Abstract:
Hydrothermal treatment (HT) is a promising option for pretreatment of organic waste, due to its low energy consumption and contribution to increasing fuel energy density. HT has been also adopted as an energy effective method for dewatering. In this study, sewage sludge was treated in tubular reactor under hydrothermal condition over temperature range of 130−250 C under the fixed pressure of 5 MPa, and the final products which were liquid and solid were analyzed. The aim of this study was to investigate the behavior of organic matter in liquid phase during HT of sewage sludge by varying the temperature. The total organic carbon increased with temperature
