Description
Summary:The waste treatment system of a cooperative fruit processing cannery was studied for two operating seasons to determine treatment efficiency and to establish parameters for the treatment of liquid fruit processing wastes by aeration. The cannery, located in Yakima, Wash., processes pears, peaches, apples, and other fruits in lesser amounts. The facilities operate on a flow of 0.5 to 2.5 mgd (1,900 to 9,500 cu m/day) and up to 25,000 lb/day (11,000 kg/day) of BOD. The facility was operated with and without sludge recycle and with sludge reaeration. Data were collected on biological substrate assimilation, sludge growth, oxygen uptake, and sludge settleability. Constants were obtained for substrate removal, sludge growth rate, endogenous respiration, and oxygen requirements. Nutrient requirements and overall costs were recorded for presentation.
