Bod5 testing

WebNitrification as a cause of elevated BOD5 can be determined by analyzing the effluent sample using the regular BOD5 test and the inhibited or carbonaceous BOD5 test (cBOD). These two test results are generally within 10-20% of each other when nitrification is not significant (the cBOD value is usually a little less than the BOD5 value).
