Abstract Activated sludge from four municipal sewage plants was treated with 0-5% SO2 at pressures of 50-100 psig. The filterability of the treated sludges was improved and the treatment solubilized from 26 to 44% of the initial insoluble solids. The clear, light yellow filtrates were concentrated and then spray-dried to flowable, hygroscopic, tan powders having nutritional value as an animal feed supplement. Capital investment and manufacturing costs for a plant producing a 50% concentrate or dry product were estimated. Effects on reproductive performance of this organic feed concentrate (OFC) were investigated in rats, rabbits and chickens using nutritionally balanced diets.
