dc.description.abstract | Optimization was done by investigating the interaction effects of total solids, mesophilic
temperature, and substrate retention time on biogas production in a batch biodigester. The volume of
the biodigester was 0.15m3
. Central composite design of Response Surface Methodology was used to
design the experiment. Total solid levels were varied from 6.31% to 9.68%, temperature was from
26.59°C to 43.41°C, and substrate retention time was from 9.95 to 20.04 days. Analysis of results was
done using Design Expert software statistical package (version 10.0.0.3). It gave a coefficient of
determination of 0.9665 which indicated a high correlation between the variables. All the variables
had a significant effect. The highest biogas production rate of 75.41litres/day (or 0.50 m3
of biogas
per m3
of digester volume per day, m3
/m3
d) was achieved at a level of 8% total solids, a temperature
of 43.41°C, and a substrate retention time of 15 days. | en_US |
