The purpose of this grant is to promote scientific progress towards preventing and controlling harmful algal blooms (HABs). This project is focused on one aspect of the grant opportunity: to evaluate the scale-up of emerging nutrient treatment technologies and develop new technologies.
This project is funded through the U.S. Environmental Protection Agency (EPA) Science to Achieve Results (STAR) grant opportunity “Approaches to Reduce Nutrient Loadings for Harmful Algal Bloom Management” (EPA Grant Number: 84008601-0).
The specific objective of this project is to pave the way for full-scale applications of shortcut N removal processes, by increasing nitrite availability for anaerobic ammonium oxidizing bacteria (anammox) in mainstream systems. Shortcut N removal systems developed based on the partial denitrification (PdN) route rather than the NOB (nitrite oxidizing bacteria) out-selection route, will likely provide more reliable nitrite production and could accelerate the full-scale implementation of shortcut N technologies.
- The total project funding is approximately $1 Million.
