Introduction:Filmtec membrane elements provide unmatched quality in separating the contaminants from concentrated water ending with purified clean water. These membrane filtration products are exceptionally efficient in water treatment applications that include industrial, commercial, municipal, and consumer-related concerns. Some of the most substantial and beneficial technologies such as reverse osmosis (RO) and nanofiltration (NF) have been put to use by FilmTec™ which not only have extremely high rejection capabilities, but utilize less energy to produce purified water than conventional elements
