Here is everything you need to know about UV Bacterial Control Technology in UV water purifier. How it works, the characteristics, efficiencies, advantages and disadvantages, maintenance, etc.
If you have a well, if you collect rainwater if you want to live independently or if you are a survivalist then you need a system to make your water drinkable. There are different methods such as chemicals, filtration systems, boiling or even the use of ultraviolet (UV) water purifier. This latest technology has interesting advantages. Discovery of this simple and efficient method of drinking water requires little maintenance and monitoring.
How Does a UV Water Purifier Work?
The principle of operation of a water purifier using ultraviolet rays is quite simple. The device will expose the organisms in the water to a specific wavelength of ultraviolet light . Indeed, if it is used with sufficient energy, UV radiation with a wavelength of 254 nm destroys the DNA of microorganisms. Ultraviolet radiation from a UV water purifier does not destroy the microbes themselves, but just their DNA. This action prevents bacteria, viruses and other parasites from reproducing and therefore becoming pathogenic for humans because it is their reproduction in our body that causes diseases.
How is an ultraviolet water purifier made?
A UV water purifier with UV Bacterial Control Technology has a chamber that encloses the entire system. The glass quartz sleeve contains the UV lamp which emits a germicidal wavelength of ultraviolet radiation to deactivate living organisms. The quartz glass sleeve is transparent to the UV wavelength, which allows UV light to penetrate the glass and disinfect the water. A quartz sleeve protects the UV lamp from water, as water and electricity don’t mix. One or two o-rings are also used to seal the entire system.
UV lamps work with mercury vapor. The mercury vapor is charged in a UV lamp in the form of small beads. Sometimes you can see beads rolling in the lamp. These beads are mercury before being vaporized to create fuel for the lamp. There are also now LEDs that can replace a UV lamp. More economical and with a longer life expectancy, LEDs are a good alternative, but only for lower powers.
Are Ultraviolet Water Purifiers Effective?
UV systems sterilize water quickly and efficiently. UV disinfection deactivates 99.99% of living organisms in the water. They are designed to work constantly to ensure that the water you use is always safe. Because a UV purifier is not a filter, there is no wastewater or debris to clean up. Every drop of water that enters the UV system is purified. However, the device requires a source of electrical energy to operate. Without a power supply or in case of a power cut, water disinfection does not take place.
UV water purifier or chlorine treatment?
Chlorine treatment is a widely used alternative to ultraviolet. However, ultraviolet treatment is much safer and easier to carry out. Ultraviolet light treats water for protozoa that chlorine disinfection is unable to remove. A UV water purifier is also much easier to maintain and safer to use than chemical disinfectants. Treating water with chlorine requires a holding tank, regular injections, and precise dosages. In fact, many wastewater treatment plants now use UV water purification to remove harmful chemical by-products from the water resulting from chlorine or chloramine treatment.
Ultraviolet water purifiers or water filter?
Reverse osmosis systems, ultrafiltration systems, carbon filters, and ceramic filters separate all contaminants from the water through the tiny pores of a filter or membrane. Unlike water filters, the UV Bacterial Control Technology does not remove particles from the water. Ultraviolet treatment purifies water by exposing living organisms to ultraviolet light, but it does not filter them. Water filters do not remove bacteria and viruses like a UV system. UV disinfection, therefore, works alongside water filtration systems to provide clean water, a true compliment and not a competing method.
