Abstract

An anaerobic process for the digestion of organic wastes, and novel anaerobic digester. In digestion of the organic wastes in the presence of anaerobic microorganisms, at anaerobic conditions, the carbon:nitrogen and nitrogen:phosphorus ratios of the digestion are adjusted to optimize the rate of anaerobic digestion, generally only about 12 to 72 hours, or less, being required to produce a stabilized low solids sludge and clean liquid effluent. The anaerobic digester is designed to facilitate this process, and is transportable from site to site.
