WHAT IS A UV STERILIZER?
55 Watts UV Sterilizer – Ultraviolet (UV) light has been used to disinfect water supplies for more than 75 years, but only recently have home UV systems become available. Municipalities sometimes use UV instead of chlorination for disinfection to avoid the byproducts that chlorination may produce in the treated water supply. The primary advantage of UV treatment is that it disinfects water without the use of chemicals. Its primary disadvantage is the lack of residual disinfection.
UV water treatment devices can be used for well water and surface water disinfection. UV treatment compares favorably with other water disinfection systems in terms of cost, labor, and the need for technically trained personnel for operation. Water chlorination treats larger organisms and offers residual disinfection, but these systems are expensive because they need special operator training and a steady supply of potentially hazardous material. Finally, boiling water is the most reliable treatment method but it demands labor and imposes a high economic cost. UV treatment is rapid and, in terms of primary energy use, approximately 20,000 times more efficient than boiling.
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 electromagnetic 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 wavelength 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.
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 years, 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 ultraviolet 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.
Use of UV in water
Water Bottling Plants
- When you are in a water bottling business, you will need to consider using a UV sterilizer to make sure that you kill all the bacteria that build up in your storage tank. Every time you open your filling tap, the water goes through the UV system killing all microorganisms that can be harmful to your body.
- Who wants to cook with unsafe water? We recommend that you add a UV sterilizer to your domestic system to ensure that the water is bacterial-free and safe to consume.
Parts of the UV System
- 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.
- Inlet for untreated water
- UV System Housing
- This part of the system contains the Ultraviolet sleeve and lamp, and also controls the flow of water through the system.
- The outlet for treated water
- 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.
- 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.
- Flow Rate: 2720 LPH/12 GPM
- Inlet/Outlet: 3/4”
- Diameter: 62,5mm
- Length: 960mm
