Biostabilization Assessment of MSWI Bottom Ash Addition on MSW Digestion in Anaerobic Bioreactors
(0) Municipal solid waste (MSW) incinerator (MSWI) bottom ash has been utilized as aggregate, road base, backfill and soil amendment. Using bottom ash as soil cover is rare and the base line information is not fully understood. Thus, this study aims to investigate the possibility of MSWI bottom ash as landfill cover and find out the proper MSWI/MSW ratios suitable for landfill or anaerobic digestion. MSWI/MSW ratios of 0 (control), 100, 200, 400 and 600 g/l were used to conduct the experiment in anaerobic bioreactors. Results showed that gas production in all 100, 200, 400 and 600 g/l ash added bioreactors were found higher than that of control one. Rank order of gas production was found to be 100 g/l>200 g/l>400 g/l>600 g/l>0 g/l. Parameters such as pH, electrical conductivity, chemical oxygen demand, alkalinity, volatile acids, total solid, volatile solid and metals were measured and compared to explain the difference of gas production. Gas production difference was further investigated by ANOVA and regression analysis.
