Photoscience UV sterilizer technology is a non-chemical method of disinfection that is gaining acceptance. UV kills all known corrosive microorganisms, including various bacteria, viruses, yeasts and fungi (and their spores). This method is a low-maintenance, very environmentally friendly disinfection technique that avoids the use of disinfection chemicals while ensuring high levels of disinfection. Achieving increasingly stringent hygiene standards for products in the food and beverage industry is a real challenge. If there is a need to improve production plants and equipment as a result, immediate results need to be produced, and product quality needs to be significantly improved. For manufacturers looking to improve the quality of their finished products, UV technology is an economical and practical option. UV disinfection of drinking water has been widely recognized and adopted around the world. UV germicidal lamps for water treatment have also been widely used in high-purity occasions, including pharmaceuticals and microchip manufacturing. High-quality water in these industries plays an important role. important role.
The mechanism of action of UV disinfection
Ultraviolet light is an electromagnetic wave between visible light and X-ray, and its wavelength is between 185 and 400 nanometers; one part of ultraviolet light (the part of UV-C) has strong sterilization ability, and the disinfection efficiency reaches its peak at 265 nanometers. Ultraviolet rays in the above wavelength range can kill microorganisms. The principle of ultraviolet sterilization is to penetrate the cell membranes of microorganisms and destroy their DNA, so that they cannot reproduce, so as to achieve the purpose of effective sterilization.
A typical UV disinfection system for the production of water or liquid ingredients consists of a UV illuminator with a quartz shield mounted in a cylindrical stainless steel chamber. One end of the cavity is filled with the liquid to be treated, allowing it to flow through the entire cavity. Virtually any liquid flowing through the treatment unit can be effectively U-sterilized, including raw tap water, filtered process water, high viscosity syrups, beverages and effluent.
There are currently two main types of UV technology, the difference being the type of UV lamps: low pressure (LP) and medium pressure (MP). Low pressure UV lamps are monochromatic UV spectral output (limited to a single wavelength of 254 nanometers), while medium pressure lamps have polychromatic UV output (output wavelengths between 185 and 400 nanometers).
Compared with other disinfection methods, UV disinfection has many advantages. Unlike chemical treatments, UV light does not introduce toxins or residues in the water produced, nor does it alter the chemical composition, taste, smell or pH of the liquid to be disinfected.
Photoscience UV Sterilizer treatment can be used as the main method of water disinfection, or as an addition to other water purification methods: such as carbon filtration, reverse osmosis or pasteurization. Because UV disinfection does not produce any residue, the best place to install the treatment system is at the end of each treatment unit. This not only destroys the growing microorganisms, but also minimizes the possibility of contamination during processing.
