For measurement of carbonaceous BOD (cBOD), a nitrification inhibitor is extra following the dilution drinking water is added towards the sample. The inhibitor hinders the oxidation of ammonia nitrogen, which supplies the nitrogenous BOD (nBOD). When doing the BOD5 test, it can be regular follow to measure only cBOD since nitrogenous demand from customers isn't going to replicate the oxygen demand from customers from organic make any difference.
