The membrane elements were recently tested for several months in desalination plants on the Red Sea in Egypt.

Claus Mertes, MD of Deutsche MeerwasserEntsalzung  GmbH, a company contracted by LANXESS to conduct the tests, presented the results at the SIWW in his presentation, “SWRO Membrane Performance – Pilot Plant Test Egypt.”

He reported that the new Lewabrane RO S elements meet or exceed the relevant industrial standards in continuous operation (24/7) under real conditions. They showed high salt rejection under fluctuating temperatures, salt contents and pH values. 

The product range incorporates three different elements with high rejection rates (HR): Lewabrane RO S400 HR, S440 HR and S085 HR 4040. The first two are 1,016 mm (40 in) long with a diameter of 201 mm (8 in), and have a membrane area of 400 and 440 ft2, suitable for use in all standard RO facilities. The third grade has a diameter of 101 mm (4 in) and is suitable for smaller systems.
