Ultraviolet (UV) light disinfection

ULTRAVIOLET (UV) LIGHT DISINFECTION SYSTEM FOR WATER SUPPLIES

Ultraviolet (UV) light disinfection systems can be an effective bacterial control and water sanitizing technology.

HOW ULTRAVIOLET LIGHT SYSTEMS WORK

UV is a type of energy found in the electromagnetic spectrum, lying between x-rays and visible light. Although we cannot see UV light or rays, we are exposed to them every time we step out into the sun. UV light is responsible for causing sunburns on uncovered skin. Ultraviolet systems use special lamps or bulbs that emit UV light of a particular wavelength. The Ultraviolet energy attacks the genetic core of the microorganism and rearranges the DNA /RNA eliminating the microorganism’s ability to function and reproduce. If the microorganism can no longer reproduce, it cannot replicate, therefore it cannot infect other organisms with which has contact. The process is simple but effective, destroying 99.99% of harmful microorganisms without adding chemicals to the water.

 

ADVANTAGES OF ULTRAVIOLET (UV) LIGHT DISINFECTION

Ultraviolet (UV) Light Disinfection advantages:

  • Effective: Virtually all microorganisms are susceptible to ultraviolet disinfection.
  • Economical: Hundreds of gallons are purified for each penny of operating cost.
  • Safe: No danger of overdosing, no addition of chemicals.
  • Fast: Water is ready for use as soon as it leaves the purifier no further contact time required.
  • Automatic: Provides continuous disinfection without special attention or measurement.
  • Chemical Free: No Chlorine taste or corrosion problems.
  • Versatile: Capacities available from 1.5 gallons per minute to millions of gallons per day.

 

Installing an UV treatment system, or any other water disinfection system is not a substitute for proper well design and construction.  If a dug well or spring is your only supply option then look at all the treatment options before you decide what to do.  Recommended treatment process selection:
1. Obtain information about your water source and have it tested at a state or EPA certified laboratory.
2. Get your water tested at subsequently appropriate intervals as determined by you and your water treatment professional.
3. Determine which problems are associated with infrastructure deficiencies, i.e., cracked casing, no cap, improper seal, poor surface drainage, etc.  Make the necessary repairs and improvements to the system.
4. Install the necessary water treatment systems.
