  • Plant-sediment microbial fuel cell system for wastewater treatment with self-contained power sustainability
    Patent number: 11888200
    Abstract: Methods, systems, and apparatus for treating wastewater and generating electricity. The system includes layers of sediment containing microorganisms for treating the wastewater. The system includes layers of granular activated carbon or granular activated carbon with graphene oxide or sand with graphene oxide disposed on top of the sediment layers for enhancing electron transfer, current generation rate, and wastewater treatment. The system also includes one or more anodes and one or more cathodes located on top of the layers of granular activated carbon or granular activated carbon with graphene oxide or sand with graphene oxide. The one or more anodes and the one or more cathodes are configured to generate electrical voltage. The system also includes a battery connected to the one or more anodes and the one or more cathodes and configured to store the electrical voltage generated by the one or more anodes and the one or more cathodes.
