The water reaching your homes is polluted with various impurities including chemical and biological contaminants. It needs to be purified before consumption, which is why you need to install a water purifier at home. If the water reaching your homes contains both a high concentration of TDS (Total Dissolved Solvents) and biological contaminants, then you need to use an RO filter. Whatever advanced water purifier you use, you will always find that they contain UV filtration for final stage purification. Read on to find out what makes UV filtration the most effective method for final stage water purification.
Why Is UV Filtration Required?
UV filtration is one of the best and most cost-effective ways of purifying drinking water from the biological contaminants. UV rays can get rid of all sorts of waterborne biological contaminants be it bacteria, viruses or moulds. It also eradicates the pathogenic disease-causing microorganisms like cryptosporidium and giardia. Furthermore, UV filtration is the best way to eradicate viruses like hepatitis virus, which show high resistance even when treated with chlorine.
How Do UV Filters Work?
The working process of the UV filter is very simple. UV rays penetrate through the microorganisms present in the water and attack their genetic core (DNA). The harmful microorganisms present in water are thus rendered sterile.
Why Is UV Filtration Used in Final Stage Purification?
Water that is disinfected using UV rays should be used right away without further purification. This is one of the most important reasons why UV filtration is used in the final stage of purification. This ensures that the water coming out of the faucet is 99.99% free of any active virus, bacteria and protozoan cysts.
UV filtration alone is not effective in most of the cases as the water you get at homes today has multiple contaminants in it. The UV radiation works only on the microorganisms. Furthermore, in case of water with sediments or turbid water, UV rays don’t prove to be efficient because they cannot reach the microorganisms present in such water. This is also one of the reasons why UV filtration is used at the last stage of purification. Before UV purification, water undergoes the other purification stages.
How Effective Is UV Filtration?
UV filtration is very effective and can eliminate nearly 99.99% of the bacteria and viruses present in water. These microorganisms are the reason behind a lot of waterborne diseases like Typhoid, Gastroenteritis, Cholera, Hepatitis and Flu. This purification method can be used for purifying water coming from varied sources like well, lake, spring and municipal supply.
Hope the above explanation gives a clear picture of why UV filtration is highly effective when used in the final stage of water purification process. It’s not surprising that this method of purification is one of the best ways to get rid of the harmful microorganisms present in water. Even the most advanced water purifiers of today integrate UV filters in the last phase of purification.
