Ozone disinfection is a powerful method for inactivating pathogens in wastewater. However, ozone can react with natural organic matter (NOM) and other constituents in the water to form disinfection byproducts (DBPs), some of which are regulated due to potential health concerns. Optimizing ozone dosage is crucial to achieve effective disinfection while minimizing DBP formation. One key operational consideration is to determine the minimum ozone dose required for adequate disinfection. This involves conducting bench-scale or pilot-scale studies to determine the ozone demand of the wastewater. The ozone demand is the amount of ozone that is consumed by reacting with various constituents in the water before disinfection can occur. Overdosing with ozone can lead to increased DBP formation without significan....
