Abstract:
Seven anaerobic batch reactors were run
varying the Desiccated Coconut wastewater (DC) to
Food Waste (FW) ratio at room temperature and the daily
gas production and CH4 content was determined. Mono
digestion of DC wastewater with a lipid concentration of
1600 mg/L showed significant lipid inhibition. All the
co-digestion experiments resulted in enhanced biogas
production. The highest methane percentage of 78.19%
was obtained in the reactor with the DC:FW ratio of 3:2.
The results suggest that the application of co-digestion
effectively overcome the lipid inhibition in the anaerobic
digestion of desiccated coconut wastewater with an
enhanced methane production.
