What is one benefit of using UV light for wastewater disinfection?

Using UV light for wastewater disinfection offers the significant advantage of not leaving harmful residuals in the treated water. Unlike chemical disinfectants such as chlorine, which can form potentially hazardous by-products and leave residuals in the water, UV disinfection works by using ultraviolet light to effectively inactivate pathogens without adding any chemical substances. This is critical in ensuring that the effluent water does not pose risks to human health or the environment.

While other benefits of UV disinfection may include aspects such as speed and effectiveness against a broad range of microorganisms, the absence of harmful residuals is particularly advantageous in maintaining water quality, especially when the treated water is reused or discharged into sensitive natural waterways.
