Sludge disinfection using electrical thermal treatment: The role of ohmic heating.Electrical heating has been proposed as a potential method for pathogen inactivation in human waste sludge, especially in decentralized wastewater treatment systems.  In this study, we investigated the heat production and E. coli inactivation in wastewater sludge using electrical thermal treatment.  However, DC power showed better performance in E. coli inactivation due to electrochemical inactivation in addition to thermal inactivation.
