What is Ultraviolet Sterilization?

Ultraviolet sterilization is considered to be one of the most effective water treatment methods for disinfection. UV sterilizers work quickly in targeting and stabilizing all biological impurities found in water. Additional chemicals are not needed, therefore saving costs, including containing no danger of overdosing.

Ultraviolet or UV water sterilizer are used in water purification and treatment to make water healthier and prolong the life of water that has been treated and processed. The word “sterile” is defined as being free from living germs or microorganisms. An Ultraviolet sterilizer extraordinarily cleans water and kills bacteria and microorganisms that can be able to infest water even after it has been treated.

UV is a type of energy found in the electro-magnetic spectrum, lying between x-rays and visible light. Although we cannot see Ultraviolet light or rays, we are exposed to them every time we step out into the sun. In fact, Ultraviolet light is responsible for causing sunburns.

UV Water Purification systems use special lamps that emit UV light of a particular wave-length that has the ability, based on their length, to disrupt the DNA of micro-organisms. As water passes through a UV water treatment system, living organisms in water are exposed to UV light which attacks the genetic code of the microorganism and rearranges the DNA /RNA, eliminating the micro- organism’s ability to function and reproduce. If a microorganism can no longer reproduce, it cannot replicate, therefore it cannot infect other organisms with which it has contact. This process of exposing water to Ultraviolet light is simple but effective, destroying 99.99% of harmful microorganisms without adding any chemicals to the water.

How Does UV Sterilization Work?

Many water purification systems take advantage of a UV water sterilizer even after processing their water. This is a well-known practice. Companies like Puritech highly recommend UV sterilizers as a post-treatment when treating water. Throughout the year’s ultraviolet technology has become well established as a chosen method for effective and economical water disinfection. Ultraviolet water sterilization claims many advantages: All microorganisms are virtually susceptible to ultra-violet disinfection.

For every penny of operating cost, hundreds of gallons of water are purified. NO additional chemicals are added and there’s no danger of overdosing. Once the water leaves the purifier, it is ready for use with no further contact time required. It has simple and easy to install and maintain. Compact units need a small space to operate and store. Ultraviolet water sterilizers deliver ongoing disinfection without special attention or measurement. There are no detections of chlorine taste or corrosion problems.

UV Disinfection System is an extremely effective way to combat microbial contamination in water. However, microbes have to be exposed to UV-C light in the proper amount in order to effectively disinfect the water. UV Disinfection Systems are used in many different applications ranging from the purification of drinking water in individual homes to disinfecting water supply of entire townships to industrial wastewater treatment. UV treatment for water is recognized as a safer and more cost-effective way to disinfect water for industrial applications

1. Ultraviolet Power Supply Unit

This is the main control of the Ultraviolet system. Some systems have a very simple controller, and others have a more complicated system that includes alarms, lamp change timers, trouble indicator lights, and more. Although Ultraviolet units vary in complexity and size, all controllers do basically the same thing of controlling the electrical output of the lamp and powers the UV-C light needed for water purification.

2. Inlet for untreated water

3. UV System Housing

This part of the system contains the Ultraviolet sleeve and lamp, and also controls the flow of water through the system.

4. Outlet for treated (clean) water

5. UV Bulb

The lamp of a UV system produces UV-C, which is Ultraviolet light considered to be germicidal. However, different lamps perform different functions, so the type of lamp used will be contingent on the application and disinfection requirements.

6. UV Quartz Sleeve

The quartz sleeve is made of quartz glass and is there to protect the UV lamp which is powered by electricity from the flow of water. The UV lamp transmits light through the tube into the water. It is important to clean the sleeve (generally when the lamp is changed) as minerals and contaminants in the water can cloud the glass tube.
