Claim 17:
18. A method for treating wastewater and generating electricity, the method comprising:
receiving, by a single-chamber reactor via a wastewater inlet tube connected to a bottom opening of the single-chamber reactor, wastewater to be treated;
passing the wastewater through a first layer of gravel disposed on a bottom surface of the single-chamber reactor;
passing the wastewater through a first layer of sediment above the first layer of gravel, the first layer of sediment containing microorganisms for treating the wastewater;
passing the wastewater through a first layer of granular activated carbon or granular activated carbon with graphene oxide or sand with graphene oxide disposed on top of the first layer of sediment for enhancing electron transfer, current generation rate, and wastewater treatment;
passing the wastewater through one or more anodes located on top of the first layer of granular activated carbon or granular activated carbon with graphene oxide or sand with graphene oxide;
passing the wastewater through a second layer of gravel disposed on top of the one or more anodes;
passing the wastewater through a second layer of sediment disposed on top of the second layer of gravel and containing microorganisms for treating the wastewater;
passing the wastewater through a second layer of granular activated carbon or granular activated carbon with graphene oxide or sand with graphene oxide disposed on top of the second layer of sediment for enhancing electron transfer, current generation rate, and wastewater treatment;
passing the wastewater through one or more cathodes located on top of the second layer of granular activated carbon or granular activated carbon with graphene oxide or sand with graphene oxide;
generating, by the one or more anodes and the one or more cathodes, electrical voltage; and
emitting, by the single-chamber reactor via a treated water outlet tube connected to a top opening of the single-chamber reactor, treated water.
