Abstract
To obtain enriched methane content and improve the anaerobic digestion of a mixture of cattle dung, poultry waste and cheese whey, with enri ched methane content, the effect of various surfactants was studied. A mong the surfactants tested, Tween 80 and sodium lauryl sulphate showe d the maximum enhancement in gas production as well as methane content , indicating better process performance. The Tween 80 dosed digester ( 300 muL/L) produced about 3.5 L gas/L of digester/d with 70% methane. Results also indicated increased percent COD reduction in the presence of Tween 80.
