Definition:
A water purifier is a device for removing unwanted substance such as bacteria, germs or harmful chemicals from drinking water, thereby purifying it. The method used to purify water to make it fit for human consumption includes filtration, sediments, distillation, biologically active carbon, flocculantion , chlorination and the use of reverse osmosis and ultra Violet light.

Working:
Water purification through UV is an effective method for disinfecting water for consumption. UV system destroy harmful microorganisms without adding Chemicals are changing the water taste or odour. The UV spectrum includes wavelength from 2000 to 3900 and angstrom units. In a typical operation, water enters the inlet of a UV lamp and flow through the annular space between the qartz sleeve and the outside chamber wall. The irradiated water leaves through the outlet nozzle.

UV purification itself is not enough to purify water down to drinking water purpose as it is only effective for treating bacteria and viruses. To eliminate contaminants such as chlorine, heavy metals etc., UV system are oftained paired with reverse osmosis are activated charcoal to complete the purification process.
