A heated low rate digester is used to digest 4000 lb dry solids/day, and 72% of the sludge solids are MLVSS. During the digestion, 65% of the MLVSS is digested (removed). The fresh sludge has 5% dry solids and the wet specific gravity is 1.01. The digested sludge has 7% dry solids and the wet specific gravity is 1.03. The digestion time is 30 days and 40 days of storage time is provided for the digested sludge. What is the digesting sludge volume per day?

The waste sludge production form a trickling filter plant is 12.5 m3/d containing 620 kg of solids (70% volatile). The proposed anaerobic digester design to stabilize this waste consists of two floating-cover heated tanks, each with a volume of 480 m3 when the covers are fully raised and a volume of 310 m3 with the covers resting on the landing brackets. (A) Calculate the digester volume per equivalent population with the covers fully raised. Assume 100 g of solids production...
