Abstract of corresponding document: WO9418129
A wastewater treatment plant for removal of organic matter, suspended solids and other pollutants comprising a pre-treatment chamber (4), a biofilm-aeration chamber (7) and a settling chamber (16). Biofilm grows on the biofilm support structure (12), which is stationary and submerged in the mixed liquor of the biofilm aeration chamber. The combination of submerged or surface aeration and suspended solids particle size reduction occurs thereby creating a sufficient fluid flow within the biofilm aeration chamber. This combination results in the efficient digestion of organic matter and pollutants by the biofilm growing on the biofilm support structure submerged in the biofilm aeration chamber. This results in a vastly more effective digestion process that conventional processes producing no sludge. Furthermore, the resulting treated effluent has a high dissolved oxygen content and low BOD and suspended solids.
