WebA standard BOD test is run using seeded dilution water. In one bottle, the waste sample is mixed with seeded dilution water giving a dilution of 1:30. Another bottle, the blank, contains just seeded dilution water. Both bottles begin the test with DO at the saturation value of 9.2 mg/L. WebThe dilution factor is only calculated when there is volume of liquid added to the sample. For instance, say you start with 10mL of cell suspension. You add 5mL of water, so your final volume is 15mL. Then the dilution …
