Abstract

A pilot scale anaerobic baffled reactor (ABR), for treating low-strength industrial wastewater (671.5±49.9 mg COD/L, 350.1-36.8 mg BOD5/L) was studied. The reactor was started with a hydraulic retention time (HRT) of 25 h and this was gradually reduced to 3.33 h. The best reactor performance was observed with an organic loading rate (OLR) of 4.45 g COD/L.d which was at HRT of 4 h and the COD removal efficiency was obtained up to 78.27% and majority of COD removal was occurred in the first compartment. Under these conditions, for prediction of the EFFLUENT SUBSTRATE CONCENTRATION (Se) and OPTIMUM VOLUME of the ABR (V), the Monod and Kincannon-Stover models were investigated. With using the Kincannon-Stover model, parameters of Umax and KB were obtained 2 and 2.14 g COD/L.d, respectively since, for the Monod model, the parameters of K and KS resulted as 1.54 g COD/g VSS.d and 0.21g COD/L, respectively. The regression line for the plotted linear equation of the Kincannon-Stover model had a R2 of 0.84 which was lower than that found for the Monod model with R2 of 0.985. Meanwhile, in the Monod model, the parameters of Y and Kd were obtained 0.073 g VSS/g COD and -0.008 d-1, respectively. The present study demonstrated that the Monod model is more suitable and applicable for formulating a kinetic model for prediction of the EFFLUENT SUBSTRATE CONCENTRATION and OPTIMUM VOLUME of the ABR at the similar operation conditions.
