LANXESS’ Lewabrane® ULP line is available in both 4×40- and 8×40-inch (10.1- and 20.3-cm x 101.6-cm) membrane elements. Eight-inch ULP elements are available with a 400-square-foot (37.1-square meter) membrane, with an innovative 34-mm spacer using alternating strand design (ASD) geometry, as well as a 440-square-foot (40.8-square meter) membrane with a 28-mm spacer. All ULP membranes are wet-tested and supported with a signed CoA. This product line offers high water permeability and high micropollutant rejection at low operating pressures. These membranes typically require 40 percent less operational pressure than standard pressure membranes (typically tested at 225 psi and 2,000 ppm NaCl).
