dc.description.abstractIn this study, it is aimed to optimize the anaerobic digestion (AD) system in which blast furnace slag (BFS) is used as an additive by using the response surface methodology (RSM). For this purpose, BFS ratio (0.5-3%), pH (5-9), and initial total solid (TS) (6-10%) were selected as input parameters and a model was successfully developed in RSM with Box-Behnken (BB) design for optimization of cumulative biogas production (mL), biogas yield (mL/g VS), CH4 content (%), volatile solids (VS) reduction (%), and chemical oxygen demand (COD) removal (%). Coefficient values (R-2) obtained from analysis of variance (ANOVA) were highly significant for cumulative biogas production, biogas yield, CH4 content, VS reduction, and COD removal as 0.94, 0.95, 0.96, 0.94, and 0.94, respectively. RSM results showed that optimum conditions for the maximum output values were obtained as 2.01%, 9 and 10% for BFS ratio, pH, and TS, respectively. Corresponding to these conditions, the maximum biogas production, biogas yield, CH4, VS reduction, and COD removal were 15,420 mL, 543.23 mL/g VS, 76.30%, 61.12%, and 70.85%, respectively.en_US
