Digester Volume
125 m³
Biogas Output
3.67 m³/day
Electric Capacity0.32 kW
How to Use This Calculator
- Enter the daily feedstock volume in m³/day (total organic material entering the digester each day).
- Set the hydraulic retention time in days — 20–30 days is typical for mesophilic operation.
- Choose the operating temperature: ~37°C for mesophilic, ~55°C for thermophilic.
- Review Digester Volume (m³) to size your tank, Biogas Output (m³/day), and Electric Capacity (kW).
- Use the bar chart to compare digester volume, daily biogas, and electricity output side by side.
