Microbial Interference: Some h2o samples may comprise a higher concentration of all-natural or released microorganisms that exhibit higher-than-average metabolic activity. This can result in elevated BOD test values and an overestimation of the organic and natural air pollution level.

These organisms can exert an oxygen demand because they change nitrogenous compounds (ammonia and organic and natural nitrogen) to far more stable types (nitrites and nitrates). At the least portion of this oxygen need is Generally calculated in a five day BOD.

mL required = (mL acid or base employed x mL overall test sample)/mL sample portion useful for neutralization.

A common challenge encountered in BOD testing effects from residues build up inside the BOD and dilution drinking water bottles. To prevent this, all glassware really should be acid cleaned frequently.

Time-consuming procedure: Acquiring BOD test effects calls for a comparatively very long timeframe, normally a number of times. This extended timeframe can hold off determination-producing procedures or fast actions according to the test results.
