Abstract: A method of optimizing a wastewater treatment plant includes: providing an oxidation ditch having a dissolved oxygen set-point and including: an aeration system having an aerobic zone; and an anoxic zone; measuring the oxidation-reduction potential of the anoxic zone; and based on the measured oxidation-reduction potential: increasing or decreasing the dissolved oxygen set-point; increasing or decreasing a dose of supplemental nutrients; and/or increasing a dose of supplemental carbon or metal salts.
