Ultraviolet (UV) water treatment systems effectively inactivate microorganisms, resulting in lowering the risk of contracting illnesses. The ultraviolet light breaks down and inactivates water borne pathogens, leaving them unable to reproduce. There are several benefits of UV water treatment, here are some examples:
- No change to the taste or odor of the water
- Simple maintenance
- No disinfection by-products
- Reduce plastic bottle usage
- Environmentally friendly
- No moving parts to wear out
- Compact systems to fit in small and large places
- No added chemicals
Microorganisms such as E. coli, Legionella, Cryptosporidium, Giardia Lamblia (Beaver Fever) and many others, may be contaminating your water supply. Chemical processes such as chlorination, and physical processes such as UV treatment are options to treat your water.
UV water treatment systems are designed to disinfect viruses, bacteria, and protozoa that can be found in untreated water. As water flows through the UV reactor, it is exposed to UV-C light. During this process, the DNA of organisms are changed, preventing them from replicating and rendering them inactive.
There are many different bacteriological contaminants that can be found in drinking water, many of which are effectively treated with UV. Each requires a different level of UV energy (dose) for disinfection. For example, due to genetic differences E.coli (6.6 mJ/cm² ) will require a slightly different dose of UV light to be inactivated than Giardia lamblia or Cryptosporidium (both 10 mJ/cm²). Treating viruses can require higher UV doses that typically can be found in residential UV systems, so supplementary treatment may be required if this is a concern.
UV is a rapidly growing segment in the water treatment industry today. It is widely accepted around the globe for the treatment of microbiologically contaminated waters.
