Volatile Fatty Acids Production from Codigestion of Food Waste and Sewage Sludge Based on β-Cyclodextrins and Alkaline Treatments

Figure 3

Effects of alkaline pH 10, β-CD addition, and combined treatment on VFAs production from codigestion of FW and SS (3 : 2). The pH control was divided into initial pH 10 adjustment (ini pH = 10) and constant pH 10 adjustment (cons pH = 10). The β-CD dosage was 0.2 g/g total solid (TS).
