Submerged UF Membrane Filter (SUF)

Submerged UF Membrane Filter (SUF)

  • Small footprint, 40% less footprint than conventional membrane system
  • High separation efficiency, 30-60l/m2.h of water production without power, 60-120L/m2.h of negative pressure suction
  • The effluent quality is good, turbidity < 0.01 ntu
  • Low energy consumption, 0.01 kwh per ton of water and electricity 0.1
  • Wide application range of influent water quality, turbidity < 20ntu
  • Long lifespan is more than 5-8 years
  • Hollow fiber membrane with high strength and high separation precision; tensile Strength of membrane filament is 6-10n, average pore diameter is 0.03um
