Significant progress in membrane technology in recent years has played a key role in making reverse osmosis a preferred solution for removing salt from all kinds of water. The treatment solution needs to be customized, since quality parameters of the feedwater and user requirements concerning treatment results and system performance differ. Capital and operating costs are key criteria in this regard. Our Lewabrane® product portfolio covers a wide range of specifications. This is a key prerequisite for achieving an optimized reverse osmosis process as a stand-alone system or in combination with Lewatit® ion exchange resins. It enables us to meet the requirements of very diverse water treatment applications, including:


  • Seawater desalination at municipal plants and industrial facilities
  • Production of boiler feedwater for water-steam circuits
  • Process water full demineralization and particle removal to produce ultrapure water
  • Decentralized water desalination in applications such as car washes, laundries, and ships
  • Groundwater remediation and recharging to obtain potable water
  • Industrial and municipal wastewater treatment


Benefits of Lewabrane® RO membrane elements include:


  • Optimized barrier layer chemistry for a high level cross-linking
  • Stable rejection of salt mixtures throughout their element lifetime, even with changing process parameters
  • Excellent organic compound rejection
  • Long service lives with consistently high performance levels
  • Lower biofouling thanks to enhanced feed channel flow
