a) Design a continuous flow anaerobic digester process for a PE 50 000 plant that treats municipal wastewater sludge. Sludge solid contribution is 0,13 kg of dry solids per PE a day and the volatile content of the sludge is 80%. The dry solid content of the digested sludge is 8% and effluent flow rate 46 m3/d. Use an organic loading rate of 4 kgVS/m3d. Calculate the reactor volume, HRT and SRT. b) Using Buswells equation calculate the methane potential of glucose (g of methane/g of glucose).
