UV Disinfection Systems

Ultraviolet (UV) light is a type of radiation that can be found in the electromagnetic spectrum and is measured in nanometers (nm). According to wavelength, ultraviolet can be categorized into UVA, UVB, and UVC, of which UVA can be divided into UVA-1 and UVA-2. UVA-1 causes sagging of the skin and melanin deposition, while UVA-2 and UVB burn the skin. The UV-C ranges between 200nm and 280nm. Because of its short wavelength and high energy, the UV-C band can destroy the DNA and RNA of bacteria, viruses, fungi, and other microorganisms, thus rendering them biologically inactive. Over the past two decades, UV disinfection technology has been a star performer in water and air treatment, in part because of its ability to provide treatment without the use of harmful chemicals.

UV lamps can be divided into polarized lamps, induction lamps, and LED lamps. UV polarized lamps are UV lamps with electrode materials at both ends, consisting of quartz glass tubes, electrode materials, metal brackets, and lamp heads, including mercury lamps and metal halide lamps. In the case of the positive and negative electrodes of the lamp being energized, the arc excites the metal elements inside the lamp, and the metal vaporizes to produce UV light. The greatest difference between induction lamps and electrodes is that induction lamps do not have electrode materials at both ends. The whole lamp is made of high-purity quartz glass filled with rare metals and inert gases, consisting of a high frequency generator, coupler, and bulb. The electromagnetic field through the high-frequency generator is coupled inductively into the lamp, ionizing the gas inside the bulb, and forming a plasma. The plasma radiates UV light as it returns to its base state. UV LEDs are ultraviolet output light-emitting diodes. A light-emitting diode is a solid-state semiconductor device capable of converting electrical energy into light. The greatest advantages of UV LEDs are their long life, energy efficiency, and single-band output.
