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.
Claims36
A method for aerobically treating a low solids water-containing organic or sanitary waste which comprises combining said waste with a biologically inert, non-friable bulking agent characterized by having a substantial component with a density less than water to form a mixture, passing an oxygen-containing gas through said mixture to separate and remove excess water and form a high solids content reaction mixture, reacting said high solids content reaction mixture in the presence of an aerobic biomass under effective aerobic conditions to form a treated waste and an active biomass-coated bulking agent, separating at least a portion of said biomass-coated bulking agent from said treated waste, and recovering said treated waste from said reaction mixture.
