Proper management of excess sludge resulted from wastewater treatment through waste activated sludge process is a big challenge to wastewater treatment plant operators in order to comply with the stringent disposal regulation. To meet this objective with cobenefit of bioenergy recovery, anaerobic technology is a promising technique. However, anaerobic digestion in particular hydrolysis phase is a ratelimiting process which requires a long digestion time to fully stabilize the sludge. Therefore, a numbers of pretreatments are usually applied to shorten the digestion time requirement and to increase the digestion efficiency. In this study, pretreatments, e.g. ultrasound, chemical and combined chemicalultrasound were investigated for their effective sludge disintegration. Anaerobic digestion of pretreated sludge, subsequently, was conducted in order to evaluate the effects of pretreatments on digesters performance. In addition, a comparison of cost benefit analysis of anaerobic digesters with the pretreatment options was also presented in this study.
