LIQUID PURIFICATION TECHNOLOGIES

Two ways, one goal – Clean water

The Liquid Purification Technologies business unit (LPT) is one of the world’s foremost suppliers of products for treating water and other liquid media. We hold a leading position in the development and production of ion exchange resins and are very active in our new business line for reverse osmosis membrane elements. We have production sites at our locations in Leverkusen and Bitterfeld, Germany, and in Jhagadia, India.

LEWABRANE® PREMIUM PRODUCTS FOR WATER TREATMENT

Lewabrane® RO membranes for state-of-the-art desalination of seawater, brackish waters, and low-salinity waters in industrial and potable water applications.

Performance advantages of Lewabrane® RO brackish water elements

  • Low salt passage, typically > 99.7% at standard conditions
  • High flow productivity
  • Improved barrier layer chemistry (lower charge and higher cross-linkage) providing lower membrane fouling rates
  • More stable salt rejection during operating lifetime (as the rejection mechanism is based more on solution diffusion than ionic repulsion)
