  • Which aeration system is used in MBBR IFAS?
  • Coarse- or fine-bubble aeration systems are used in the MBBR IFAS proc … With the MBBR IFAS (moving bed biofilm reactor integrated fixed-film activated sludge) process, the biomass required for biological wastewater treatment is either suspended or fixed on free-moving plastic carriers in the reactor.
  • What is MBBR IFAS?
  • With the MBBR IFAS (moving bed biofilm reactor integrated fixed-film activated sludge) process, the biomass required for biological wastewater treatment is either suspended or fixed on free-moving plastic carriers in the reactor.

  • Are MBBR and IFAS wastewater treatment plants a problem?
  • The design and engineering of MBBR and IFAS wastewater treatment plants is full of obstacles and mistakes made can be hard to remedy. Problems can arise when unexperienced plant construction companies and plastic manufacturers without any process-technological knowledge try to copy this technology.
  • Do coarse-bubble aeration systems improve oxygen transfer efficiency in MBBR IFAS process?
  • Coarse- or fine-bubble aeration systems are used in the MBBR IFAS process. In this study, the oxygen transfer efficiency (OTE) of a coarse-bubble aeration system was improved significantly by the addition of the investigated carriers, even in-process (∼1% per vol-% of added carrier material).
