What does a UV water purifier mean?

A UV water purifier employs the powerful disinfecting force of the ultraviolet radiations to destroy the pathogens in the water supply.

The rays penetrate the harmful contaminants and destroy them at the core.

UV purification is particularly effective against biological pollutants like bacteria, viruses, and other microorganisms by targeting them at the genetic level to kill them.

In a UV water purifier, the contaminants are exposed to the germicidal wavelength of 245-nm so that the pathogens are disrupted and can no longer reproduce.

The dosage of UV will depend on the energy delivered to the contaminated water.

The UV ray’s strength will be strong enough to neutralize all microorganisms in the water, depending on the level of contamination and the energy produced at one point.

The delivery of UV rays typically happens with the help of a UV lamp encased within a glass sleeve, and the entire setup is in a chamber.

The glass allows the rays to pass through unfiltered and, at the same time, protects the lamp from water exposure. The UV lamp is powered with the help of mercury.

Summarily, UV purifiers are safe and easy to maintain. They kill 99.99% of living organisms, and since there is no filter, there is no water wastage!
