A UV water purifier treats micro-biologically unsafe water with germicidal ultraviolet light. The UV wavelength scrambles the DNA of living organisms in the water, so they can no longer reproduce and make you sick. If you drink bacteria-infested water, the organisms can embed in your digestive tract and replicate.
What is difference between RO and UV?
For example, UV filters are designed to kill bacteria and viruses while the RO filters are designed to remove TDS and dead microorganisms from the water. … However, RO membranes are able to remove them completely although they do not have the capability of killing microorganisms like the UV lamps.
Is UV water purifier harmful?
UV-C treated water is considered to be incredibly effective. It is both safe and healthy because the UV-C technique eliminates up to 99.99% of microorganisms such as bacteria and viruses. … UV-C does not cause a change in the taste or odour of the water consumed.
How does UV purifier work?
UV water purification systems purify water by using ultraviolet rays to kill microorganisms present in the water. UV rays completely kill water-borne microorganisms and prevent their reproduction by disrupting their DNA. Also, UV rays do not lead to chemical changes in the water.
What are the advantages of UV water purifier?
No need to handle potentially dangerous chemicals (chlorine) Virtually immediate disinfection (no contact tanks like chlorine) Low power consumption environmentally friendly (no disinfection by-products) No moving parts to wear out or replace UV does not change the taste or odour of the water.
Which is better UF or UV?
UV water purifier kills bacteria and viruses and delivers purified water, whereas UF water purifier blocks bacteria, viruses are remained in the UF hollow fiber membrane.

What is the maintenance cost of UV water purifier?
UV water purifiers have a very low maintenance cost. They need regular replacement of basic pre-filters (also known as sediment filters) and carbon filters. They usually cost anywhere between ₹300 and ₹500, and they should be changed every six months or one year.
What is the disadvantage of using UV to disinfect water?
One disadvantage of UV treatment is that the disinfection only works within the UV aggregate and – as such – doesn’t protect against subsequent contamination in the distribution network. In chemical disinfection, the cell membranes of microorganisms are oxidized and destroyed, which kills the organisms.
