Two new Filmtec 8-in., salt-water reverse-osmosis (SWRO) membrane elements are now available. At 99.80%, the SW30XHR-400i has the highest salt rejection consistently demonstrated in the industry, claims the manufacturer. It also effectively removes boron and other dissolved solids to help plant operators meet stringent drinking water standards. The SW30Ule-400i elements have a flowrate of 10,000 gal/d with 99.7% salt rejection, and they are especially suitable for seawater desalination at low temperatures. Both elements are offered with iLEC interlocking caps that reduce pressure drop within the permeate tube, and help eliminate O-ring damage that can cause leakage in traditional desalination membrane systems. — Dow Water Solutions, Edina, Minn.
