Why do they make UV Purification Systems for Water?

Before it is delivered to our homes, water is typically subjected to a battery of rigorous inspections. This is done so they know what filters have to be put in place to purify the water and make it suitable for consumption.  Depending on where you’re located there are a variety of treatment processes that are used. On the other hand, there could be a number of mishaps or leaks that cause the water to become contaminated.

The likelihood of contamination in the water supply of homeowners who rely on private wells is multiplied several times over. The vast majority of people make use of conventional filtration systems such as reverse osmosis systems, which provide some degree of defense against contaminants. UV purification systems are the most effective filtration technology for treating bacteria.

People utilize ultraviolet lamps for a variety of objectives, including tanning, cleanliness, infection control, and infection prevention. It should therefore come as no surprise that ultraviolet (UV) lights are being utilized in the process of disinfecting and purifying water.

 UV water filters destroy microorganisms and kill 99.9 percent of bacteria in the water without the use of any chemicals. The bacteria are subjected to ultraviolet light, which causes them to go dormant since the rays break the bacteria’s DNA. This also stops the germs from growing and reproducing.

What exactly are UV filters?

A purifier known as a UV water filter disinfects water by exposing it to germicidal ultraviolet radiation to remove potentially hazardous bacteria. The microorganisms’ nucleic acid in their DNA is destroyed by the UV radiation contained in the filter, rendering the microbes incapable of multiplication and reproduction. The filters each have their specialized bulbs that emit ultraviolet light at a specific wavelength (254 nanometers). This particular wavelength generates radiation with an intensity that is greater than that which is produced by the sun.

The effectiveness of a UV water filter is determined by a variety of parameters, including the strength of the radiation, the length of exposure, and the quality of the water. When utilized on its own, this filtering system will not change the flavor, appearance, or smell of the water.

What are some things that UV systems Help Eradicate?

The majority of microbes, including bacteria, viruses, and molds, are killed by the procedure since there are no microorganisms that can withstand the effects of ultraviolet (UV) radiation.

Why should you acquire a water filtration system that uses ultraviolet light?

UV therapy systems, as compared to other treatment systems available on the market, have several distinct advantages. They are as follows:

  1. Other methods of water treatment, such as chlorination, involve the use of harsh chemicals, which alter the water’s chemical composition and impart an unpleasant flavor. UV systems do not require the use of any chemicals and have no discernible effect on the chemistry or flavor of the water because they do not employ any chemicals. In high concentrations, the chlorine will react with the other chemicals in the water, which will result in the production of hazardous compounds.
  2. UV water filters are incredibly cost-effective, and the only maintenance that is required of them is to have the bulb replaced once each year.
  3. Unlike RO systems, which remove a significant amount of water during the filtration process, UV therapy does not throw away any water throughout the treatment procedure.
  4. UV systems are environmentally benign because the filtration process does not result in the production of any by-products.
  5. They don’t have any unclean or worn-out pieces that need to be thrown away, therefore they don’t create any additional work for the user.

UV Treatment In comparison to Boiling Water

People have been boiling water to destroy microbes throughout history. Nevertheless, this procedure is not perfect and does not kill all germs. It has various limitations.

  1. The water must be brought to a boil for at least twenty minutes to eradicate all germs.
  2. Even after the water has been boiled, there is always a chance that some microorganisms have survived.
  3. After it has been brought to a boil, the water must be allowed to cool before being consumed. If care is not provided, there is a risk of reinfection.
  4. The process of bringing water to a boil consumes a significant amount of energy.
  5. The flavor of the water is altered when it is boiled.

On the other hand, the UV filtration method delivers safe drinking water that is free of 99.9% of all bacteria almost immediately. This method does not change the flavor of the water or its chemical composition, and it does not need nearly as much energy as boiling does.

A Few of the Limitations of UV Systems

There are some restrictions imposed by UV filters. The primary curtailment is that microorganisms are not removed together with other potential contaminants found in water, such as heavy metals, inorganic compounds, and salts that contribute to water hardness. They are only efficient in removing the pollution caused by pathogens. Therefore, they must be utilized in conjunction with various other water filters. The water must be brought down to a 5-micron position to adequately expose the bacteria and other microorganisms in the water.

Second, when the water is hazy or muddy, ultraviolet (UV) filtration devices do not work as well. The bacteria in the water will be exposed to a lower level of UV light because of the particles in the water, and they may even be able to hide entirely behind the suspended particles to avoid the rays.

What are the Benefits of Using UV Treatment?


A public water supply should be free from bacterial contamination in the vast majority of instances. Accidents and leaks, on the other hand, might introduce contaminants into the water supply. When anything like this occurs, the municipality in which you live will notify you to boil the water. The utilization of a UV filtration system is highly recommended at this time.

If you get your water from a private well, there is a significant risk that it could be tainted with disease-causing bacteria or viruses notably in wells that are less than 80 feet deep. Additionally, this is the ideal time to implement UV treatment; however, you may also need to implement it in conjunction with other filtering systems that remove chemical and inorganic substances from the water. You really ought to have the water from your well checked out for your protection.

If you find bacteria or other potentially harmful pathogens in your home’s water, installing a UV treatment system will be of great assistance to you. A water expert may suggest utilizing additional filtering systems in conjunction with the UV filter.

