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
