The feasibility of using a complete mix activated sludge unit for secondary treatment of potato processing wastes was demonstrated. During the 1969-1970 processing season, both the activated sludge process and a flow through aeration process without secondary clarification were studied. The activated sludge unit was demonstrated to be capable of BOD removals, in excess of 90% over extended periods, with coliform removals in excess of 96%. With the flow through system, BOD removals ranged between 70 and 80%. Analysis of data obtained revealed that both the quantity of excess sludge produced and the amount of oxygen required were functions of the BOD removal rate and the mixed liquor volatile suspended solids concentration. The substrate removal rate coefficient was shown to be temperature dependent. The prevailing low air temperatures at the Shelley location did not cause system failure, but data obtained demonstrated the need to consider temperature loss in system design. Total annual treatment costs, excluding costs for waste activated sludge disposal, were estimated to be $.038 per lb BOD applied, and $0.21 per lb COD applied. Operation of thickener-clarifier on combinations of silt and biological solids was not successful. Failures with this unit demonstrated a need for the development of special silt removal and handling equipment for potato processing. (WRSIC abstract)
