BMP biogas VDI 4630: ISR, acclimation and kinetic fitting
BMP tests that do not comply with the VDI 4630 protocol introduce biases of 20-40% in the results. The critical points are the inoculum-to-substrate ratio (ISR ≥ 2 on VS), acclimation of the inoculum, the inclusion of triplicates and endogenous blanks, the termination criterion (daily production < 1% of the cumulative value) and kinetic fitting […]
