Total Kjeldahl Nitrogen (TKN) is a measure used in wastewater treatment to quantify the total concentration of nitrogen in water, specifically encompassing both organic nitrogen and ammonia nitrogen. This method essentially captures all forms of nitrogen that can be converted to ammonia, which includes nitrogen from organic compounds as well as free ammonia present in the water.

By testing for both organic nitrogen and ammonia nitrogen, TKN provides a comprehensive overview of the nitrogen content in the sample allowing wastewater operators to assess the potential for nutrient pollution effectively. This multifaceted measurement is crucial for understanding nitrogen cycling and managing its impact on aquatic ecosystems.

While other options focus on isolated forms of nitrogen or specific categories, only the combination of organic and ammonia nitrogen reflects the full scope of TKN's analysis. This highlights the importance of including both components for an accurate nitrogen assessment in wastewater treatment processes.
