BioWater - Model CFAS - Combined Fixed Film Activated Sludge System (IFAS) Brochure

The Biowater CFAS (IFAS) utilizes the benefit of a traditional activated sludge process combined with a biological fixed-film system to create a highly efficient wastewater treatment plant in a much smaller footprint. The process begins with the introduction of polyethylene biomass carriers into the activated sludge. The activated sludge removes the majority of the BOD while the biofilm is allowed to grow in the protected biomass carrier. The biomass in turn oxidizes the ammonia. The Biowater CFAS (IFAS) is particularly well suited for retrofitting existing activated sludge plants to add nitrification as well as increasing the BOD removal in the same tank. The Biowater CFAS IFAS is also perfect for use in new construction.
