Two phase anaerobic organic matter treatment and system

摘要

The process and system may have an organic matter influent introduced into an acid reactor. The acid reactor may be maintained under conditions to facilitate creation of volatile acids in a fluid having water and suspended solids forming a sludge effluent. The sludge effluent may be communicated to an acid separation element where the water and volatile acids may be separated from the suspended solids. A liquid stream may be communicated from the acid separation element to a methane reactor and a solids recycle stream may be communicated to the acid reactor. The methane reactor may be maintained under conditions to facilitate creation of biogas. A liquid effluent may be communicated from the methane reactor to a methane separation element where liquid water may be separated from the solids. A second solids recycle may be communicated from the methane separation element to the methane reactor.
