For 5 years specialty chemicals company LANXESS has been producing membrane filtration elements in Bitterfeld, Germany, in order to deliver ready-to-use elements for reverse osmosis purposes to customers worldwide. The building measuring around 4,000 square meters houses not only production and logistics facilities but also highly modern laboratories and offices. Photo: LANXESS AG

At the beginning of 2016, specialty chemicals company LANXESS launched a new, Lewabrane-brand reverse osmosis membrane element with improved performance on the market. Strands of different thickness are used for the novel, multifunctional feed spacers. These create space between the membrane surfaces for fast-flowing water, support the membrane in the process and cause turbulent water flow. The new product family is named after the alternating strand design (ASD). Photo: LANXESS AG

When finished, each single membrane element consists of a package with more than 20 pockets. This is assembled into a spiral wound element with a diameter of 20 centimeters and a length of one meter and then fixed. Photo: LANXESS AG

Ready for transport. LANXESS has been continuously expanding its line of membrane elements since production began in September 2011 and the products were introduced to the market in early 2012. Numerous types of elements are available in different sizes for treating brackish water and seawater and can be optimized to be particularly fouling-resistant or energy-efficient, or to deliver a high production output.

From Bitterfeld to the world: LANXESS supplies its RO membrane elements to the global market, which is growing by 10 percent every year. Among the important industrial applications for RO membranes are the treatment of process water for industrial applications and ultrapure water in the microelectronics sector. Lewabrane products reduce the saline and particle content in water and are frequently combined with ion exchange resins to achieve a highly efficient and productive demineralization system. Another area of application for Lewabrane is turning brackish water and seawater into drinking water. Photo: LANXESS AG

At its site in Bitterfeld, Germany, LANXESS manufactures ion exchange resins under the proven Lewatit brand for the global market. The plant produces monodisperse resins of the latest generation (gel and macroporous types) and is the most modern and largest of its kind worldwide. An area totaling 24,000 square meters incorporates production facilities, laboratories, logistics areas and offices. Photo: LANXESS AG
