Resumé

Nitrous oxide emissions from sidestream deammonification reactors can pose a threat to utilities aiming to achieve carbon neutrality. The Ejby Mølle WWTP, in Denmark, has been monitoring nitrous oxide emissions since the sidestream reactors started operations in 2014 and big efforts have been made in order to better understand the driving forces behind nitrous oxide emissions under different dynamic operational conditions. Results from the first stage of the study are now being translated into developing new control strategies. A continuous aeration control is being the first control tested at the moment with very promising results. Changing from an intermittent aeration to continuous aeration has resulted in a drastic drop in nitrous oxide emissions compared to the control reactor.
