LANXESS announces the expansion of its RO membrane products with the Lewabrane RO ULP line, which has three product grades available immediately. They display higher water permeability, while offering the similar high level of rejection of critical substances. Operating pressure required in the pressure vessel is 40 percent lower, which reduces operating costs. These membranes are a good option for removing trace elements from wastewater and drinking water.
