Ion Exchange Resins and Membranes




Skilled chemical components organisation LANXESS is exhibiting ion substitution resins from its tested Lewatit wide range and its Lewabrane turn around osmosis membranes at the Singapore International H2o Week (SIWW) to be held from 2 – 4 June 2014 in Singapore.

Alexander Scheffler , director of Membrane Business in LANXESS' Liquid Purification Technologies business division , stated : "The Asian trade is simply becoming the single most useful markets for our turn osmosis membranes and we proudly provide our latest progression for seawater desalination membranes . The latest seawater membranes have probably always been suffering huge lead testing in Egypt.”

Asean's water issues


Indonesia and Thailand have always been reliant on natural resources like the groundwater extraction – which often can result in ‘sinking' or subsidence . Around 40% of Jakarta is below ocean level – this problem is deteriorated by Indonesia's forecasted people enlargement of approximately 60% within the next 20 years, which will only boost h2o in take demands.

The other hand, water-scarce Singapore, which imported h2o from Malaysia for many years, has tactically manufactured its h2o treatment area.


Among the major changes has been the opening of seawater desalination modern technology. It is the home of among Asia's greatest seawater desalination plant, and it is projected that desalinated water will meets to 25% of Singapore's h2o need by 2060, focusing its importance for years to come.

A spiral injury membrane is break to extent for a inverted osmosis component. The proportions of the Lewabrane units from LANXESS suit with the ones quality items, which suggest that they could be easily established in the quality pressure containers of reverse osmosis plants.

The Lewabrane membrane break-up parts made at the Bitterfeld site in Germany for reverse osmosis (RO) are specially improved by LANXESS for commercial h2o medication and the treatment of drinking water. The wide variety recently contains materials for the desalination of brackish and low-salinity waters. Important facets of application consist of the manufacturing of boiler feed water, wastewater medication, groundwater remediation and full demineralization for microchip fabrication.

Almost all Lewabrane membrane factors fulfill NSF/ANSI Quality 61 for the health related implications of drinking water process material. The U .S. National Sanitation Foundation (NSF International) has guaranteed all of that membrane elements currently issued by LANXESS are safe for use in the therapy of drinking water, a business section with strong enhancement potential.

Lewatit is the leading product in the area of ion exchange resins. LANXESS markets some 200 varied product grades for various companies and applications. A mixture with the company's membrane parting items is feasible, depending upon the limits of a certain application. While membrane technology is very cost-effective for water with a big salt content, only ion exchange resins (IEX) can clean water with less salt amounts to the point where only trace amounts remain. With both methods connected in series, water of the highest purity can be produced even from very poor-quality water.

State-of-the-art membrane separation elements of LANXESS' Lewabrane range for industrial water treatment and the treatment of drinking water.

Scheffler added : "Our service contain assistance with plant design , encompassing both applications development and the economic and ecological aspects ."
