WebBOD is calculated from the DO depletion and volume of sample used following the formula below: BOD 5 = BOD mg/L = [ (IDO -DO 5) – seed correction] x dilution factor Relying …
WebThe BOD test is an estimate of the food available in the sample. The more food present in the waste, the more Dissolved Oxygen (DO) will be required. The BOD test measures the strength of the wastewater by measuring the amount of oxygen used by the bacteria as they stabilize the organic matter under controlled conditions of time and temperature. WebBOD = biochemical oxygen demand, mg/L The correction factor for a bottle of Seed is derived using Equation 3. where: C = correction factor for oxygen depletion resulting from presence of seed ISDO = initial D.O. for …
WebCalculations: In general, BOD5 values less than 2.0 mg DO/L should be reported on DMRs as non-detects ( i.e., < LOD). Using the data recorded for un-seeded samples: BOD mg/l = (Initial DO - DO5) x Dilution Factor … WebBOD 5 /CBOD 5 Seed Correction Factor (NC WW/GW LC Policy 04/24/2013) The DO uptake attributable to the seed generally should be between 0.6 and 1.0 mg/L but the …
