2. Disinfectants Post-treatment, it is crucial to disinfect the treated effluent to eliminate harmful pathogens. Chlorine, ozone, and ultraviolet (UV) light are commonly used disinfectants in STPs. Chlorination, while effective, requires careful management due to the formation of potentially harmful by-products. Conversely, UV disinfection offers a chemical-free alternative, reducing the risk of toxic residue but necessitating thorough filtration of water before application.
Sulfamic acid, with the chemical formula H₃NSO₃, is an interesting and multifunctional compound widely used in various industrial applications. This colorless crystalline solid is known for its high solubility in water and its relatively low toxicity compared to other acidic compounds, making it a useful choice in various settings.
