Abstract The analysis of 18 months of early operation for a channel aeration activated sludge wastewater treatment plant is presented. The treatment plant receives an average flow of 2.8 million gallons per day from the John Morrell and Company, Ottumwa, Iowa hog and beef meatpacking plant. The treatment plant includes preaeration, primary settling and grease removal followed by two 3.5 million gallon aeration channels (40 by 6 feet deep by 1,050 feet in length) in parallel. Rotor and floating aerators are utilized. One channel utilizes an experimental straightline settling unit (16 by 475 by 6 feet deep). The design and operation of the primary treatment units was inadequate. Tubular conveyors for sludge removal were not satisfactory. More efficient grease and suspended solids removal is needed prior to the aeration process. The channel aeration activated sludge process is capable of achieving organic removals of 90 to 95 percent from meatpacking wastewater. High effluent ammonia levels are of concern. Various plant design changes are needed to improve the consistency of good effluent quality.
