Design a primary anaerobic digester using data.
Input data:
• Population: 67,000 inhabitants
• Average influent flow: Q = 9,820 m3/d
• Influent SS load: 3,720 kg/d
• Influent SS concentration: SS = 379 mg/L
• SS removal efficiency in the primary clarifier: 60% (assumed • Mixed sludge load to digester: 3,307 kgTS/d
• Influent sludge flow: Q = 64.2 m3/d
• VS/TS ratio = 0.77
Requirements:
(a) Digester volume
(b) Hydraulic detention time
(c) Primary digester effluent sludge (influent sludge to secondary digester) (d) Heat balance in digester
Design a primary anaerobic digester using data. Input data: • Population: 67,000 inhabitants • Average influent flow: Q
