Biological pre-hydrolysis and thermal pretreatment applied for anaerobic digestion improvement: Kinetic study and statistical variable selection

In the present study, two pretreatment methods (thermal and biological pre-hydrolysis) were suggested for food waste (FW) with aim to enhance biomass conversion biogas production by anaerobic. The effects of thermal (TP), including TP at 60 °C 80 min, 100 °C, 120 140 30 well as pre-hydrolysis (BPH) 37 55 followed 40 h on anaerobic digestion performance FW evaluated in batch tests. Results compared untreated FW. BPH caused an increase soluble chemical oxygen demand hydrolysis efficiency. methane yield (MY) increased from 371.17 mL CH4/g VS 471.95 CH4/ g VS. maximal MY was recorded 20 h. pretreatments rate reduced lag phase. most influential variables investigated using three statistical methods: Principal component analysis, Mutual Information R-squared. results allowed a good modeling minimized overfitting effect.
