Kinetic Studies of Biogas Generation Using Chicken Manure as Feedstock

Maiduguri in North-Eastern Nigeria can boost of considerable amount of biogas generated from chicken manure (CM) if the organic waste is exploited for such purposes. The objective of this work is to determine the most accurate model for predicting biogas kinetic parameters by analyzing the CM empirical data obtained in Maiduguri. Biogas potential (BP) estimates using NLREG 6.6 software from the First Order and the Modified First-Order models gives BP = 10252217.1g and 83861.2925g respectively. The First Order model is the most correct kinetic model based on a careful assessment of statistical results gotten from both the ORIGIN and NLREG softwares. However, constant parameters estimated from the models, which would have helped significantly in optimizing future biogas production from CM are ambiguous and might be ascribed to errors in the biogas yield measurements or the inability of the selected models to effectively predict the constant parameters

“…This study, tends to explore the kinetic study of anaerobic co-digestion of banana peel, waste water treatment sludge and chicken dung using Monod model. The importance of kinetic models is to assess the growth of microorganisms in environmental conditions, forecast the behaviour of biochemical reactions, support engineers to design and control biological processes and, to define the performance parameters prompting the product yield (Ulukardesler and Atalay, 2018).…”

Solid waste when discarded to the environment causes serious environmental problems. The kinetic study of microbial growth in anaerobic digestion process is process specific, yet, there are limited reported studies with regards to the feedstock’s (banana peel, chicken dung and waste water treatment sludge). The objective of the study is to carry out the kinetic study of microbial growth, and to know the conditions or environment responsible for the degradation of chicken dung, waste water treatment sludge and banana peel for the production of biogas and biofertilizer. The methodology involves the use of serial dilution, pour plating, cell counting for microbial population and Monod parameters were determined. Microsoft excel 2016 was use to carry out regression analysis, results shows that the maximum, growth rate (????????????????) estimated from the basic Monod equation, of microorganism, was 0.098 hr-1 and the half saturation constant, (????????), 1.2 ×108 mg/l. This pin point the availability of substrate for the survival of microorganisms

Grass is a highly desirable substrate for anaerobic digestion because of its higher biodegradability and biogas/methane yield. It contains a large amount of organic matter, which can be digested anaerobically to produce biogas. Anaerobic co-digestion of grass, cow manure and sludge was studied under mesophilic conditions for 65 days. Experiments were performed on a feed ratio of grass/manure 5, 10, 15, 20, 25%, respectively. During the experiments the volume and concentration of biogas and methane were recorded daily. The maximum cumulative biogas and methane yield was obtained as 331.75 mLbiogas/gVS and 206.64 mLCH4/gVS for 25% ratio. Also, the results of the experiments were tested on the three different kinetics model which are the first order kinetic model, modified Gompertz model and Logistics model. As a result of the study, it was found that by using grass waste 1.2.109 kWh/year electricity may be produced and 1.106 tons/year CO2 greenhouse gas emission may be reduced.
