FILMTEC MEMBRANE

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.
