Pilot Testing of Bioaugmentation Using Post-Aerobic Digester Biomass as a Source of Nitrifiers

Anaerobic-aerobic phased digestion, or post-aerobic digestion, is a promising advanced digestion process applying the sequential operation of anaerobic digestion followed by aerobic digestion. Post-aerobic digestion provides total nitrogen removal without the need for chemical addition in addition to enhanced volatile solids reduction. Since nitrification occurs in the post aerobic digester,...
