Ozonização como processo de desinfecção da água para consumo humano: eficiência e sustentabilidade. Revista Aracê, São José dos Pinhais, v. 7, n. 5, p. 24859-24879, 2025. Disponível em: https://doi.org/10.56238/arev7n5-226.https://rigalileo.itegam.org.br/handle/123456789/1191Water disinfection is essential to eliminate pathogenic microorganisms and ensure sanitary safety. Among emerging technologies, ozonation stands out due to its high efficiency and environmental sustainability. This study analyzes the effectiveness of ozone application in water disinfection in Itajaí/SC, addressing its physicochemical principles, technical-economic feasibility, and environmental impacts. The methodology combined literature review, experimentation, and case study, showing that ozonation is more effective than chlorine, especially against resistant pathogens, and reduces toxic byproducts while providing synergistic effects when combined with other methods. It concludes that ozonation is a viable and sustainable alternative for sanitation, contributing to the improvement of drinking water quality.pdf.OzônioDesinfecção da águaSustentabilidadePurificação da águaTratamento de efluentesArtigoEngenharia Sanitária
