ABSTRACT:
A sludge digester is equipped with a network of pipes leading to several separate effluent ports distributed around the base of the digester near its walls. During use, sludge undergoing active digestion within the digester is withdrawn from the digester and forcefully pumped through at least one of said pipes to flush or sweep material tending to settle from less active regions of the digester into other regions undergoing active digestion, thus to prevent accumulations of sludge which is not actively consumed by bacteria.
