Figure 4: Comparison of COD solubilisation, protein and carbohydrate solubilization in untreated and hybrid (MW-H2O2) treated co-digestion (3:1- MWAS:FVW). sCOD/tCOD= ratio of soluble chemical oxygen demand to total chemical oxygen demand; sP/tP=ratio of soluble protein to total protein; sC/tC= ratio of soluble carbohydrate to total carbohydrate.
