Ultraviolet technology can be used in the water sterilisation/disinfection process.
UV irradiation can be used for multiple purposes in water treatment, but is primarily employed as a disinfection process that kills water borne pathogens without chemicals.
A major advantage of UV treatment is that it is capable of disinfecting water faster than chlorine without cumbersome retention tanks and harmful chemicals. UV treatment systems are also extremely cost efficient!
There are many more advantages of treating water with ultraviolet over other disinfection methods such as:
Cost-Ultraviolet is cheaper than other methods such as chlorine and ozone.
Ease of Use– There is no need for holding tanks, application is immediate.
Economical– Hundreds of gallons may be treated for each penny of operating cost.
No Chemicals– Ultraviolet irradiation does not use any chemicals to clean water so there are no harmful bi-products and less waste disposal, which is more environmentally friendly, safer and reduces process time.
Minerals– No beneficial minerals are removed, drinking water stays organic (No change in taste, odour, pH or conductivity nor the general chemistry of the water).
Effectiveness– It is thought that UV is more effective against viruses than chlorine.
