The dilution water blanks are utilised only to check the standard of the test for BOD dilution h2o. If the quality of the drinking water is nice and free from impurities, the depletion of DO need to be fewer than 0.two mg/L. In almost any celebration, usually do not utilize the depletion attained as a blank correction.
