This research will begin with the statement that sewage plants consume a lot of power although they also generate a lot of heat and power. They generate heat through biogas production, which is purified and used to power locomotive machines like gas motors. The process of biogas production requires power especially in the fermentation and decomposition process because of temperature regulation. This is to say that production of energy from sewerage plants includes both aspects of increasing energy efficiency and reducing energy consumption. Biogas is produced through a process of anaerobic digestion. Biogas production is environmentally friendly. Biogas is a gas produced through the breakdown of organic matter in the absence of oxygen Sewage plants produce biogas, which is a good source of energy. During the sewage treatment process in the sewage plant, a lot of energy is consumed approximately 50 kWh per person. That means that a substantial amount of energy is required to treat sewage from the population. Research shows that sewage treatment is one of the sectors, which requires a lot of electricity. Biogas is a renewable source of wind and solar energy. For the production of biogas to occur, the sewage undergoes a process known as anaerobic digestion. In this process, anaerobic bacteria are used to break down the waste materials. The biogas produced is mainly carbon dioxide, methane, and small amounts hydrogen sulfide. Gases produced hydrogen. methane and carbon monoxide oxygen oxidize them to allow a release of biogas used as fuel.
