Understanding and mitigating nitrous oxide emission from wastewater treatment plants (2009-2012)
Abstract
A critical challenge for the wastewater industry to achieve its goal of greenhouse gas neutral operation is the mitigation of nitrous oxide emission during biological nitrogen removal. Through integrated laboratory studies, mathematical modelling and extensive full-scale monitoring and optimization, this project will deliver (1) detailed process data for accurate determination of N2O emissions from major types of wasterwater treatment plants; (2) operational strategies, including on-line control systems, that minimize N2O emission from these plants; and (3) a mathematical model capable of predicting N2O emission, to provide strong support to the industry in its endeavour to achieve carbon neutral wastewater management.
