What follows after the UV light treatment in a water treatment process?

After UV light treatment in a water treatment process, the subsequent step typically involves additional filtration, including processes such as ultrafiltration. The role of UV light is to disinfect the water, effectively inactivating bacteria, viruses, and other pathogens without the use of chemicals. However, while UV treatment is efficient in removing biological contaminants, it does not remove physical particles or certain chemical contaminants from the water.

In practical applications, following UV treatment, water is often subjected to filtration to remove any remaining suspended solids or particulate matter that may have been present in the water prior to disinfection. This step enhances the clarity and overall quality of the water, ensuring it meets safety and aesthetic standards for its intended use.

Thus, ultrafiltration or a similar method is key in the post-UV treatment process for ensuring the water remains clean and suitable for consumption or other applications.
