Water quality analysis provides critical information about the type and concentration of contaminants present in the water. This information is used to select the most effective treatment methods, such as chemical treatment, filtration, or UV disinfection, to remove or mitigate the contaminants. For example, if the analysis reveals high levels of hardness, a water softening treatment may be necessary to prevent scaling. Similarly, if the analysis detects high levels of bacteria, a UV disinfection system may be required to prevent biofouling.
