Disinfection is critical for eliminating pathogenic microorganisms from water supplies. The most common chemical disinfectants include chlorine, chloramine, and ozone. Chlorination is widely used due to its effectiveness, low cost, and the residual protection it offers after treatment. However, it can produce harmful by-products, such as trihalomethanes (THMs), which have raised health concerns. Therefore, alternative methods, such as ozone treatment and ultraviolet (UV) disinfection, are gaining popularity as they do not leave harmful residues while still effectively neutralizing pathogens.
