Hollow Fibre (HF) MBR membrane configuration | Polymeric membrane material


Low Energy No Aeration(LENA) Membrane Bio Reactor (MBR) offers advances in energy efficiency and membrane performance. It utilizes inertia force on membrane fibers via reciprocating motion as an alternative to the energy intensive air scouring process used in conventional MBRs.

Doosan LENA MBR has several additional benefits compared to conventional MBRs:

  • Eliminate air scouring system: No air scouring blower & associated equipment and less internal recirculation for nutrient removal (OPEX/CAPEX savings)
  • Membrane oscillation by reciprocation causes the fibers to move and creates inertia force on the fibers which provides more effective membrane fouling control compared to membrane air scouring
  • Prevent sludge accumulation within fibers due to the combined effect of reciprocating velocity coupled with pulsating inertia force on fibers
  • Also suitable for membrane filtration where it is necessary to maintain either anoxic or anaerobic conditions with less turbulence (e.g., Anaerobic MBR for methane recovery, Anoxic MBR for selenium, nitrate, sulfate removal in industrial wastewater).
