LANXESS Lewabrane Brackish Water Reverse Osmosis Membranes

The Lewabrane RO membrane elements consists of spiral-wound, thin-film composite membrane elements for water treatment applications and optimized, low-cost operation for downstream unit applications, like separate-bed or mixed-bed ion exchange units.

Most important applications for industrial water treatment are:

  • Seawater desalination
  • Boiler feed water in power stations
  • Demineralization and particle removal
  • Water desalination for industries like car wash, laundries, and marine application
  • Wastewater treatment
  • Groundwater remediation and recharge

Lewabrane® benefits:

  • Low salt passage, typically >99,7% rejection at standard conditions in brackish water
  • 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)
    Improved organic compound rejection
  • More durable to allow less frequent, more aggressive cleaning
