Effect of artificial aeration on tertiary nitrification in a full-scale subsurface horizontal flow constructed wetland

► Artificial aeration improved ammonium removal from 11% to 99%. ► Up to 10gNH4+-N/m2/d treated, without impairment of solids and organics removal. ► Aerated wetlands had improved hydraulic mixing patterns. ► Aerated wetlands are the lowest whole life cost nitrifying technology option. A full scale...
