What is one alternative method to chlorination for disinfection?

Ultraviolet (UV) light is a well-established alternative method to chlorination for disinfecting water. The process involves exposing water to UV light, which effectively destroys pathogens by disrupting their DNA and preventing them from replicating. This method is highly efficient at inactivating bacteria, viruses, and other microorganisms present in wastewater or drinking water, making it a popular choice for disinfection.

UV disinfection has several advantages, including the absence of any chemical residuals in the treated water, which can be a concern with chlorination. It also acts quickly and does not create harmful byproducts that can occur when chlorine reacts with organic material in water. These attributes make UV light a valuable option for ensuring water safety and quality in various treatment applications.

Other alternatives, while also effective in their own right, either serve different purposes or come with specific limitations that influence their applicability as standalone disinfection methods. For instance, ozonation is another effective disinfectant, but it may introduce ozone residuals that can persist in the treated water.
