What are Pros and cons of UV(Ultraviolet) Water Purifier

The UV water purifiers are the most cost-effective way of protecting residential drinking water against biological containments nowadays. UV purification systems are mainly used to protect against waterborne viruses, bacteria, molds, and pathogenic disease-causing microorganisms such as giardia and cryptosporidium. Even viruses such as the hepatitis virus, that known to be highly resistant to chlorine-treated water, can be relatively easily eradicated by using UV treatment.

Why UV purifiers are effective 

UV systems are effective means the water disinfection for residential point of entry used to help disinfect the entire home. UV systems are highly recommended for homeowners who thinks any E.coli, cryptosporidium, giardia or any other types of bacteria and viruses are dissolved in the water. It is not healthy and good to use chlorine or other chemicals to disinfect water like private good owners, because they create toxic byproducts. It is very necessary to avoid drinking any water that is potentially contaminated from bacteria to protect yourself from any water-borne bacterial diseases.

When to use a UV purifier

UV water purification system is the best option if your water contains bacteria or if you want to put additional protection in the case of a natural disaster. By the time your city water plant issues a Boil Water Advisory, the water has already been contaminated. A UV system will keep your water free of harmful viruses and pathogens when the water supply is compromised. 

If you own a private well or your water is stored in a storage tank, you’ll need a UV water purifier and try not to disinfect your water with chemicals.  Ultraviolet treatment is the most effective way to remove bacterias. A Rusco spin-down filter is a fantastic prefilter for well water before UV disinfection. 

Precautions before using UV water purifier 

You have to test the water quality before you use a UV system to make sure the water does not exceed these levels:

Hardness < 7 gpg (grains per gallon)

Iron < 0.3 ppm (parts per million)

Manganese < 0.05 ppm

Turbidity < 1 NTU (nephelometric turbidity units)

UVT < 75%

Tannins < 0.1 ppm

Pros of UV water filters:

Ultimate efficiency against microorganisms

The biggest strength of UV water filters lies in their efficiency of removing bacteria, fungi, parasites, and other microorganisms that are dissolved in water. When it comes to producing microbiologically safe water, ultraviolet water filters are truly excellent. If you use right UV sterilizer systems, they are capable of inactivating all types of bacteria found in your water source, including giardia, cryptosporidium, E-coli, and other disease-causing bacteria and viruses.

Environmentally friendly

Compared to chlorine and other chemical disinfectants that are used in municipal water treatment, ultraviolet water filtration does not use any chemicals to disinfect and does not produce any chemical by-products. 

Hassle-free maintenance

UV water filters are very easy to maintain, is an understatement, as these water filters only require a UV lamp change at intervals indicated by the manufacturer. For ultimate convenience, some UV filters like the Luminor Blackcomb 5.0 UV System even have a lamp life status indicator.

Compatibility with other water filtration technologies

UV water filters can be used along with activated carbon filters or reverse osmosis water filters to get more comprehensive filtration results.

Adds no tastes or odors

UV disinfection does not use chemical disinfectant, so it doesn’t alter the water in any way, shape, or form.

No water wasted

Cons of UV water purifier 

UV filter units require pre and post-filters

To provide the best results, the water exposed to UV lights needs to be free from turbidity, as sediments or particles in water may prevent UV lights from reaching bacteria. So, a sediment pre-filter is an absolute must to remove any sediments prior to UV light exposure. 

Similarly, UV filtration can not remove chemicals and lose particles from tap water. So, to be able to remove chlorine, volatile organic compounds, or heavy metals from your water, you need to combine your UV unit with a post filter.

Heats the water

If you’re not running water and it’s sitting in the chamber, the UV lamp heats the water up.

Needs electricity to work

One of the major problems of these systems is that they require electricity to work. This means that the areas which do not have an electricity supply, these systems won’t work there. On the other hand, if the electricity supply is cut for some time by chance, then there is no storage tank to store water.

No storage tank option 

One disadvantage of UV water purifiers is that they do not have the option of installing a storage tank.  This means consumers need to fill water in external bottles.

No UV light shutoff

Another negative part with them is that there is no UV light shutoff. That means as UV light is invisible, one if unable to know whether the appliance is working or not.  If the purifier stops working, then you won’t be able to notify of the same. You may thus have to consume impure water.

Conclusion
