Abstract

Nitrification, the oxidation of ammonia to nitrate catalyzed by bacteria, is a key part of the global nitrogen cycle. In the first step of nitrification, chemolithoautotrophic ammonia oxidizers transform ammonia to nitrite, which subsequently oxidizes to nitrate by nitrite-oxidizing bacteria. This process can be affected by several factors. In this study, the effect of INFLUENT COD/N ratio on nitrification rate in a bench-scale biological reactor was investigated. Experiments were carried out using synthetic wastewater. The initial ammonium concentration was 25 mg NH+4 -N L-1. The effect of COD/N ratio between 10.01±0.083 and 24.08±0.22 gCODgN-1 on nitrification rate was investigated by varying the COD loading supplied to the reactor. From the results obtained, it may be concluded that in the range of 10.01±0.083 to 14.15±0.17 gCODgN-1, a direct relationship holds between COD/N ratio and nitrification rate. However, an indirect relationship holds between COD/N ratio and nitrification rate at ratios above 14.15±0.17 up to 24.08±0.22 gCODgN-1.
