Lewabrane RO products are produced in a modern, fully automated, state-of-the-art production facility in Bitter Feld (Germany). The chemistry approach for our RO membrane places the emphasis on higher cross-linking of the polyamide layer and, therefore, higher durability to cleaning chemicals, more stable rejection of mixed ion salt solutions and lower surface charge on the membrane to reduce the fouling tendency.
- Low salt passage, typically > 99,7% 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
