Biological Augmentation Eliminates grease and Oil in Bakery Wastewater

摘要

the feasibility of a biological augmentation approach to eliminate oil and grease in the wastewater of a large bakery was evaluated and experimentally tested. The approach, based on approximate of a treatment tank with a model of a continuous culture of bacteria (chemostat), was evaluated first. Bacteria appropriate for use in biological augmentation were selected according to theoretical requirements. Results of subsequent field tests corresponded fairly well to predicted values, although oil and grease content in the outflow was still greater than the allowable level.
