Abstract

The effect of solid content on anaerobic digestion of dewatered sewage sludge under mesophilic (35°C) conditions were investigated using continuous digester. The experiments were carried out by changing the moisture content of dewatered sludge. The COD, TS and VS removal efficiencies were changed from 47.1% to 38.3%, 38.8% to 23.6% and 45.6% to 33.8% respectively, as the solid content increased from 3% to 11%. When the solid content of sludge fed to digester was higher than 8.9%, the carbohydrate removal efficiencies and methane production rates were decreased.
