1. A method of controlling the delivery of one or more agents in a biological wastewater treatment system, the method comprising:
applying power to a bio-electrochemical sensor;
measuring an electrical output of the bio-electrochemical sensor and correlating the output with metabolic activity of exo-electrogenic bacteria present in the wastewater treatment system;
correlating the electrical output with the one or more agents in the wastewater treatment system;
delivering the one or more agents into the wastewater treatment system;
monitoring a change in the electrical output in response to the delivery of the one or more agents; and
adjusting the delivery of the one or more agents in response to a change in the electrical output.
