IFAS Wastewater Treatment System

IFAS (Integrated fixed film activated sludge) is a treatment process, combining suspended and sessile biomass. Equivalent to a conventional activated sludge process, necessary microorganisms for the biological treatment exist in sludge flakes that are suspended in the waste water. In addition a media is placed into the treatment tank in order to attach a part of the biomass (sessile biomass). With the attached growth more biomass is available in the system. More biomass simply means more microorganism and more micros are able to tackle more or higher polluted waste water.
