UV Disinfection in Wastewater

Ultraviolet disinfection (UV) transfers electromagnetic energy from a mercury arc lamp to an organism's genetic material, destroying the cells ability reproduce.

UV radiation, generated by an electrical discharge through mercury vapor, penetrates the genetic material of microorganisms and retards their ability to reproduce.

The optimal wavelength to effectively inactivate microorganisms is in the range of 250 to 270 nm.

UV disinfection has become accepted as a superior alternative or supplement to conventional conventional wastewater treatment with chemicals, primarily chlorine.

Advantages of UV Disinfection

1. UV disinfection is effective at inactivating most viruses, spores, and cysts.

2. UV disinfection is a physical process rather than a chemical disinfectant, which eliminates the need to generate, handle, transport, or store toxic/hazardous or corrosive chemicals.

3. There is no residual effect that can be harmful to humans or aquatic life.

4. UV disinfection is user friendly for operators.

5. UV disinfection has a shorter contact time when compared with other disinfectants.

6. UV disinfection equipment requires less space than other methods.
