When people are looking into ways to clean up their drinking water the options that are available can be mind-boggling. There are so many different models to look at and so much information to take in. But one type that is gaining in popularity is UV water filtration.
This type of system can be utilized on either a municipal water supply or even if your water is derived from a natural source such as a lake, stream or even a well. Many people have the misconception that well water is clean, but in many cases this is simply not the case. That’s why no matter where your water originates it is best to have it professionally tested to ensure what is present in it.
These systems work by using a UV light source, typically a lamp that is encased in a protective transparent sleeve. The sleeve is generally constructed from quartz. As water passes through the chamber it becomes exposed to the UV light. Then science takes over. When microbes become exposed, the light is absorbed into their nucleic acid and causes the DNA structure of the microbe to become scrambled. When this happens the microbe is transformed into a sterile microbe and is no longer able to reproduce, rendering it safe.
But there is one drawback to these systems. Since they focus solely on biological contaminants that are considered harmful, they typically have to be used with some other type of filtration system. These systems can range from reverse osmosis, GAC, carbon or others.
The only victims of this light are microorganisms such as molds, bacteria, yeast, algae, viruses and those categorized as oocysts. Any other materials can pass through without the light having any effect on them at all. This leaves the door wide open for chlorine, heavy metals, chemical contaminants or VOCs, or volatile organic compounds.
VOCs are chemicals that are emitted as gases from certain solids or liquids. These can include everything from paint and varnish to permanent markers. The EPA estimates that indoor contamination from VOCs can be as high as ten times that of outdoor air quality, making them a serious consideration.
UV water filtration systems are also great because their effects are not harmful or cause damage to plumbing or septic systems. Plus, they do not alter the taste of the water, nor is the pH or other properties of the water affected.
