What is UV?

UV stands for ultraviolet. It is water purification methods that kill or inactivate waterborne micro-organisms. It destroys 99.99 % of waterborne micro-organisms.

Such microorganisms include

  • Bacteria
  • Protozoa
  • Cysts
  • Cholera
  • Dysentery
  • Viruses
  • Salmonella
  • Cryptosporidium
  • Giardia

How does UV water purification work

UV water purification method uses Special lamps which emit UV light waves/ rays which are also called frequency. The unique lamp is surrounded by clear Quartz sleeve which prevents direct contact with water and prevents short circuits.

Water passes through the special lamps that emit UV light frequency. This UV light frequency penetrates through microorganism DNA code, attacks, disrupts and rearranges microorganism DNA code causing them to become inactive and stop reproducing further.

The best frequency used to kill germs is 254 nanometer (nm).

Most of the people fear this method because of exposure to ultraviolet rays which they believe cause cancer. The method is approved to be safe for human consumption because the process of exposing water to ultraviolet rays is done in an enclosed container causing no risk to the human being.

Also, it is safe since you don’t add chemicals to clean water.

Common components that are used in the ultraviolet method include:

  • Sediment pre-filter – removes particulates such as sand, silt, and rusts.
  • UV reactors chamber-where the quartz sleeve is stored and untreated water enters the chamber. The water is purified as it runs through the UV reactor chamber
  • UV quartz sleeves it is where the lamp is stored and ensures high transmittance for the ultra-violet and protects UV lamp from short circuits.
  • UV lamp -it emits Ultraviolet
  • Electronic ballast –controls the electric output to the lamp and powers it to produce ultraviolet light.

Tips on how to choose UV water purifier

Water Contaminant

It is essential to know contaminants present in your water. For UV water purifier to work effectively, they are a certain parameter that your water must meet otherwise you need to install pre-filter. Such parameters include:

  • Hardness < (less than)7 grains per gallon
  • Iron < (less than) 0.3 parts per million
  • Manganese <(less than) 0.05 parts per million
  • Turbidity < (less than) 1 NTU
  • Tannins < (less than) 0.1 parts per million
  • UV Transmittance > (greater than) 75%

Note it is necessary to pre-filter your water and remove contaminants such as sediments and other particulates for the UV water purifier to work effectively.  Also, the sediment and other particulates can create a shadow which prevents UV rays from reaching harmful contaminants. If you have other water filters, the UV water purifier is installed last.

UV system flow rate

The flow rate is how much amount of water can flow in the system. The UV water purifier measures rates in gallon per minute (GPM).  The water may not be adequately treated, If you undersize the flow rate. The best thing is you oversize the flow rate.

1 Bathroom requires 6 gallons per minute flow rate

2 Bathrooms need 9 gallons per minute flow rate

3 Bathrooms want 12 gallons per minute flow rate

4 Bathrooms require 15 gallons per minute flow rate

5 Bathrooms need 18 gallons per minute flow rate

Amount UV energy from the lamp

For specific contaminants to be inactivated, it requires a particular dose or energy from the UV lamp. The energy is measured using millijoule per square centimeter or mJ/cm2.

Contaminants such as E. Coli, Giardia, and Cryptosporidium typically require a UV dose/ energy of 10 mJ/cm2 to become inactivated.

Most UV water purifier certified by NSF “A” is rated at 40 mJ/cm2 and are best used for commercial application.

The most accepted standard is 30 mJ/cm2

Added features

There is UV water purifier that has LED indicator informing when the filter is supposed to be replaced. Some brands come with a flow meter, touchscreen display, and shut-off valve.
