Staged Anaerobic Reactor
Staged Anaerobic Reactor
US Patent:
4568457, Feb 4, 1986
Filed:
Oct 31, 1983
Appl. No.:
6/546800
Inventors:
Richard A. Sullivan - Brookfield WI
Assignee:
Envirex Inc. - Waukesha WI
International Classification:
C02F 1104, C02F 328
US Classification:
210151
Abstract:
An industrial waste anaerobic digester is disclosed having separate sections therein, in which the acid forming and gas forming phases of the digestion process can occur separately under conditions optimized for each phase. A rotating biological contactor is provided in each section for increasing the liquid/gas interface to facilitate the anaerobic reaction. A series of partitions is provided in each section to create zones in which the waste concentration is extremely high and on which the biota can react at maximal reaction rates. The CO. sub. 2 produced in the acid forming phase is used in both acid and gas forming sections to mix and achieve pH adjustment, and the methane can be used in the gas forming sections for mixing. A thermophilic chamber in the center of the tank is surrounded by the mesophyllic chamber to minimize and utilize conductive heat loss.

Abstract:
An industrial waste anaerobic digestion process takes place in a digester having separate sections within the digester, in which the acid forming and gas forming phases of the digestion process can occur separately under conditions optimized for each phase. A rotating biological contactor is provided in each section for increasing the liquid/gas interface to facilitate the anaerobic reaction. A series of partitions is provided in each section to create zones in which the waste concentration is extremely high and on which the biota can react at maximal reaction rates.
