Effects Of Temperature And Substrate Properties On Biogas Production Yield From Fresh Cattle Cud

ABSTRACT

 In this work, the effect of temperature and substrate properties on biogas yield from cattle for the production of biogas were anaerobically studied. Laboratory sized, air tight, mini digester was used for the retention period of 3 Odays with each system maintained at specific temperature with deionized water in the ratio of 1: 1 .the sample was thereafter analyzed for crucial physical properties (moisture, pH, conductivity, carbon, nitrogen, ash and carbon to nitrogen ratio) before and after anaerobic digestion. At the end of digestion, values for nitrogen, conductivity and moisture content increased significantly, while the value for carbon, pH, ash and volatile matter significantly reduced. consequently, the final cumulative biogas yield at the corresonding temperature were 39.00,105.10,24.80,910.80 and 111.50cm3respectively. overall, the 45 C gave the most and best maximum yield.
