Total Kjeldahl Nitrogen (TKN) measures all organic nitrogen and ammonia at the influent. It is important to remember that much of the organic nitrogen will be converted to ammonia during biological treatment. Alkalinity and oxygen requirements need to reflect the organic nitrogen and ammonia nitrogen concentrations.
