The disinfection of urban effluents is an excellent strategy to preserve the environment, as it protects the receiving bodies of pathogenic microorganisms and enables the use of treated effluent as a source of water for reuse. The objective of this work was to verify the efficiency of O3/H2O2, O3 and O3/UV treatments to disinfect municipal effluents and observe the effect of treatment time on the inactivation/destruction of the indicator microorganisms. The treatment was carried out for 25, 50, 75 and 100 min to verify the time required for the inactivation and the time necessary for the destruction of the indicator. A regrowth test was performed each 8 hour untin 24 hours. The results demonstrated that the time of cell destruction varies according to the treatment and that the ozone alone was the less effective in the inactivation and destruction of the indicators.
