Abstract: Oxygen transfer in mixing process in equipment with mechanical mixing was searched. The tests were performed in a glass vessel of 30 dm³ liquid content with a loop mixer equipment. The obtained results have shown a good concordance with the values published in the literature, but at higher revolution frequencies the loop mixer exhibits better oxygen transport properties.In the case when the oxygen electrode has a long time delay, a different procedure for the oxygen transfer coefficients evaluation was proposed and the results thus obtained axe in a good conformity with the values calculated according to the method published in the literature. The measured values were elaborated into a nondimensional dependence.
