Nitrification and Denitrification in Wastewater Activated Sludge
By Heather Jennings, PE The great teeter-totter of wastewater is the nitrification and denitrification cycle in activated sludge wastewater systems. It takes both to convert ammonia to nitrogen gas! Both processes feed off of and support each other but, in some ways, they have competing needs. Nitrification consists of ripping off the hydrogen in ammonia and adding oxygen
