The present disclosure relates to a sensor for monitoring metabolic activity of a population of exo-electrogenic bacteria in response to one or more agents in oxygenated water or wastewater in a water or wastewater treatment system. The sensor comprises: at least one electrode pair comprising an anode and a cathode, the anode in electrical communication with the exo-electrogenic bacteria for receiving electrons therefrom; a current sensor for measuring electron flow between the anode and the cathode and producing an electrical output that correlates with metabolic activity of the exo-electrogenic bacteria; and a power source in electrical communication with the electrode pair for delivering a voltage across the electrode pair. A method, system, and exo-electrogenic bacteria used for monitoring and/or controlling one or more agents in oxygenated water or wastewater is also provided.

Bio-electrochemical sensor, system, and method for optimizing performance of a water or wastewater treatment system

The present disclosure generally relates to a system for monitoring and/or controlling one or more agents, such as cleaning agents, in a wastewater treatment system. The system comprises a bio-electrochemical sensor for monitoring metabolic activity of a population of exo-electrogenic bacteria and providing an electrical output corresponding with the metabolic activity, where the bio-electrochemical sensor comprises an electrode pair and a power source for delivering a voltage across the electrode pair, and an electrical output analyzer for analyzing the electrical output and correlating the electrical output with the one or more agents in the wastewater treatment system. a change in electrical output beyond a threshold indicates that an adjustment in the delivery of the one or more agents is needed. a method and sensor for monitoring and/or controlling a cleaning process in a wastewater treatment system are also provided. The system, method, and sensor disclosed herein are particularly useful for cleaning membranes incorporated in a wastewater treatment process.

Bio-electrochemical sensor and method for optimizing performance of a wastewater treatment system

The present disclosure generally relates to a system for monitoring and/or controlling the delivery of one or more organic carbon compounds to a wastewater treatment system. The system comprises a bio-electrochemical sensor to monitor metabolic activity of a population of exo-electrogenic bacteria and provide an electrical output corresponding with the metabolic activity, the bio-electrochemical sensor comprising an electrode pair and a power source to deliver a voltage across the electrode pair, and an electrical output analyzer to analyze the electrical output and correlate the electrical output with a value representing the amount of the one or more organic carbon compounds in the wastewater treatment system. A method and sensor for monitoring and/or controlling the delivery of one or more organic carbon compounds to a wastewater treatment system are also provided.
