Drinking water is a precious resource that all human life depends on for survival. With our bodies constituting about 60 per cent water, it is essential for many of our natural functions, such as regulating body temperature, carrying oxygen and nutrients to cells, and dissolving minerals for absorption.
As such, its purity is crucial to good health. Drinking unclean water increases the risk of getting infected by transmissible diseases and developing other health issues, such as nausea and gastrointestinal problems. Thankfully, water purification technology has evolved significantly over the years, with UV sterilisation being the leading method used in many water purifiers in Singapore today.
What Is UV Water Sterilisation?
UV sterilisation is a disinfection system that leverages the microbial-killing properties of ultraviolet (UV) light, a type of electromagnetic radiation emitted by both natural (the sun) and man-made (UV lamps) sources. Under the right wavelength, specifically the Germicidal Frequency, which is 254 nanometers, UV light is wholly effective at disrupting a microorganism’s bodily functions and rendering them harmless and incapable of growing or multiplying any further.
How the system works
The way UV light does this is by penetrating a microbe’s body and destroying its DNA. Since the DNA is the single most important part of any living organism that dictates its function and reproductive capabilities, eliminating them in harmful microorganisms such as viruses, bacteria, and moulds means they are as good as dead.
This sterilisation process is relatively simple and completely effective due to its 99.9 per cent disinfection rate. It begins with water going into a UV treatment system, which primarily consists of the two core components called a quartz sleeve and a UV lamp within. The water is then is exposed to the lamp’s light that attacks and rearranges the genetic code of the microbes floating in it. Once they can no longer replicate, they are unable to infect any other organism they come into contact with.
Benefits of UV-treated drinking water
1. Effective with no chemicals involved
Studies have shown that UV sterilisation destroys 99.99 per cent of harmful microbes in drinking water without the need for any other cleaning chemical. A list of contaminants that UV eliminates includes, but is not limited to:
- Bacteria
- Viruses
- Coliform
- Cysts
- Giardia
- Salmonella
- Flu
- coli
- Typhoid fever
- Polio
- Dysentery
- Meningitis
- Cholera
- Infectious Hepatitis
2. Environmentally-friendly
UV disinfection systems are an eco-friendly alternative to chlorine disinfection and come with zero by-products.
3. Reliable and trouble-free
Maintenance happens only once a year in general, and the disinfection system functions 24/7 to provide safe drinking water on demand.
4. Cost-effective and clean
There are no dirty parts in the system, and only the lamp and sleeve need annual replacement.
5. Quick process
Water flows directly through the system without requiring holding tanks, often featured in tankless water dispensers.
6. Low-energy usage and conserves water
No drop of water is wasted, and the system consumes minimal power to function.
Conclusion
When it comes to drinking water, its safety is the most important aspect that everyone should prioritise at all costs. Hence, UV sterilisation systems are highly efficient in eliminating virtually all microbes in drinking water is indispensable to achieving safe and healthy drinking water.
