| dc.description.abstract | In many waste treatments, the anaerobic digestion is considered as a friendly
method to environment and to generate the most yield methane. The goal of this
study is to investigate the impact of many factors to the anaerobic digestion of
municipal solid waste. Moreover, this study presents several runs of experiment
and analysis with the aim of shortening the duration of overall stage of digestion
process while optimizing the biogas generation with higher methane content. Two
temperature conditions (55oC and 37oC), three solid waste-inoculum (S:I) ratios
were 1:2, 2:1, 1:1 and five percentages of total solid were 30%, 24%, 18%,
14%, 10% tested for each reactor, respectively. The result indicates that in the
thermophilic, 24% with S:I ratio of 1:2, the reactors generate the highest
methane yield of 126.97 (mmole/ml) during 30 days. This result could be helpful
for municipal solid waste treating in VietNam.
