FILMTEC™ elements from Dow feature a spiral wound design and are based on the FT30 thin-film composite polyamide membrane, which has long been the industry standard for RO performance. The FILMTEC FT30 membrane consists of three layers: an ultra-thin polyamide barrier layer, a microporous polysulfone interlayer, and a high-strength polyester support web. The FT30 membrane has been continuously updated and refined to provide higher rejection, improved membrane flux, and low fouling performance. Today's FT30 membrane is uniquely uniform in performance and quality, without the taped or glued defects that can cause other membranes to fail.
Good understanding and execution of the basics of reverse osmosis can minimize troublesome and costly problems in the future. Consult these tools to get a detailed understanding of the effects of feed pressure and operation parameter changes on the performance of a membrane system.
iLEC™ Interlocking EndcapsVirtually Eliminate O-ring Leakage and Lower Your Energy Costs
Select FILMTECT brackish water and seawater reverse osmosis (RO) elements are now commercially available with iLECT interlocking endcaps, an innovative element coupling technology that significantly enhances the performance of RO systems.
Unlike sliding couplers, the decades-old connection method still used in most of today's advanced RO systems, the iLEC technology achieves a direct, leak-tight connection between adjacent element permeate tubes, reducing the number of sealing surfaces to a single, axially compressed o-ring. This patented design dramatically reduces the potential for seal leakage, enabling sustained higher quality permeate throughout the life of the elements, and reduces energy-consuming flow resistance, resulting in lower operating costs.
