摘要: The antimicrobial activity of ozone (OZ) and chlorine dioxide (CD) is difficult to determine, not only due the short inactivation times, but also because concentrations disinfectants decrease during reaction time. These difficulties were avoided by designing a continuous flow reactor, where steady state agents as well microorganisms can be obtained, depending on velocity. From velocity, time necessary for 99.99% reduction corresponding Ct values derived. This was done at different E. coli, L. Qineumophila, B. subtius pH 6 8 5°C 15°C, Coliphages MS 2 PhiX 174 5°C. rates obtained this way are rather compared results other authors. with increasing OZ CD (n> 1), except subtilis. relative susceptibilities are: subtilis < coll pneumophila 2. greater susceptibility Legionella coli confirmed in batch test. proved more efficient higher temperature pH. were: coli. seemed somewhat effective lower temperature, while resulted faster destruction.
