TKN definition

TKN means Teekay Norway AS of Verven 4, N-4014, X.X. Xxx 0000, X-0000, Xxxxxxxxx, Xxxxxx.
TKN means the total Kjeldahl nitrogen content of a sample, including all of the ammonia and organic nitrogen compounds which are converted to ammonium sulfate under the conditions of digestion described in Standard Methods.

Examples of TKN in a sentence

  • The following EPA methods are recommended for use in the analysis of TKN and Nitrate + Nitrite.

  • Provide the average and maximum concentrations of ammonia (as N), total Kjeldahl nitrogen (TKN), organic nitrogen, nitrates (as N), total phosphorus (as P), and total solids (percent solids) of the sewage sludge that was land applied during the reporting year.

  • TN is a calculated value based on the sum of NOx and TKN, and, shall be reported as pounds, calculated as: Average TN (mg/L) x Total Daily Flow x 8.34 where, TN (mg/L) = TKN (mg/L) + NOx (mg/L)Per EPA excess nitrogen (N) and phosphorus (P) are the leading cause of water quality degradation in the United States.

  • The BOD and TKN analyses used to calculate UOD must be conducted on the same effluent sample.

  • Effluent flow, pH, oil and grease, BOD5, TSS, Total Nitrogen (including TKN and Nitrate-Nitrite), Total Phosphorus, and any applicable supplemental parameters are to be monitored during any discharge.
