If not, smaller quantities of digester supernatant, return activated sludge, or an acclimated seed material can be employed to improve the potency with the seed content used for the test. As a substitute, commercially out there seed content may be applied. The seed correction mustn't exceed 1.0 mg/L BOD, for that reason treatment must be taken not to work with much too solid a seed product with the test. The key to a great seed correction is a relatively stable seed product which makes a good seed correction in every test scenario.
