Abstract
Official abstract text for this publication.
The subject invention provides advantageous systems and processes for anaerobic digestion of organic waste streams, particularly agricultural waste streams. According to this invention, a new process is provided in which a liquid fraction from an organic waste stream comprising soluble compounds is segregated and incubated in a reactor separate from the solids fraction of the organic waste stream. Digestion of waste in both reactors occurs substantially simultaneously and both reactors produce biogas (thus both reactors function essentially like single stage reactors but allow for continuous or intermittent loading). According to one aspect of the invention, at least one cross-flow baffle is provided for use in an anaerobic digester to collect biogas and break up clumped solids in the reactor. In another aspect of the invention, packing media for use in an anaerobic digester is provided.
First claim
Opening claim text (preview).
We claim: 1. A continuous feed anaerobic digester system for converting degradable solid waste feedstock into useful materials, wherein the system comprises: at least one single stage anaerobic reactor for treating a solid waste stream (SD reactor); at least one single-stage anaerobic reactor for treating soluble components in waste water separated from solid waste stream (AFR reactor); and at least one conduit connecting the SD reactor to the AFR reactor; wherein the SD rea…
