Abstract

The inf luence of t race elements (Co2+ , Ni 2+ and Fe 3+~ in v a r y - ing concentrations and combination, was studied in 1.5 m Khadi & Village Industries Commission (KVIC) digesters for biogas generation from mangopeel. Addition of these trace metals enhanced the biogas yield and methane content moderately, the maximum being with the iron fed digester. The digesters were always found to be stable without much variation in total volatile fatty acids (VFA), pH, total alkal i n i t y and other parameters. A methane content of 62~0 and biogas yield of 0.49 m 3 /kg VS added was obtained with 4000 mg/L FeCI 3 supplemented mangopeel fed digester as compared to control having biogas yield of 0.22 m3/kg VS added with a methane content of about 48-50%.
