Introduction: The safety of drinking water is a crucial issue for human health; pathogenic bacteria and viruses in poor-quality water contribute to the spread of dangerous diseases such as dysentery, typhoid fever, and poliomyelitis; ozone technology is increasingly recognized as an eco-friendly and effective method for disinfecting water from pathogens; the aim of the study is to investigate the efficiency of disinfecting pathogenic bacteria and viruses in drinking water using ozone technology and to determine the inactivation of pathogens depending on ozone concentration and exposure duration; Materials and Methods: The study used 11 strains of typhoid bacteria and 36 strains of dysentery bacteria; to disinfect with ozone, 14 mg/L of ozone was added to the water for 5 minutes, and the inactivation levels of the pathogens were studied; the sensitivity of poliomyelitis and Coxsackie viruses to ozone was also evaluated; Scientific Results of the Study: The results of the study showed that ozone inactivated typhoid bacteria by up to 99.95% and dysentery bacteria by up to 99.99%; the poliomyelitis virus was eliminated by 99.99% within 6 minutes, and the Coxsackie virus was inactivated by 99.7% to 99.9% within 15 minutes; the disinfection efficiency was high when the residual ozone concentration was approximately 0.15 – 0.2 mg/L; Conclusion: The study demonstrated that ozone technology is an eco-friendly and effective method for disinfecting pathogenic microorganisms in drinking water; the research also showed that higher ozone concentrations and longer exposure times significantly improve pathogen elimination efficiency.
