Ultraviolet Water Purifiers :
Ultraviolet Water Filters Kill Bacteria & Viruses
UV Purifiers using short wave UV light
Ultraviolet purification is often the best way to protect well water from bacteria, viruses, algae, and fungi using short wave UV light. Water passing through the chamber is exposed to the UV light that kills bacteria and viruses listed below. A bulb that generates the ultraviolet light must be changed yearly. Chlorine is an alternative, but for serious bacteria and virus problems, UV radiation can be more effective.
Ultraviolet Water Filters Kill the Following Bacteria, Viruses and Cysts
Our UV purifiers generate 30,000 microwatt seconds/cm2 or 30mjoules/cm2 for the required flow rate. Here is a list of some of the numerous bacteria and viruses our UV purifiers kill, with the dosages required to kill them (much lower than what our units generate). You can expect eradication of 99.9% of bacteria, viruses and cysts when the proper flow rate is maintained:
| Bacteria / Virus/ Cysts | Power to kill: microwatt seconds/cm2 |
| Bacillus anthracis | 8,700 |
| Bacteriophage (E. Coli) | 6,500 |
| Baker's yeast 8,800 | 8,800 |
| Corynebacterium diphtheriae | 6,500 |
| Dysentary bacilli (diarrhea) | 4,200 |
| Escherichia coli (diarrhea) | 7,000 |
| Hepatitis | 8,000 |
| Influenza | 6,600 |
| Legionella pneumophilia 3,800 | 3,800 |
| Mycobacterium tuberculosis | 10,000 |
| Poliovirus (poliomyelitis) | 7,000 |
| Pseudomonas aeruginosa | 3,900 |
| Salmonella (food poisoning) | 10.000 |
| Salmonella paratyphi (enteric fever) | 6,100 |
| Salmonella typhosa (typhoid fever) | 7,000 |
| Shigella dysentariae (dysentery) | 4,200 |
| Shigella flexneri (dysentery) | 3,400 |
| Staphylococcus epidermidis | 5,800 |
| Streptococcus faecalis | 10,000 |
| Vibro commo (cholera) | 6,500 |

Sterilight Residential Silver Series Point-of-Entry UV Purifiers from Viqua®
Manufactured by Viqua®, the Silver Sterilight® point-of-use ultraviolet purifiers can be used alone, or with combined with other filter configurations (see our full line of filters). The stainless steel chamber has 1/4" MNPT ends. It carries a 7 year warranty on the chamber, 5 years on hardware, and 1 year on bulb.
The water chamber has 3/4" MNPT ends. The control module can be installed near the uv light and requires AC power. The monitor sounds an alarm if the UV lamp fails. Available in 5 gpm, 8 gpm and 12 gpm flow rates. Sterilight purifiers offer a 7 year warranty on the chamber, 5 year on hardware. The bulb must be changed yearly.
Because the UV chamber needs to be clear, we recommend at least 5 micron sediment pre-filter to protect the chamber. Iron should be 0.3 ppm or less, and hard water that is over 7 grains should be softened.
