Ultra Violet (UV)

 

 

 

 

What does it do?

UV Light Water Systems kill bacteria.

Differing types of micro-organism can be more or less sensitive to UV light. This may be because of their cell wall structure, the presence of UV absorbing proteins or the structure of their nucleic acids. 

The PWEL UV lamps kill at least 99.9% of the water borne contamination at the specified flow and transmission rates. UV is a proven method of controlling microbiological contamination.

 

What are the benefits?

Some of the features offered by UV as a process are;

  • Microbiological control can be achieved where chemicals cannot be used.
  • Very effective against planktonic bacteria
  • No residual left in the water
  • Non-corrosive
  • Low operating cost
  • Instantaneous in line treatment
  • Does not affect pH, odour or taste


 

Where are they used?

UV is an ideal process for;

  • Potable water, particularly stored potable water
  • Point of use applications such as showers
  • Spray systems such as environmental chambers
  • Vending machine make-up
  • Water features
  • Air handling units incorporating spray humidifiers*
