BOD Determination made easy
BOD (Biochemical Oxygen Demand) Determination is a simple and easy way for
monitoring the microorganisms’ activity in water samples with extremely reliable
results.

In particular, microorganisms present or inoculated in a water sample containing
biodegradable organic substance, consume oxygen for their metabolic activity
and produce a corresponding volume of carbon dioxide.

The carbon dioxide get absorbed by a strong alkali positioned in the neck of the
bottle. The result of this process is a decrease in gas pressure. The BOD measure
this change in gas pressure between the beginning to the end of the analysis and
give a result expressed in mg/l .
