A type of ultra-low pressure with the molecular cutoff of 100~500 Dalton, and the soluble inorganic salt passes selectively.

Membrane Properties

  • Stable performance
  • Low operational pressure
  • High product water
  • Excellent molecular cutting off 
  • Outstanding contaminant resistance
  • Appropriate rejection
  • High COD removal
