Integration of kinetic modeling and desirability function approach for multi-objective optimization of UASB reactor treating poultry manure wastewater

► A holistic approach is proposed for multi-objective optimization of mesophilic UASB. ► Chen-Hashimoto and Stover-Kincannon models are integrated on a composite surface. ► A bio-economic model including several technical and thermophysical data is derived. ► Inhibition parameter is derived empirically for the first time for poultry manure. ► The methodology demonstrated a useful tool with an overall desirability of 0.896.
