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
