A generalized model for aerobic granule-based sequencing batch Reactor. 2. Parametric sensitivity and model verification.
The sensitivity of the effluent chemical oxygen demand, NH4+-N and volatile suspended solids concentrations toward the stoichiometric and kinetic coefficients, oxygen diffusivity, characteristics of granules, and operating parameters was analyzed. With such a parametric sensitivity analysis, calibration of the model, which was established for describing aerobic-granule-based sequencing batch reactor (SBR) in the accompanying paper, was performed by comparing the measured and predicted values for model components. Thereafter, the established model was verified with the experimental results for four aerobic-granule-based SBRs with different granule sizes and fed with different wastewaters. The verification results show that the model established in this work was applicable to simulating and predicting the performance of an aerobic-granule-based SBR.
