Abstract :
This study aims at investigating the effects of MSW incinerator fly ash (FA) and bottom ash (BA) on the anaerobic co-digestion of OFMSW with FA or BA. It also simulates the biogas production from various dosed and control bioreactors. Results showed that suitable ashes addition (FA/MSW 10 and 20 g L−1 and BA/MSW 100 g L−1) could improve the MSW anaerobic digestion and enhance the biogas production rates. FA/MSW 20 g L−1 bioreactor had the higher biogas production and rate implying the potential option for MSW anaerobic co-digestion. Modeling studies showed that exponential plot simulated better for FA/MSW 10 g L−1 and control bioreactors while Gaussian plot was applicable for FA/MSW 20 g L−1 one. Linear and exponential plot of descending limb both simulated better for BA/MSW 100 g L−1 bioreactor. Modified Gompertz plot showed higher correlation of biogas accumulation than exponential rise to maximum plot for all bioreactors.
