Abstract:This study investigates the effect of microwave (MW) treatment on the disintegration of municipal activated sludge. Sludge samples underwent heating at a targeted temperature of 90°C for 35 minutes, with a 5-minute retention time. Soluble chemical oxygen demand (sCOD), sugars, proteins, nitrogen (N), and phosphorus (P) exhibited notable increases compared to untreated samples. Results indicate a substantial (42-45%) rise in methane production during the anaerobic digestion process of the disintegrated sludge c… Show more
