Drying characteristics of wastewater sludge according to outside air inflow conditions

Year: 2018

Type: conference-paper

Abstract: The purpose of this study is to analyze the changes of drying efficiency according to the inflow conditions of outside air into the drying equipment during the drying process in order to reduce the energy used in the drying process of sludge. We conducted the experiment using a vertical thin film dryer. Materials used for the experiment are sewage sludge. As a result of the study, higher drying efficiency was obtained in the case of outside air inflow than in the case of no outside air inflow. In addition, optimum condition of outside air inflow was derived. Keywords: Drying; Sludge; Drying efficiency; Air inflow condition
