Industrial labs tend to use more dilutions given that they receive quite a few samples and might not be as knowledgeable about the samples they get.
When BOD is lower, the dissolved oxygen existing while in the h2o human body is high. This means the drinking water is a lot less polluted by organic and natural issue.
It is critical which the distilled water employed for dilution water be of high quality and no cost from contaminants (for test for BOD example copper and chlorine) which could inhibit the growth of bacteria.
