Electricity Generation from Biogas Produced in a Lab-Scale Anaerobic Digester Using Stirlingmotor
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 6, Issue 3
Abstract
The sludge produced during wastewater treatment should be stabilized in order to minimize the damage to the environment. This study includes the evaluation of sludge stabilization and biogas formation by anaerobic digestion in order to generate electricity using stirling motor. The study was carried out with the raw sludge form the thickener of the waste watertreatment plant. The main aim of the study is to provide sludge stabilization resulting biogas production by reduction of organic matter and to generate electricity. Anaerobic digestion studies were carried out using a laboratory scale anaerobic reactor with a volume of 7L.Under themesophilic condition, the sludge age was maintained at 10 days during the first 20 days of operation, while the reactor was operated for 90 days until the end of the run, with a sludge age of 20 days.The results have changed in the range of 42-52% after the organic matter reduction obtained from the anaerobic digestion. Concentrations of 3735.7300 ppm, 5060.5768 ppm, and 6951.4013 ppm biogas were obtained. Biogas was turned on by mechanical energy with a Stirlingmotor and then turned to direct current and the lamps with 3V 20mA each were run for 60 minutes.
