Optimization and Quantification of Biogas Yield by Blending Cow Dung with Three Different Potential Substrates Under Anaerobic Condition Using Proto-Type Chinese Fixed Dome Bioreactor.
Abstract
Biogas technology is gaining global recognition as an eco-friendly technology with the potential to meet national needs such as electricity vehicular fuel, cooking gas and adding economical values. This study explores the optimization and quantification of biogas produce through blending cow dung with other potential waste under anaerobic condition. Co-digestions and varying of organic loading rate (OLR) were employed. The biogas process (Hydrophilic retention time) was monitored for 3 weeks; the temperature and the pH were measured using mercury-in-glass thermometer and digital pH meter. The proximate analysis was carried out using AOAC standard method. The gas produced was measured using weighing balance and the quality using portable gas analyser. The result of the proximate analysis revealed the nature of the co-digestion of each bioreactor. The bioreactor four (B4) had higher moisture contents of 94.20% and lowest in biogas produced (3kg), while bioreactor one (B1) had 92.6% as the lest, but with higher production of biogas (7kg). Low value of TFA (0.28%), nitrogen (0.14%) and carbohydrate (3.91%) could contribute to the poor production of biogas in B4. The quality and the flammability time of biogas produced in B3 and B4 were optimized compared to B2. The anaerobic degradation was carried out within the atmospheric temperature of 33.43?±-0.98?C and slurry temperature range of 31.14°C ±-2.852°C to 31.43?±-2.51°C.The pH of the process where also within the range7.51±-0.40 to 7.80±-0.29 which are within the normal biological pH for microorganisms. This implied that the nature of the waste had a direct effect on the production of biogas and co-digestion contribute to the optimization of the retention time and quality of methane gas produced.
