The aim of this study was to observe the efficiency of ozone transferred by an airstone bubble diffuser, using two ozone generators with different output of ozone (5 g.h–1 ‒ G1; 15 g.h–1 ‒ G2). The retention of ozone in ozonised distilled and potable water and the devitalisation effects on <italic>E. coli</italic> in the water were also noted. Ozone was introduced to two types of potable water of different composition intended for mass consumption, (MC)a and (MC)b, distilled water, and well water intended for individual consumption. The devitalisation effect of ozone on <italic>E. coli</italic> in well water (WW) and added to potable and distilled water was observed. The results of our study showed that under the conditions used, the level of ozone during ozonisation with G1 increased more rapidly in distilled water and after termination of ozonisation, the retention of ozone in distilled water was a little lower in comparison with the potable water. The devitalisation of <italic>E. coli</italic> either naturally present in the water or added to it required the level of ozone close to or equal to 0.25 mg.l–1.
