Ultraviolet
Ultraviolet designates a band of the electromagnetic spectrum with wavelength from 10 nm to 400 nm, shorter than that of visible light but longer than X-rays. UV radiation is present in sunlight, and contributes about 10% of the total electromagnetic radiation output from the Sun. It is also produced by electric arcs and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights…
When to use an UV water system?
- Suspended Solids, both visual and not visual particulate matter (turbidity).
- Scale, fouling caused by physical scale deposits on the quartz sleeve from iron, manganese or calcium carbonate covering the quartz sleeve
- UV Absorbing Compounds, UV absorption in water is almost entirely caused by dissolved substances. ...

Do I really need a UV water filter?
Anybody who is concerned about possible or proven microbiological contamination in their drinking water should consider a UV system. Do not look to UV to remove any chemicals from water nor to improve the taste and odor of the water. It simply isn't designed for either.
Is UV water treatment worth it?
Overall, UV water treatment is an outstanding way to meet your families needs for water purification. It has been proven to be one of the most reliable, cost-effective methods for disinfecting water and is applicable in both point-of-use and whole-house water treatment applications.
What are the advantages of UV water purifier?

Compact systems available for the tightest spaces. ... Disinfects water with excellent efficiency. ... Does not affect the colour or taste of water.More items...•
Is UV treated water safe to drink?
Are UV purifiers safe? UV water treatment is safe. It does not use harmful chemicals or alter the composition of water. A UV sterilizer uses UV-C light to disinfect.
What are the advantages and disadvantages of purifying water with UV rays?
UV water purifiers definitely remove a lot of impurities but do not work on a few. For example, they do kill bacteria and viruses but are not effective on dissolved impurities such as rust, pesticides, fluoride, arsenic etc. Moreover these purifiers are not effective on muddy water as well.
What is difference between RO and UV water purifier?
For example, UV filters are designed to kill bacteria and viruses while the RO filters are designed to remove TDS and dead microorganisms from the water. The good thing about RO systems is that they use an activated carbon which enhances the taste of the water.

What are the disadvantages of UV disinfection?
DisadvantagesUV light can only eliminate the micro-organisms present in the water. ... If the water is cloudy, a pre-filter should be used. ... UV water systems require electricity to operate. ... UV disinfection does not offer the persistence of some other chemicals.
Overview
Today, everyone is careful in almost everything. Most especially on what we drink and eat. And the most basic of all is our drinking water. It has to be clean and safe for us and for our family.
What is UV Water Treatment?
Ultraviolet (UV) Water Treatment is a disinfection technology that cleans water by killing many microorganism species by exposing water to high UV light dosage.
How does UV light eliminate the cause of infection and diseases?
Microorganisms exposed to the UV light absorb it, which then destroys the organisms’ nucleic acids, DNA and RNA, both responsible for reproduction and replication. Since these microorganisms cannot reproduce, the risk of infection or disease is thus eliminated.
When was Ultraviolet Light first used in water disinfection?
Since 1916, United States has been using UV Light for water disinfection. It was later on in the 1980s to the 1990s that small-scale UV light water treatment was developed for use in many homes, small and medium scale businesses, and private water supply users.
10 Reasons Why You Need a UV Water Treatment System
UV light kills and eliminates several disease-causing microorganisms and contaminants in the water.
Disadvantages in UV Light Water Treatment
UV light disinfects by only eliminating the microorganisms present in the water. It cannot remove metals, chlorine, salts, oil or other impurities. UV light will work best if paired with other filtration methods to make sure all impurities are removed.
Why would I use UV water treatment over other methods? (using UV instead of Chlorine)
UV light water treatment and Chlorine are both approved by EPA and FDA. But these are some points that you might consider in comparing these two systems:
Why is UV disinfection used?
UV disinfection deactivates 99.99% of living organisms in the water. They are designed to run constantly to guarantee the water you use is always safe. Because a UV purifier is not a filter, there's no wastewater or debris left behind to clean out. Every drop of water that enters the UV system is purified.
What is UV water purifier?
A UV water purifier treats micro-biologically unsafe water with germicidal ultraviolet light. The UV wavelength scrambles the DNA of living organisms in the water, so they can no longer reproduce and make you sick. If you drink bacteria-infested water, the organisms can embed in your digestive tract and replicate.
How much does a UV system cost?
Like the size, the price of UV systems varies. Typically, a residential UV system costs around $400 or $500. Shop Residential UV Systems.
How long does a UV lamp last?
A UV lamp lasts about 9,000 hours or 375 days (if you run it all the time). Clean the quartz sleeve. The glass quartz sleeve that surrounds the lamp needs to be clean for the UV lamp to work effectively. Check the quartz sleeve when you change the lamp to make sure it's clean.
Why do UV lamps need quartz sleeve?
A quartz sleeve protects the UV lamp from the water because water and electricity don't mix well. One or two O-rings to seal the whole system together. UV lamps run on mercury vapor. The mercury vapor is loaded into a UV lamp in the form of little beads. Occasionally, you may see beads rolling around in the lamp.
What is UV system?
UV systems are POE (point-of-entry), which means you install them before water enters your home to purify the water throughout your house. Most of the time, typical household pressure is enough for a UV system to operate.
What is UV dosage?
UV dosage is the measurement of energy (in mJ/cm²) delivered by a UV water purifier. The more dosage provided, the more energy delivered to treat contaminated water. At a certain threshold, this energy becomes sufficient enough to inactivate most of the microorganisms present in water.
