How does UV light work to purify water?
How a UV water purifier works. A UV water purifier exposes living organisms, such as bacteria, viruses, or cysts (like Cryptosporidium and Giardia) to a germicidal ultraviolet wavelength. With enough energy, UV radiation at the 254-nm wavelength disrupts the DNA in pathogenic microorganisms so they cannot reproduce.

What is Inside a UV Water Purifier?
It’s a really simple system that pumps water past a UV light and out the other side. By the time the water leaves the light tube, any microorganisms inside of it are now dead or weakened and the water is safe to drink. I’m going to go through each of the nine parts one by one and explain what it is. By the time you finish this section, you will have a solid understanding of what the components are and how they work together.
What is the magic of UV light?
The UV Chamber is where the magic happens. The water is pushed through a pipe. In the middle of the pipe is the UV light bulb which blasts the water with UV light killing all the bacteria and viruses in it.
What Sort of Microorganisms does UV Light Kill?
Pretty much any microorganism will be severely weakened and/or killed by UV light at least to the point where it won’t be able to cause you to get sick if you ingest it. Some common illnesses that can be avoided by using a UV water purification system are:
What happens if UV levels drop below threshold?
The higher-end UV purification systems will have a sensor that monitors the level of UV radiation being exposed to the water. If the levels drop below a threshold an alarm will sound and/or the system will shut down. For systems that are critical like those found in municipal water treatment centers, these sensors are key in making sure the water is being treated correctly .
What is an inlet in a water system?
Inlet. The inlet is a fancy term for “where the water comes in”. Typically water will be pumped or forced into the system with pressure. The inlet will have a valve of some sort to allow the operator to open or close the flow of water.
What is a dimming ballast?
Dimming ballasts are special ballasts that , when used together with a dimmer, will vary the light output of a lamp. – Regency Lighting. The ballast is responsible for getting the correct amount of power to the light for proper function.
