Abstract
A beneficiated sludge solids composition comprising digested municipal sewage sludge, ammonium sulfate, and superphosphoric acid. Alternatively, a beneficiated sludge solids composition comprising digested municipal sewage sludge, ammonium sulfate, mineral acid and phosphate salt. The constituents of the beneficiated sludge solids composition of the invention act synergistically to increase economic value through increased fertilization values of nitrogen and phosphorous, decreased flammability and autocombustibility, decreased ammonia evolution on drying and decreased corrosibility. The beneficiated sludge solids composition is capable of being produced in present sewage treatment facilities.
