UV light provides rapid, effective inactivation of microorganisms through a physical process. When microorganisms are exposed to germicidal wavelengths of UV light, they are instantaneously rendered incapable of reproducing and infecting. The process adds nothing to the water but UV light, has no impact on chemical composition or dissolved oxygen content, and does not create by-products.
Industrial wastewater is a great source of potentially dangerous contamination. In order to protect the natural environment, such as rivers, lakes, beaches, and coastal areas, increasingly stricter regulations have been implemented to limit the release of pathogenic microorganisms originating from industrial discharge. This has led many large-scale manufacturing facilities to implement UV as part of their wastewater treatment process.
The main reason UV has become a preferred solution compared to its alternatives is that it doesn’t create any chemical by-products. This is exceptionally important as discharge water is usually already filled with toxic chemicals. UV disinfection is also the most effective solution against almost all known pathogenic bacteria and viruses as well as chemically complex compounds.
