ABSTRACT:
Apparatus for treating wastewater includes a settling tank, a sludge digester and a holding tank. Solids from the settling tank are delivered uniformly throughout the seed sludge in the digester and combustible gas is drawn off the top. Sludge from the digester is delivered to the holding tank where further combustible gas evolves and is removed for other uses. The sludge from the holding tank is recycled through the digester or discharged from the system for drying and/or subsequent use.
