FILMTEC SG30LE-400 Membrane Elements
Features
FILMTEC™ SG30LE-400 is a low energy element with high overall rejection and high rejection of lower molecular weight organic compounds and silica. It operates at low pressure to deliver energy savings. This element is intended for use in the roughing stage of UPW systems in both new equipment and replacement situations where lower energy cost is desired.
The new FILMTEC SG30LE-400 has an industry standard 1.125 inch ID permeate tube to facilitate element replacement.
