1. An apparatus for treating wastewater comprising:
a first zone adapted to receive a mixed stream comprising previous, anaerobically treated wastewater from a second zone, wherein the previous, anaerobically treated wastewater facilitates direct transport and passage of one or more second biological microbes from the second zone to the first zone, said first zone comprising a first bioreaction zone, wherein the first bioreaction zone is configured with one or more retaining or facilitating structures that retain or facilitate growth of one or more first biological microbes and convert organic matter in a first liquid stream or a combination of the first stream and the mixed stream into at least carbon dioxide to produce treated wastewater;
a second zone adapted to receive the treated wastewater from the first zone, said second zone comprising a second bioreaction zone comprising a plurality of anaerobically facilitating structures configured to anaerobically facilitate growth of one or more second biological microbes; and
wherein said plurality of anaerobically facilitating structures comprise a pair of electrodes comprising both an anode and a cathode configured to further treat the wastewater and at least convert the carbon dioxide into methane.
