Nitrification cycle in wastewater
WebbIn this colorimetric method, use for drinking water, wastewater and seawater, nitrate is reduced to nitrite with hydrazine sulfate. The diazonium reagents then react with the nitrite to produce a red color. The intensity of the color is proportional to the original amount of nitrate and nitrite present in the sample. Webb• Biological nitrification reduces dissolved oxygen concentrations in receiving waters and may impact aquatic life • Magnitude of DO depletion is impacted by receiving water …

WebbThere are two steps for removing nitrogen in biological treatment: nitrification and denitrification. In this process, nitrifiers, including ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB), convert total ammonia (free ammonia and un-ionized ammonia) to nitrate.
