Stopper the bottle with treatment to be sure no air is launched. Mix the sample by inverting quite a few periods. Check for air bubbles; discard the sample and start over if any are seen.
Significant BOD amounts are due to higher consumption of dissolved oxygen by microorganisms. It indicates the drinking water is extremely polluted with organic and natural issue.
If your DO is lower, shake or aerate with filtered compressed air to enhance the DO concentration. Keep in mind, commencing with a higher initial DO will enable you to go over a broad BOD assortment with Each individual dilution.
