When BOD is low, the dissolved oxygen current in the drinking water overall body is higher. This indicates that the h2o is much less polluted by natural make a website difference.
It ought to be pointed out the seed correction for every sample dilution should be calculated if the seed is included on the dilution h2o. If the seed is included on to Each individual BOD bottle, the seed correction is the same for all seeded dilutions utilizing the same seed volume and product.
