Interpreting the synergistic effect in combined ultrasonication-ozonation sewage sludge pre-treatment [PDF]
, 2015 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 ( 500 kDa) were ...
