Design and building a digester to Produce Biogas in Rural Area

Abstract

This project concerns the building and design of home scale biogas generator from animal waste in rural area. Thus, the project is considered beside the design of the biogas generator, feasibility study for the production of biogas obtained from cattle dung. The importance of the project comes to shear in solving the problem of the global rising of the fuel cost. The aim is to design a generator to produce the methane gas through anaerobic treatment of cattle dung, taking into account all of safety issues. The digester done in the cylindrical shape and it provides appropriate condition such as heating and mixing system to allow the bacteria to produce the biogas in short duration. A sample of produced mixture has taken and tested a pH of the mixture was measured which is criterion of bacteria production with respect to the water temperature used of digester heating, The ph. measured value (6-7) are the best value and condition of biogas retention , the produced was tested and burned which utilized the purpose of this project.
