Introduction of Ultravoilet
Fig. 1 - UV-C in the spectrum of electromagnetic radiation.


For the past 100 years science has recognized the bactericide effects of the ultraviolet area of the electromagnetic spectrum.
The specific wavelengths responsible for this reaction are situated between 240 - 280 nanometers (referred to as nm) with a peak wavelength at 265 nm. They are known as UV-C. 

EFFECT OF ULTRAVIOLET
When a micro-organism is exposed to UV-C, the nuclei of the cells are modified, due to photolytic processes. In result, cell division and, by extension, reproduction is prevented.

What does a UV sterilizer do?
A UV sterilizer is used to control infections by stopping the spread of microorganisms through the water. It is also used in pond applications to control free-floating algae. When operated correctly, free-floating microorganisms will be killed by the UV light. Note that the organisms must be in the water that flows to the UV sterilizer.
Wellsource is able to offer Medium Pressure and Low Pressure disinfection systems. Wellsource also offers Special Ultraviolet systems, offering clients an individually tailored service to solve the most complex of disinfection problems.
Ultraviolet technology is used extensively in many industry sectors including: 
Manufacturing
Pharmaceuticals
Catering
Swimming and leisure industry
Ocean-going vessels (drinking water & ballast water)
Drinking water industry
Food and beverage production
Waste water treatment industry

Advantages:
- UV does not alter taste, odour, colour or pH of the water
- UV does not require the addition of chemicals
- UV does not import toxic by-products into the water
- UV systems are compact and easy to install
- UV systems require very little maintenance
- Running costs are often lower than those of a household light bulb
