Denitrific ation of a high ammonia leachate using an external carbon source

Abstract
A single‐sludge, nitrification‐denitrification system was used to treat a high ammonia (170–230 mgL−1), low biodegradable carbon (B0D5 = 10–40 mgL−1) landfill leachate. Glucose and methanol were used as external carbon sources for denitrifi‐cation. Complete ammonia removal was consistently achieved; when glucose was used as the carbon source, inconsistent denitrification performance was experienced (fluctuated between 10–100%). However, with methanol, the denitrification performance was consistent and reliable, with complete denitrification achieved.
