Development of a comprehensive model and evaluation of kinetic coefficients for treating slaughterhouse wastewater in a single stage anaerobic bioreactor

A simplified method for determination of the kinetic coefficient for an anaerobic bioreactor has been developed in this present research. Kinetic coefficient, viz. specific substrate utilization rate (k), half-saturation constant (K-S), yield coefficient (Y) and endogenous decay rate (K-d) have been calculated using Monod kinetics for all three phases of anaerobic digestion. The single-stage anaerobic bioreactor was run under the semi-continuous mode of operation with varying Sludge Retention Time (SRT) and initial substrate concentrations (as soluble COD). The detailed experimental procedure of determination of kinetic coefficients from the experimental data set of semi-continuous studies for three different phases has been presented sequentially. The values of the kinetic coefficient are comparable with the earlier kinetics studies. The proposed method is found to be easy, accurate and fast for determination of the kinetic coefficient of individual phases of anaerobic treatment.
