Essentials of Germicidal Irradiation for Reduction of Microorganisms
The first documented application of UV for the purpose of disinfection was a 1910 prototype drinking water plant in Marseille, France1. Since that time, effective use of ultraviolet energy for reduction of microorganisms has spread to a wide variety of applications including drinking and wastewater, indoor air quality, food safety, horticulture, healthcare and consumer products. The list of current applications is far too long to fully list here, so the simplest summation is that UV-C technology is now widely used to effect reduction of bacteria, viruses, molds and other pathogens in air and liquids and on surfaces.
UV Lamps
UV lamps generate intense germicidal ultraviolet (UV) radiation. The peak output of our UV disinfection lamps is at 254nm. UV radiation with wavelengths between 200-280nm is called UV-C. DNA/RNA of all types of bacteria, viruses, protozoa, algae, fungi, spores, cysts, oocysts, etc. readily absorb UV-C rays. As a result, the UV lamps damage the DNA/RNA of the target microorganisms. This prevents the microorganisms from causing infections.
Quartz ultraviolet lamp for 254nm germicidal radiation.
We also offer Ozone producing UV lamps.YOUWEI Ozone generating UV lamps generate UV radiation with peaks at 185nm and 254nm. Our Ozone generating lamps are used for specialized applications like TOC reduction.
Our ultraviolet lamps are made from high purity quartz. So, they are very efficient in converting electrical energy to germicidal light energy.
YOUWEI UV lamps are matched with tuned electronic ballasts for reliable long term UVC performance.
