DESIGN OF AN ANAEROBIC SYSTEM TO CONVERT MUNICIPAL AND INDUSTRIAL WASTEWATER INTO FUEL

Abstract

Due to a lack of resources and technical capabilities, the World has been experiencing energy problems over the past few years. Furthermore, nonrenewable energy resources are rapidly depleting. As a result, the world has an urgent necessity for an alternate, renewable energy source capable of addressing its energy challenges at this moment. It is difficult for the authorities to provide sufficient energy to the local community due to low reserves of natural gas worldwide and unstable economic status. Biogas technology can be used as an alternative to provide natural gas / energy to people, particularly those living in rural locations where natural gas is in short supply. Our final year project mainly focuses at production of Biogas at maximum achievable efficiency with the addition of Manure. Our major source of feed stock is Municipal and Industrial Waste which comprises mainly of organic content. We will run a continuous process at optimum mesophilic conditions after the completion of mass & energy balances to conserve the laws. During the process certain parameters, such as temperature and pH will be controlled according to literature review to achieve maximum efficiency. Biogas produced is later treated using an absorption column for the removal of CO2 and H2S traces to achieve pure methane which can be used as electricity, direct fuel for vehicles or for heating purpose.
