If not, little quantities of digester supernatant, return activated sludge, or an acclimated seed content may be used to enhance the potency with the seed content used for the test. As a substitute, commercially readily available seed substance might be utilised. The seed correction should not exceed one.0 mg/L BOD, for that reason care needs to be taken not to work with way too sturdy a seed materials for the test. The true secret to an excellent seed correction is a relatively stable seed content which provides a great seed correction in every test scenario.

SEED CORRECTION:- The calculation with the seed correction is based on the BOD of your seed content and the quantity of seed Utilized in each dilution. The seed correction is in fact the oxygen demand exerted by the oxidation of the compact volume of organic subject from the seed content while in the sample dilutions.
Temperature Fluctuations: BOD tests call for precise temperature Command during incubation. Fluctuations during the incubation temperature can influence the metabolic activity of microorganisms, leading to inaccurate BOD measurements.
