Production of Biogas from CO-Digestion of Cow Dung and Horse Dung ab 61.9 EURO
The demand for energy is geometrically increasing all over the world and there is need to harness energy from every opportunity and source nature bestowed.Biogas (biological gas) is obtained from the anaerobic fermentation or degradation of wastes, vegetable, cow dung, industrial, animal and poultry droppings and is a mixture of methane, carbondioxide and traces of hydrogen sulphide.It is a biological processes which involve three steps: hydrolysis,acid formation and methanization.Biogas formation is simply the conversion of simple compounds into methane. The amount of solid wastes generated in developing countries such as Nigeria has steadily increased over the last few decades as a result of increase in population and continuous growth of industries and agricultural activities. This book discussed the generation of biogas from various inputs to compliment the fuel usage in energy production.It is a must read to all energy students and tutors. It will enhance and contribute to the global drive for energy production.
Considering a present scenario there is a peak demand for energy in our country. Energy from the waste is one of the best methods to overcome this demand. Biogas can be obtained from the waste by "Anaerobic Digestion Process". The anaerobic digestion process is the biological oxidation of organic matter by the action of microorganisms in the absence of atmospheric oxygen. Organic matter is converted into stable end products at the same time, the process generates biogas (mainly methane and carbon dioxide). Conventionally cow dung is used for production of biogas. We have used food waste in addition to cow dung to generate biogas efficiently. As food waste is organic material having the high calorific value and nutritive value to microbes, it increases efficiency of methane production.
A number of nations have invested in research on biogas digesters, ranging from devices which can be used by a single household to industrial-scale equipment which could be used to generate large amounts of power.The Biogas Technology offers an efficient way of biomass utilization. It involves anaerobic fermentation of organic materials such as animal dung, agricultural wastes, aquatic weeds etc. to produce methane rich fuel gas and a value added organic fertilizer.The impact of industrial waste on the environment is a major concern and there is need for higher standards for waste minimization ranging from good operating practices to modification of the production process.The goal of the project is to promote adoption of technologies and best practice techniques for environmental benefits amongst industrial units.
Anaerobic digestion (AD) of biogas fermentation is very sensitively to temperature. So, temperature is main impact factor to biogas fermentation. Utilization of solar energy to increase the digester temperature, especially during cold climate, is very useful in heating biogas digesters because of its affordability. It is environmentally, friendly and economical. So, this study presents a new concept of using shallow solar pond (SSP) to increase the fermentation and biogas production rate during cold climate, therefore a new application of SSP by the integrating with a developed biogas digester was investigated at the Faculty of Agriculture, Zagazig University. The pre-constructed developed digester has been operated and evaluated compared to the conventional digester using dairy cattle dung. Due to the high productivity of the developed biogas digester, as well as a zero-waste engineering and environmentally sound system so this technology requires further more attention and study.
Projektarbeit aus dem Jahr 2015 im Fachbereich Energiewissenschaften, , Sprache: Deutsch, Abstract: A small scale floating drum biodigester was constructed with low cost, recyclable materials and the biogas generated was optimised with an aim to get the best possible combination of parameters to yield optimum biogas through the aid of a Mini-tab software version 17.0. The volume of biogas produced was 0.098 cubic meters, while the optimisation temperature was 28.4 degrees Celsius, being the highest temperature recorded and pH was 7.1. The initial capital invested took 17 years to breakeven.
