UV water treatment, UV air disinfection, UV sterilization. These are all common terms used when talking about what we do here. Essentially, we use UV to kill bugs and bacteria in various environments. 

So how does it work? This is the follow on question after people ask me what I do, and as an enthusiastic practitioner I'm always mindful that I don't get in a position where I'm making eyes glaze over. However, I don't have that problem here so allow me to elaborate.

UV disinfection uses Mercury vapour lamps (sometimes with doped quartz, sometimes not depending on how long they're made to last for) to produce monochromatic (or very close to) 254 nm UV-C light. The amount of UV light needed to give a set dosage to kill a specific bacteria...

Ultraviolet (UV) light can be used in many different ways. However, we are only interested in the UV-C spectrum as that's what we use to mitigate bacteria growth in air and water treatments. Here, we will look at and explain exactly what UV light does to the bacteria during the air and water disinfection process.

What is UV light?

Ultraviolet (UV) light is just part of the electromagnetic spectrum. The word Ultraviolet is derived from the Latin word “ultra” which means beyond, and the colour violet, which is the last colour in the visible section of the electromagnetic spectrum. So Ultraviolet simply means the next thing after violet.

Ultraviolet light is emitted by the sun in huge doses but is absorbed to the Earth's atmospehere to a large degree. However, recreating this type...
