Ammonia concentrations encountered in water vary from less than 10 μg ammonia nitrogen/L in some natural surface and groundwaters to more than 30 mg/L in some wastewaters. In this manual, organic nitrogen is referred to and reported as organic N, nitrate nitrogen as NO 3 − -N, nitrite nitrogen as NO 2 − -N, and ammonia nitrogen as NH 3 -N.

Many concentrated ,wastewater, streams produced in food and agro- industry are treated using sludge digestion, and effluents from this process frequently contain ,ammonia, in high concentrations (up to 2 kg/m3). Typically, 40-50-% of the ,total nitrogen, in a municipal treatment plant is found as ,ammonia, in the centrate or filtrate streams.

Lesson 8: Nitrification and Denitrification

Biological nitrification is the microbe-mediated process of oxidizing ammonia to remove nitrogenous compounds from wastewaters. Domestic sewage typically contains 20 to 40 mg/L of ammonia nitrogen (NH 4- N). Organic matter containing nitrogen, e.g., protein and nucleic acid, also biodegrades to …
