Abstract
Forty kilograms of pure cattle dung and cattle dung mixed with 10% digested slurry obtained from a field biogas plant was batch fermented in horizontal biogas digesters for 15 weeks under field conditions with mean ambient temperature 20-23°C. Compared to 821 l of biogas from digester I, containing cattle dung alone, 1457l of biogas was obtained from digester II, containing cattle dung mixed with 10% digested slurry. Mixing of slurry not only speed up the gas production but also enhanced its rate from 108 l/kg dry matter to 158 l/kg dry matter. It also resulted in 36.1% distraction of total volatile solid in digester II, compared to 23.93% observed in digester I. Mixing digested slurry is recommended for raising biogas production from cattle dung in dry fermenters.
