The road to net zero & the N2O challenge
 N2O has a global warming potential (GWP) 265-298 times higher than CO2
 N2O production is complex: Denitrification or Nitrification process
 Location: activated sludge units/ sludge storage tanks

Existing preventive measures –
prevent/ mitigate N2O formation
Optimising DO control in aeration
Reduce DO and NO2 – level in anoxic zone
Maintain optimal C/N ratio in anoxic zone
