Abstract
A method for aerobically treating water-containing organic wastes is provided. This process may be conducted in a closed reactor with suitable controls to prevent any adverse environmental impact, and involves mixing the wastes with an inert and non-friable bulking agent comprising a substantial component having a density less than water in the presence of an active biomass. An oxygen-containing gas is passed through the reaction mixture to assist in the removal of excess (free) water from the wastes to form a wetted high solids content reaction mixture containing the waste solids mixed in a bed of bulking agent. Effective aerobic reaction conditions are employed to convert the wastes to a treated waste.
