In recent years, we have seen an increase in the use of UV light in the dentist, doctor’s office, and other locations where microorganisms may be lurking. A UV light system is an effective way to purify the incoming water to make it safe for drinking and cooking. In this article, we will take a closer look at how UV water purification works to help you make informed decisions.

How Does a UV Water Purifier Work?

These systems can purify water with germicidal UV light to make the water safe for consumption. A UV water purifier only removes microbial threats, it cannot remove other contaminants, such as chemicals, heavy metals, pharmaceutical byproducts, and other threats. When we consume water that contains microorganisms, including bacteria, viruses, cysts, fungi, parasites, and others, we put our health at risk.

UV light operates on a wavelength that scrambles the DNA of microorganisms that may be lurking in your drinking water. Ultraviolet light has a wavelength of 254 nm, which disrupts the DNA of microorganisms. The UV light doesn’t kill the pathogenic organisms outright; it actually damages the reproductive systems of the microorganisms. The primary threat of these organisms is their ability to replicate quickly to make people and animals sick. So, if they cannot replicate, they are rendered harmless and inactive, which protects our health.

What Will UV Purification Remove?

The UV purification process can deactivate a wide variety of potentially harmful organisms, including algae, cholera, E. coli, hepatitis B, streptococcus, salmonella, dysentery bacilli, giardia, cryptosporidium, mycobacterium tuberculosis, and more.

What About Public Water Treatment?

If you receive city water, you may believe that you don’t need a UV purification system in your home. The standard water treatment method is chlorination, but in recent years chlorine byproducts have become a cause for concern. Another problem is that some people are sensitive to chlorine, and they dislike the taste. This may be especially noticeable if you live closer to the water treatment plant because they add extra chlorine to boost the efficacy in outlying areas. It’s also important to note that any breaks in the water supply network may allow microorganisms to enter the water after treatment. Our water infrastructure needs significant investment, and it may be prudent to add an extra layer of protection to secure clean and safe drinking water for our homes.

Is UV Water Purification Safe?

Yes, the UV lamp is located in a quartz sleeve to ensure that the lamp doesn’t come into contact with the water. The germicidal light operates on a UV-C radiation wavelength that is not harmful if the bulb is not looked at directly or touched when it’s lit. Although the UV lamps contain mercury vapor, this is loaded in small beads that are vaporized, and no direct contact is possible without breaking. The entire system is protected with one or two tight O-rings to keep the water away from critical systems.
