FILMTEC™ reverse osmosis (RO) and nano-filtration (NF) elements are solutions for industrial, municipal, commercial and consumer water applications. These elements offer high rejection of dissolved solids and organics and operate very efficiently at lower pressures. FILMTEC elements also provide excellent structural stability and are more productive than other elements. These membranes are applied for de-mineralizing brackish water or desalinating seawater for a variety of industries and applications including industrial water treatment, power generation, food & beverage processing, municipal desalination and water reuse, and home drinking water devices.
