| Abstract |
The City of Erie, Pennsylvania and Hammermill Paper Company made a study of the joint treatment of domestic sewage and pulp and papermaking wastes. A pilot plant was constructed and operated in a series of controlled experiments. Supplemental studies were conducted in the Hammermill laboratories including the operation of a bench-scale activated sludge plant. It was demonstrated that a joint treatment plant could effectively treat a mixture of domestic sewage and pulp and paper mill wastes from Hammermill's Erie Division. A full-scale joint treatment plant obtained a BOD removal of approximately 80% in summer months and 90%-85% in winter months. Primary treatment achieved a 25% reduction in BOD and a 60% reduction in suspended solids. Treatment of mixed wastes by the activated sludge process required a long solids aeration period and a relatively low BOD to volatile solids loading to avoid high sludge volume indicies. (Author) |
