In the present effort to manage water resources more sustainably, wastewater is now viewed as a resource that may be used for electricity, plant nutrients, and water. The primary focus is the exploitation of organic materials and microorganisms from wastewater to produce electricity. The organic stuff is used by the organisms in the wastewater for metabolic processes. The prospect of direct biological conversion of wastewater's organic components into energy exists, even if major breakthroughs are needed for this process to compete with anaerobic biological conversion of wastewater organics into electricity generation. With the development of more advanced membrane techniques and full anaerobic wastewater treatment, wastewater treatment could cease to be a significant energy consumer and instead become a net energy producer. The treatment of home wastewater and the use of graphite electrodes by microorganisms to generate energy are the main topics of this research. Because graphite has a large surface area and is noncorrosive, it is an excellent material for use in waste water applications.
