UV-C light deactivates the DNA of bacteria, viruses and other pathogens and thus destroys their ability to multiply and cause disease. Specifically, UV-C light causes damage to the nucleic acid of microorganisms by forming covalent bonds between certain adjacent bases in the DNA. The formation of such bonds prevents the DNA from being unzipped for replication, and the organism is unable to reproduce. In fact, when the organism tries to replicate, it dies.
Ultraviolet technology is a non-chemical approach to disinfection. In this method of disinfection, nothing is added which makes this process simple, inexpensive and requires very low maintenance. Ultraviolet purifiers utilize germicidal lamps that are designed and calculated to produce a certain dosage of ultraviolet (usually at least 16,000 microwatt seconds per square centimeter but many units actually have a much higher dosage.) The principle of design is based on a product of time and intensity - you must have a certain amount of both for a successful design.
The Ster-L-Ray™ germicidal lamp is a short wave low pressure mercury vapor tubes that produces ultraviolet wavelengths that are lethal to micro-organisms. Approximately 95% of the ultraviolet energy emitted is at the mercury resonance line of 254 nm. This wavelength is in the region of maximum germicidal effectiveness and is highly lethal to virus, bacteria and mold spores. Therefore, the water or air that passes through the chamber is exposed to the germicidal U.V light and the genetic material of the micro-organism is deactivated, which prevents them from reproducing and renders them harmless.
UV advantage
1. Simple and easy to maintain
2. UV is effective against all micro –organisms
3. It is a physical treatment, no chemicals required by the UV system
4. Range of size to suit different demands
5. Rapid effective and safe
6. Low capital and operation costs
7. Chlorine /Ozone /TOC reduction
Applications:
1. Residential and commercial water disinfection
2. Industrial processes
3. Municipal drinking water and waste water
4. Drinking water
5. Ultra Pure water
6. Cosmetic industry
7. Food and beverage industry
8. Aquarium water
Factors Influencing UV Effectiveness
1. The type of lamp used in the application. (Low-pressure or medium/high-pressure)
2. The length of the lamp being used. (The ARC Length)
3. The physical design of the UV's water exposure chamber.
4. The condition of the water being treated.
5. The water flow rate through the UV's exposure chamber.
