ozon

Ozone in Wastewater Treatment The discharge of sanitary and industrial wastewater into the environment gradually contaminates groundwater aquifers and significantly contributes to the spread of infectious diseases. Due to ozone's high disinfection power and its ability to remove viruses, bacteria, and various microorganisms, it is considered one of the suitable options for treating sanitary wastewater. Moreover, the presence of numerous minerals, organic materials, and metals in industrial wastewater is highly detrimental to nature, making it absolutely necessary to treat them before they enter the environment. Ozone plays a crucial role in the treatment of industrial and sanitary wastewater by oxidizing metals and organic compounds, converting COD to BOD, removing BOD, and deodorizing the water. It is worth noting that using this unstable substance in wastewater treatment significantly enhances the efficiency of carbon filters. Applications of Ozone in Water and Wastewater Treatment Ozone's substantial impact on various pollutants in water and wastewater and its high disinfection power have made its use widespread in countries like Australia, Sweden, USA, Canada and India. The most important applications of ozone include: • Eliminating unpleasant odors, colors, and tastes in water • Removing bacteria and viruses in sanitary water and wastewater • Removing heavy metals in industrial water and wastewater • Oxidizing organic materials present in water • Increasing the coagulation and flocculation speed of suspended particles in water Water disinfection is used to eliminate pathogenic microorganisms, aiming to reduce waterborne diseases. The most common method for disinfecting water is the use of chlorine and its compounds. However, other methods are also available, such as ozonation, ultraviolet rays (UV lamps), etc.
