Richard R Dague deceased, Largus T Angenent: Anaerobic migrating blanket reactor. Iowa State University Research Foundation, Henderson & Sturm, March 23, 1999: US05885460 (14 worldwide citation)

A continuously fed, compartmentalized reactor that reverses its flow in a horizontal manner. This system is developed without the requirement of elaborate gas-solids-separator and feed-distribution systems. Effluent recycling is not required, but mixing is necessary to obtain a sufficient biomass/su ...
