Deaths due to waterborne diseases are not unusual in India. Cholera, Diarrhea, Jaundice and Hepatitis are some of the common diseases that are caused due to unhygienic water. This is because a large part of our country lacks an advanced purification mechanism that needs to be incorporated for purifying water coming from various sources. Therefore, to make water safe for drinking purpose, UV water purifiers have become a necessity in Indian households.
What is UV Water Purifier?
UV water purifiers offer one of the most effective and efficient way of purifying residential drinking water that is inflicted with microbial contaminants. UV water purifiers help in deactivating disease causing bacteria, viruses, protozoa and cysts that are almost invisible and very harmful for health. UV water purifiers are capable of inactivating 99.99% pathogens without adding chemicals or changing taste of the water.

How Does UV Water Purifier Work?
A typical UV water purifier uses a fluorescent type bulb that emits light having a wavelength of approximately 254 nanometers. A mercury vapor lamp is the most preferred source of short wave UV light that is used to kill microorganisms. These lamps are made up of special quartz glass that allows UV rays to pass through unhindered.
Due to a low pressure being created inside the lamp, the mercury gets vaporized and eventually becomes ionized. The ionized mercury, in turn, emits a high powered UV beam (of the order of 254 nm), which is the most effective germicidal range. The ultraviolet radiations deactivate bacteria and viruses by penetrating through their DNA. Because of this, these microorganisms entirely lose their ability of reproduction.
When to use UV Water Purifiers?
UV water purifiers are highly recommended for those households where bacteria and viruses are likely to be found in the water supply. Since, use of chlorine and other chemicals to disinfect water is not an option because they create toxic byproducts; UV water purifiers are advised in these circumstances. UV technology should not be used when the supply water contains heavy metals, salts, chlorine or man-made substances like petroleum products or pharmaceuticals.
