Abstract

Biological Nutrient Removal of Nitrogen Using Cyclic Aeration: Application in a Full-Scale Activated Sludge Treatment PlantCyclic aeration is a biological nutrient removal (BNR) process that promotes denitrification by cycling aeration on and off in activated sludge basins. In this study, cyclic aeration was implemented in a full-scale activated sludge treatment plant with existing equipment, high average flows, and without mechanical mixers in the aeration basins. Cyclic aeration was evaluated with anoxic phases of...Author(s)Jennifer RuddySay K.
