The sequential combination of ultrasonication and ozonation as sewage sludge treatment prior to anaerobic digestion was investigated. Synergistic volatile suspended solids (VSS) solubilization was observed when low energy ultrasonication (<12 kJ g−1 TS) was followed by ozonation. 0.048 g O3 g−1 T...
