Is uv required in water purifier?
Top best answers to the question «Is uv required in water purifier»
UV purification is not necessary for a water filter, but a water filter is necessary prior to a UV system. UV systems are most effective when water is clear, so they must have at least a five-micron pre-filter to prevent living organisms from hiding behind loose particles.

The UV Ultraviolet rays penetrate the cells of bacteria, virus, cysts and destroy their ability to reproduce. Without this ability, these organisms cannot multiply and eventually die. UV water purifiers have a simple but very effective process, with the UV water purifier light killing upto 99.99% of germs in water.
UV water purifiers require electric power to run. While this is not a problem in developed countries, it can pose a challenge in developing nations, where electricity may not always be readily available, especially in rural areas. UV water purifiers also only work when the water is clear.
The best aspect of UV water purifiers is that they are compatible with water purification procedures, like Reverse Osmosis, Ultrafiltration, etc. UV water purifiers never waste any water as the RO water purifiers do. We have discussed the advantages of UV water purifiers. Here are some demerits of this purification method that are worth considering.
UV purification is the most eco-friendly way to purify water because it does not add any chemicals to your water and it does not waste any water. For ‘soft’ water which is treated by the authorities and may have been contaminated during distribution, UV treatment is very effective in purifying water at the point of use.
UV Bulb is used in water purifiers because UV rays are capable of killing the bacteria and virus in the water. RO water purifiers are capable of removing the dissolved salts from the water. UF membrane, HD Filters are used for removing the suspended impurities like dust and mud particles.
In a UV water filter system, UV (Ultraviolet) rays are used to kill the harmful bacteria from the water. Hence the water is completely disinfected from pathogens. UV water purifier is good for health because it kills all the harmful microbes present in the water without affecting the taste. Which is better – RO or UV Water Purifier?
As a water treatment technique, UV is known to be an effective disinfectant due to its strong germicidal (inactivating) ability. UV disinfects water containing bacteria and viruses and can be effective against protozoans like, Giardia lamblia cysts or Cryptosporidium oocysts.
Like any water treatment process, UV water purifiers require some maintenance. The UV lamp itself requires replacing roughly every 12 months, or after every 9,000 hours. The reason why you need to change the lamp is because after 9,000 hours, the mercury in the lamp diminishes, reducing the effectiveness of the lamp.
Ultra Violet (UV) filters: UV light (minimum level radiation) is passed on water to kill bacteria and other microbes by attacking the DNA in cells. These filters remove pesticides by up to 99%. This filter is effective in removing all types of pathogens but it is not effective for removing suspended particles, chemicals, taste, smell or colour.
