commercial water disinfection system is designed to ensure safe and potable water for large-scale applications. It employs advanced technologies such as ultraviolet (UV) irradiation, ozone treatment, or chlorine disinfection to eliminate harmful microorganisms, including bacteria, viruses, and protozoa. UV systems use high-intensity light to disrupt microbial DNA, preventing replication. Ozone and chlorine are powerful oxidizers that destroy contaminants effectively. These systems are essential for maintaining high water quality in commercial settings like hotels, restaurants, and industrial facilities. They help prevent waterborne diseases and protect equipment from microbial damage, ensuring a safe and reliable water supply for various uses.
