Anaerobic digestion of cheese whey is a cost ‐ effective way to dispose the wastewater safely and at the same time benefit could be realized directly from the energy recovered in the form of biogas. Microwave irradiation as a method for sludge treatment has gained widespread popularity, mainly due to enhance biodegradability and increase yield of biogas. In this study the effect of the final temperature of the microwave treated whey on biogas yield was investigated. Treatment was performed in a continuous flow treating system at different irradiation power levels, whey concentrations and flow rates. Experiments indicated that both the yield of biogas and the final temperature of the concentrated whey were higher than the whey’s at the same set treating parameters. But the energy demands were higher in cases of concentrated whey because of the energy demand of membrane separation. Keywords : microwave pre ‐ treatment, biogas production (BP), anaerobic digestion.
