Water Treatment: The Pros and Cons of Utilizing Ultraviolet Rays



For many families today, staying in good health is top priority, leading to a choice of utilizing a water treatment system in their homes.

Irrespective of where the water comes from—either from a municipal water system or a private well—having a whole house water treatment system can be crucial to the health status of your water supply.

There are several different options to choose from when selecting a suitable water treatment system. However, your choice ultimately depends on your current needs, available budget, species of contaminants present in your water supply, and professional advice from your water treatment specialist on the best treatment method.

Due to the vast number of aging infrastructures in many cities and growing density of homes,obtaining water from aquifers can lead to arise in possible contamination. Giardia, e-Coli and other bacteria and organic organisms have been discovered in both municipal water and private wells.

While municipal water suppliers take several necessary precautions to meet water quality standards—with some homeowners carrying out annual test to determine their water quality—however, chlorine resistant microorganisms, like giardia or cryptosporidium can still find their way into municipal supplies and are naturally occurring organisms in water wells.These waterborne organisms have been shown to cause thousands of documented health cases every year.

However, one of the most effective treatment options that can provide contamination-free water for your family is ultraviolet (UV) technology. It has been proven to be one of the most reliable and cost-effective methods for disinfecting water, and is highly recommended in both point-of-use and whole-house water treatment applications

There are numerous benefits of an ultraviolet water filter, as it can eliminate about 99.99% of waterborne microorganisms—and also remove several other inorganic contaminants. Before you take the bold step, here are some advantages and disadvantages of UV water treatment systems—and everything else you need to know about UV water purification.

Advantages Of Ultraviolet Water Treatment

The introduction of a UV purification system into your water supply greatly enhances water purification and provides a safe solution to eliminate the numerous dangers associated with microorganisms in your water.

1.  Highly Effective – UV technology has been proven to destroy about 99.99% of microorganisms living in water.

2.  Chemical Free – All UV systems are completely chemical free as water is passed under ultraviolet light to effectively kill present organisms.

3.  Environmentally Friendly – As a rather natural water purification system, UV is a viable, environmentally friendly alternative to other methods such as chlorination, as it emits absolutely no by-products.

4.  Worry Free – After installation, a UV system simply requires annual service, leading to lesser worry in maintaining the system. Most UV systems only require an annual bulb change and an occasional replacement of the filter that protects the lamp.

5.  High Reliability – A UV water system can function for 24 hours a day, 7 days a week and 365 days a year. Its high availability ensures that your water is supply is kept safe always.

6.  Very Safe – It is quite safe to install or continuously operate as no dangerous chemicals is required during these processes.

7.  Fast – The UV system allow quick passage of water as it flows through the system without the need for a holding tank or reaction times.

8.  Very Clean – Using a UV water filter means they’ll be no dirty filters or media to dispose.

9.  Low Energy Use – UV water systems require very low energy to operate, ensuring that your electricity bills are kept at the bare minimum.

10.  Conserves Resources – The UV purification process does not promote water wastage.

11.  FDA Approved – The FDA recognises UV as one of only 4 methods approved for water disinfection.

12.  Cost Effective – While UV systems can be a bit expensive, however, their low operating cost makes them a cost-effective means for water purification.

Disadvantages Of UV Water Treatment

Despite having numerous benefits, there are some few disadvantages to utilizing UV light as a form of water treatment.

1.  Unable to remove all water contaminants – UV light is capable of eliminating only waterborne microorganisms and cannot not remove any other contaminants such as salts, heavy metals, chlorine or man-made contaminants. However, if other contaminants are present in your water, UV light can be used in addition with filtration to further eliminate these contaminants.

2.  Only effective with ‘clear’ water – UV light is only effective in the treatment of clear water and cannot be used in murky water or water that contains floating items. This is because these surfaces prevent the UV light from reaching the microorganism.

Therefore, such water should be pre-filtered before the introduction of a UV light treatment.

3.  Relies on electricity to function – All UV systems require electricity to function, meaning they are ineffectual in instances such as cases of emergency or survival needs when electricity is unavailable.

Overall, UV water treatment is an outstanding way to meet your families needs for water purification. When used in conjunction with either pre-filtration or post-filtration, UV light is an excellent method to ensure years of healthy clean drinking water for you and your family.
