PSI MEMBRANE® Pro-SW-HR seawater RO membrane,incorporated with innovative Thin Film Nanocomposite(TFN) technology, reduce the cost of desalination while delivering superior water quality. Provide industry leading salt rejection suitable for high salinity seawater applications.
- Produce 30% more flow:TFN Leading technology cable to produce 30% more flow than conventional TFC membrane.
- High rejection rate 99.85%:TFN innovated technology on surface guarantee excellent salt-rejection with lower pressures .
- Less Cleaning Frequency:TFN membrane outstanding anti-fouling performance is greatly reduce microorganisms and inorganic pollution contribute to less cleaning frequency .
- Wide Cleaning pH(1-13) Range:Provides the most effective cleaning performance, robustness and durability due to its widest cleaning pH range and chemical tolerance.