Before installing a UV filtering system, you should first consider installing a pre-filter, if necessary. Before the water is allowed to enter the UV filtration system, many systems include a pre-filter with a micron rating of 5 microns first. This is done to improve the efficiency of the ultraviolet light and the longevity of the UV filtering system by removing particles from water that is hazy or muddy. This can be accomplished by doing this.

What Kind of Upkeep Does a UV Treatment System Require?

As with any other type of water filtering system, UV filters require regular maintenance to continue operating at peak efficiency. If you want your UV system to continue protecting you from viruses, bacteria, and other infectious agents, you have to give it the attention and care it needs.

UV bulbs are somewhat different from regular light bulbs. They have a quartz exterior filled with inert gas with mercury mixed in. Mercury affects the germicidal quality of UV lights. Because the mercury will continue to run out over time, the lamp will lose its ability to destroy microbes. After one year, the lamps included in the UV filters need to be changed. They have a lifespan of approximately 9000 hours, which is equivalent to 375 days.

Before you can add another lamp, you will also need to clean the quartz sleeve that is enclosing the current lamp. This sleeve ought to be changed out once every two years at the very least.

It is highly recommended that you additionally replace the pre-filter and check the O-rings on the UV system. Even if they wear down over time, the rings continue to ensure that the seal is watertight and does not have any leaks. The pre-filter has a lifespan that ranges from six to twelve months, depending on the type of water that is run through it.

When Should You Make Use of an Ultraviolet Water System?

For more than a century, people have been successfully disinfecting their drinking water with ultraviolet (UV) light water filters. Today towns and cities all over the world including Canada, use the process in their municipal drinking water supplies.

There are several manufacturers located in North America and all across Europe that produce UV systems that are more compact and suitable for use in home settings. UV Max, UV Pure, and Sterilight are just a few of the companies that make this product.

A great number of people in Manitoba have put similar systems in their own homes, such as cabins, summer houses, and cottages, as well as in public areas like churches, community centers, and camping grounds. If you are a property owner who is considering installing a water filtration system, the issue that arises is why you should choose a UV system rather than another type.

Your decision on any purification device, much like your decision regarding other water filtration systems, should be based on the quality of your water and how the device will alter that quality. Before you can purchase a system that can address the issue with your water, you need to figure out what exactly needs to be fixed in it.

Different water purification and filtration systems have different levels of effectiveness. Some are meant to remove sediments from the water, while others are made to remove particular compounds from the water. In addition to this, various anti-biohazard devices get rid of biological contaminants. The final category is made up of UV systems.

The most efficient tools for eliminating microorganisms from water are ultraviolet (UV) light systems. The hazardous microorganisms in your water are affected by the UV rays because the rays attack their genetic code, also known as their DNA, which hinders their capacity to reproduce. This technique is not only effective but also simple to implement and kind to the natural world.

UV filters are quite useful in residential settings and have the capability of disinfecting water for an entire household. They can also be added to a reverse osmosis system and only treat your drinking water. UV systems are for customers who want to rid their water of biological contaminants that have been demonstrated beyond a reasonable doubt. They do not get rid of contaminants, nor do they alter the smell or flavor of the water in any way.

 The systems each include a UV lamp that is housed within a steel chamber that has a connection on the ether end. They also come with a ballast, which is a power supply for the lamp and is included in the package. The vast majority of household UV filters are installed on the home’s primary water supply line. Some UVs have received NSF certification, while others do not.

People who live in more remote places are typically the ones that are interested in purchasing UV water filters. In most cases, individuals begin their adventure into the murky realm of water purification by participating in a substandard water test. This may be quite an intimidating experience. Before conducting any water quality testing or installing a water purification system, you are recommended to speak with an experienced water professional.

 If you test your water, you might discover that it contains bacteria like coliform, giardia, or cryptosporidium, all of which are contaminants that should not be found in drinking water. When you consult the experts in your area,(www.affordable water treatments.com) and they will discuss your options with you.

The Problems With Chlorine

Chlorine is a powerful oxidizing agent that can cause severe damage. It will kill the tissues of any bacteria or other pathogens that are present in the water very rapidly. The difficulty, however, is that chlorine might potentially combine with other chemicals that are present in the water in its natural state to generate poisonous combinations. On the other hand, ultraviolet light does not contribute anything to the water. The sole purpose of UV light concentration is to eliminate germs and other infectious agents.

Four Things to Remember

In conclusion, in addition to maintaining the original flavor and aroma, ultraviolet filtering systems offer several other desirable benefits.

  1. UV systems do not put any harmful chemicals into the water at any point and are extremely efficient since they kill 99.9% of the bacteria that they come in contact with. The taste and flavor of the waterares not changed in any way.
  2. The energy consumption of the lamp is comparable to that of a 60-watt light bulb to keep the cost of operation as low as possible
  3. They have a low requirement for upkeep. Every year, you will only need to replace the light bulb, and check the sleeve to make sure it’s clean. Aside from that, they are the kind of system that you can just set and forget.
  4. It is important to remember that UV light is not sufficient to clean the drinking water in your home on its own. Because UV radiation can only eliminate biological impurities, the water you use will still include non-biological contaminants even after it has been treated. Impurities such as heavy metals, chlorine, or minerals that contribute to hard water have to be removed separately. You may need to install a water softener and iron remover before the UV light to take out other impurities first. To provide the cleanest and safest drinking water possible, ultraviolet (UV) light is sometimes combined with other chemical filtering methods, such as a carbon filter and a reverse osmosis system.
