ABSTRACT:
A method for treating municipal wastewater in an oxidation ditch activated sludge system by automated determination of the nitrogen depletion inflection point, which enables anoxic cycles to be utilized to achieve improved settling of the activated sludge by providing selective pressure against the growth of filamentous bacteria, by providing improved total nitrogen removal, by providing energy savings and by providing recovery of alkalinity.
