摘要：Biogas produced by biomethanation of dairy wastewater, contributes to sustainable reliable and renewable energy. Due to the lack of proper treatment facilities; the waste undergo degradation naturally resulting in methane and other green house emissions into the atmosphere. An attempt was made to convert the waste into sustainable, reliable and renewable energy. In the present study biomethanation of dairy wastewater were studied in a 13L biodigester with a HRT of (1.87, 2.08, 2.88, 3.74,5.34) days. The production of biogas was for 0.18 to 0.37 m3 of gas/kg COD removed.
