Examples of Kjeldahl Nitrogen in a sentence

  • For the purposes of the Permit, the term “Total Nitrogen (TN)” is defined as the calculated sum of analytical results from “Total Kjeldahl Nitrogen (TKN)” plus “Nitrate-Nitrite”.

  • It also contains monitoring requirements for total nitrogen, Total Kjeldahl Nitrogen, and nitrate/nitrite.

  • TN is a calculated value based on the sum of Total Kjeldahl Nitrogen (TKN) and Nitrate/Nitrite (NOx) Nitrogen, 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.

  • TN is a calculated value based on Total Kjeldahl Nitrogen (TKN) and Nitrate/Nitrite (NOx) Nitrogen.

  • To gather data on the amount of Total Nitrogen (TN) in this discharge and its potential impact on the receiving water, a monthly “monitor only” requirement for Nitrate/Nitrite (NOx) and Total Kjeldahl Nitrogen (TKN) has been included in this permit.

  • Monitoring for Nitrates + Nitrites, Total Kjeldahl Nitrogen, Total Nitrogen, and Total Phosphorus are included in this permit.

  • Monitoring for Total Kjeldahl Nitrogen (TKN), Nitrite + Nitrate Nitrogen, and Total Nitrogen shall be conducted once each year in rotating quarters in order to collect seasonal information about the discharge.

  • This permit requires that the Total Kjeldahl Nitrogen calendar year application amount shall not exceed 165 pounds per acre per year, except when alternate numerical nitrogen loading limits (consistent with the above sections of NR 214) are approved in writing via the Department’s land application management plan approval.

  • If the amounts do not match the originally reported values the submission will be rejected.

  • UOD is dependent on the quantity of Biochemical Oxygen Demand (BOD5) and Total Kjeldahl Nitrogen (TKN) in a discharge, as specified in the following equation: UOD (lbs/day) = [(BOD5 (lbs/day) x 1.43) + (TKN (lbs/day) x 4.57)] Calculation of the UOD concentration in the discharge is unchanged from the current permit and required weekly per month from the period of June 1 through October 31.
