Advanced modelling and control of nitrous oxide emissions from wastewater treatment plants

This project aims to develop a unified N2O model capable of predicting the multiple N2O production pathways using statistically-analysed full-scale data from a database consolidated in this project. The unified N2O model will then be
incorporated to issue a new plant-wide model of high fidelity, which will be implemented to optimize plant design for minimum carbon footprint. By applying advanced control technologies in the plant-wide model, a variety of carbon footprint mitigation strategies will be generated and tested for WWTPs of different process configurations under varied operating conditions. The model-based control strategies will be implemented at full scale to evaluate their applicability to directing the operation of real WWTPs.
