NOVELTY - Sustainable wastewater and biosolids treatment using a bioreactor including microbial fuel cell (102) involves enriching anode of microbial fuel cell in bioreactor with substantially soluble electron acceptor; growing bacteria in presence of anode (114) enriched with soluble electron acceptor; oxidizing substrate using bacteria to produce free electrons; channeling free electrons away from terminal electron acceptor and to enriched anode, enriched anode serving as electron acceptor; and carrying free electrons from enriched anode to cathode of microbial fuel cell to generate electricity.    USE - For treating sustainable wastewater and biosolids e.g. domestic wastewater (claimed); and for production of electricity.    ADVANTAGE - The method provides treatment of wastewater and biosolids in sustainable manner. The wastewater and biosolids treatment using microbial fuel cell, which has improved electricity generating capabilities; by extracting energy from system treating wastewater and biosolids, the cost of method is reduced; the wastewater treatment, as energy production uses the organic wastes as a substrate in energy production.    DETAILED DESCRIPTION - Sustainable wastewater and biosolids treatment using a bioreactor including a microbial fuel cell (102) involves enriching anode of microbial fuel cell in bioreactor with substantially soluble electron acceptor; growing bacteria in presence of anode (114) enriched with the soluble electron acceptor; oxidizing substrate using bacteria to produce free electrons; channeling free electrons away from terminal electron acceptor and to enriched anode, enriched anode serving as electron acceptor; and carrying free electrons from enriched anode to cathode of microbial fuel cell to generate electricity. Substantially soluble electron acceptor is iron (iii) chloride. An INDEPENDENT CLAIM is included for a system for producing a microbial fuel cell having improved electricity generating capabilities comprising a bioreactor module including a bioreactor; and substantially soluble electron acceptor; a transfer module including for serially transferring bacteria grown in the presence of anode enriched with a substantially soluble electron acceptor from bioreactor to a second bioreactor having a microbial fuel cell by seeding second bioreactor; a treatment module including second bioreactor for oxidizing elements of domestic wastewater and/or biosolids using primarily serially transferred bacteria, and for generating electricity.
