Lanxess offers Lewabrane® Reverse Osmosis (RO) membrane elements for desalination and production of high quality water. The Lewabrane RO B090 HF 4040 product type consists of spiral-wound polyamide composite membranes with a surface area that exceed other commercially available elements by almost 6 percent. The bigger surface area results in higher water productivity and creates a superior permeate flow rate. HF (high flow) and HR (high rejection) membranes are available with surface areas of 370, 400 and 440 square feet. The high rejection versions offer more than 99.7% salt rejection measured under standard conditions.
