Introduced at the Membrane Technology Conference & Exposition (Feb. 1–5; San Antonio, Tex.), the reverse-osmosis (RO) elements from this company’s Lewabrane product line now feature a novel feed spacer used in the membrane element. The spacer provides for optimized flow in the RO element, resulting in lower energy consumption. Combining it with the Lewabrane RO membrane makes products suitable for numerous applications. Initially, two new products are to be introduced: Lewabrane B400 LE ASD and Lewabrane B400 FR ASD. Optimized for applications in brackish water, these elements have standard geometries (40-in. length, 8-in. dia.) and are characterized by very low energy consumption and high fouling resistance, says the company. — Lanxess AG, Cologne, Germany
