Purification of water with Ultraviolet treatment is internationally accepted and time-tested technology. UV technology is widely used in pharmaceutical plants, mineral water plants and hospitals. Ultraviolet rays of 253.7 nanometer wavelength cause irreversible breakdown of DNA (genetic material) of bacteria leading to cell death. If the system is properly calibrated for adequate contact time and dose then the UV rays of aforesaid intensity kill / inactivate all water-borne disease-causing bacteria and viruses.
