Next generation nutrient approaches like partial nitrification, denitrification, anammox, leveraging internal carbon storage for denitrification, simultaneous nitrification and denitrification and sidestream enhanced biological phosphorus removal (EBPR) can allow utilities to reduce cost, footprint, energy and chemical demand associated with nutrient removal.
Hazen is helping to lead the adoption of NGN processes at water resource recovery facilities. We understand the intricacies associated with implementing NGN. We know that NGN is not a silver bullet and requires increased reliance on instrumentation and real time process controls. Our phased approach to NGN allows a utility to implement NGN on a schedule that provides best value and avoids unnecessary complexity and costs.
Key advantages of next generation nutrient removal (NGN) include increased process capacity, reduced operations and maintenance (O&M) and greenhouse gas, simplification of operation, and positioning the utility to perform resource recovery and process intensification.
