What is UV disinfection's sensitivity to pH and temperature?

UV disinfection is generally considered to be largely insensitive to changes in pH and temperature. This is because the effectiveness of UV light in inactivating microorganisms primarily depends on the intensity of the ultraviolet light and the exposure time, rather than on the chemical properties of the water, such as pH or temperature.

While extreme conditions in either pH or temperature can potentially affect the overall efficacy of a disinfection process, under typical operational conditions, UV disinfection systems are designed to function effectively across a range of pH levels and temperatures without a significant impact on their performance. This insensitivity allows UV disinfection to be a reliable method for ensuring water safety across varied environmental conditions.

For UV systems to function optimally, clear water with appropriate UV transmittance is important, but this does not mean that pH or temperature variations are the primary factors influencing disinfection capability. Therefore, the assertion that UV disinfection is insensitive to these variables is fundamentally correct, supporting the selection of that option.
