Abstract

Electron beam was studied to enhance the biodegradability of sewage sludge. Changes in physicochemical characteristics of the sludge were examined with various irradiation doses, sludge thicknesses and exposure times. Irradiation thickness was suggested as the key factor affecting the efficiency of solublization of solid organic matter, whereas exposure time would be the most critical parameter in inducing cell lysis in sewage sludge. In addition, biogas production was improved as much as 22% when the sludge thickness was 0.5 cm with a dose of 7 kGy.
