DEVELOPMENT OF A NOVEL ENZYME BIOFILM METHOD FOR TREATING WASTEWATER FROM FOODS CONTAINING HIGH CONCENTRATION OF FOG

Abstract

Wastewater from foods containing high-FOG is generally treated using a DAF method alone or a DAF and activated sludge method. However, these methods are often associated with problems related to operation, management, and cost. Research and development of a new, practical treatment method is needed. This study aims to develop an enzyme lipase biofilm method EBM to replace DAF, DAF + activated sludge by combining EBM for treating wastewater from high-FOG foods. We evaluated the practical implementation of the EBM by running the system on a long-term basis at a facility for treating wastewater from high-FOG foods.
