Kinetic prediction of biochemical methane potential of pig slurry

Empirical Kinetic Models have been used to describe and establish the Anaerobic Digestion kinetics of pig slurry’s (8% TS) Biochemical Chemical Potential. A wide selection were fitted experimental data collected in batch assays different Substrate Inoculum ratios, 0.65 (BMP1) 1 (BMP2). For most suitable model for each BMP assay, statistical tools R2 RMSE, along with Information Criterion AIC BIC, taken into consideration. From all studied models, Weibull proved be kinetic parameter prediction both BMP1 BMP2 assays. This presented lowest values highest value RMSE. In this regard, a R2=0.998, RMSE=0.004, was obtained BMP1, R2=0.999 RMSE=0.008 BMP2.
