An RO spiral-wound element is a filter comprised of different layers. It contains membrane, feed spacer and permeate sheets rolled up around a product collection tube. Conwed feed spacers hide inside RO spiral-wound elements and provide the necessary gap between membrane and permeate layers to promote turbulence of the feed stream. “Until now, most of the reverse osmosis innovation has come from membrane developers but we believe the next wave of innovation will come from the feed spacer”, said Ivan Soltero, Strategic Marketing Manager at Conwed.
