Enhanced Step-Feed Biological Nitrogen Removal via Simultaneous Nitrification and Denitrification at NYC WPCPs
Previous studies conducted by the New York City Department of Environmental Protection (NYC DEP) have clearly identified step-feed biological nitrogen removal (BNR) as the backbone of their proposed nitrogen removal program. The key focus of NYC DEP's program is to accomplish phased reductions in effluent nitrogen loads in a timely and cost-effective manner. Towards this goal, NYC DEP is currently optimizing several factors such as supplemental carbon dose and location, froth control, influent flow split and reactor configuration, among others. This study focuses on the application of simultaneous nitrification and denitrification (SND) and therefore reduce costs associated with energy (aeration) and supplemental nutrients (organic carbon sources), which are essential to sustain the BNR process. The objectives of this study are :
