This study was performed to evaluate reduction of sewage sludge by thermal hydrolysis process. Sewage sludge(moisture content 80%) was heated direct heating by steam in 200℃, 20bar for 1hour. Effluent of thermal hydrolysis was filtered through membrane filter press(pore size 3㎛) and measured moisture content. The results of study show 52% of moisture content after thermal hydrolysis and 41% reduction of sewage sludge. |
