Abstract: An improved, multipass, horizontal rotating continuous feed digester provides an efficient aerobic digestion process for sewage, and which also reduces pollution. The improved digester promotes the ecology in that the gas and air feed and exhaust means are located at opposite ends of the digester. Moreover, the air and gas distribution means can be easily removed from the digester for inspection and cleaning.
