used in double-pass RO systems, which produce high-purity water in a
continuous process; for applications with less stringent water-purity requirements, these
elements can be used cost-effectively in single-pass RO systems as well.
