This paper is concerned with the treatment of poultry wastes after the customary screening in flowaway systems and prior to discharge to a municipal sewer. The term 'pretreatment' will be used to cover all physical, chemical, or biological treatment provided for this purpose. The majority of poultry plants discharge to municipal sewers. A study shows that pretreatment at the poultry plant will eliminate the overload. The decision whether to pretreat or to go along with the municipal plant expansion program depends upon the relative annual cost of the two alternatives to the poultry plant operator. For example, suppose that excessive discharges of grease, feathers, or suspended matter are causing special problems in operating primary clarifiers and anaerobic sludge digestion at the municipal plant. The first step for correction of such problems is waste conservation at the poultry plant and attention to the flowaway system. The report makes recommendations and discusses corrective measures.
