Otherwise, modest portions of digester supernatant, return activated sludge, or an acclimated seed content can be utilized to increase the potency of the seed content utilized for the test. Instead, commercially offered seed content could be utilized. The seed correction must not exceed 1.0 mg/L BOD, hence care needs to be taken not to make use of far too robust a seed materials for the test. The true secret to a fantastic seed correction is a comparatively stable seed material which provides an excellent seed correction in every test condition.

Chlorine may be taken off by incorporating the sodium sulfite to the sample in adhering to method.
BOD test is performed in a temperature of 20°C. The biochemical oxygen need (BOD) could be based on subtracting the initial DO from the final DO. The Preliminary DO is recorded right away following the dilution of the sample, and any subsequent oxygen consumption in the measurement period of time is considered inside the calculation of BOD.
Be Particularly watchful that every drop is entirely combined into the sample in advance of incorporating the following. It is sometimes beneficial to hold the flask as many as a white sheet of paper to check for absence from the blue coloration.
