What exactly is a UV disinfection system and how does it work?
The UV Disinfection System is a highly effective method of combating microbial contamination in water. However, in order to effectively disinfect the water, microbes must be exposed to UV-C light in the appropriate amount. UV Disinfection Systems are used in a variety of applications ranging from the purification of drinking water in individual homes to the disinfection of entire township water supplies to industrial wastewater treatment. UV water treatment is widely recognized as a safer and more cost-effective method of disinfecting water for industrial applications.
Ultraviolet light with a wavelength of 253.7 nanometers is used in UV water disinfection technology to kill bacteria, viruses, molds, algae, and other microorganisms that multiply and grow. UV disinfection technology kills microorganisms by destroying their DNA, rendering them inactive and unable to reproduce. UV disinfection technology can be used to disinfect drinking water, process water, wastewater, and surfaces. Aside from disinfection, this technology can also be used for TOC removal and Ozone destruction. There's also a UV sterilizer for hospitals, factories, and offices.
A high efficiency media filtration system and UV combination can remove contaminants before they cause an increase in operating costs, infection, or a shutdown situation. Previously, UV was used to disinfect a side-stream flow in cooling water loops. When combined with the proper separation processes, modern, high-capacity UV systems can deliver a high dose of UV to the cooling loop while also frequently turning over the entire reservoir. One significant advantage of UV disinfection is that the water cannot be overdosed.
How does it work?
UV light disinfects by penetrating microorganisms and destroying their DNA in UV water disinfection technology. Because DNA is essential for organisms' functions and reproduction, destroying it prevents the organism from being active and multiplying. UV energy (wavelength 240-280 nm) is naturally present in very small amounts in sunlight. The same energy is produced at higher intensities by high mercury discharge lamps, also known as UV lamps.
When exposed to the appropriate dose of UV light, no bacteria, viruses, molds, or their spores can survive. As a result, UV is regarded as the best solution for water sterilization, and a UV mobile sterilizer machine can be used for room sterilization.
Filtration systems for high-efficiency media
Cooling towers are being used by an increasing number of technology industries to remove excess heat from buildings or processes. Server farms and server clusters are typically located between system switches and routers; heat removal from these facilities is critical to their optimal performance. Server farms process advances in cluster computing, scientific simulation (such as Computational Fluid Dynamics), the rendering of detailed 3D images for health care, and the complex transactions required by web enterprises. The cooling capabilities of the building, rather than its processing speed, limit server performance. In many cases, 50 watts are required to cool the server for every 100 watts used to power it. Performance per watt is a critical design parameter for these large and complex continuous systems. As a result, effective and continuous cooling is critical for server performance.
A cooling system will typically turn over the entire volume of water several times per hour. A typical reservoir could hold 7,000-15,000 gallons and filter at a rate of 500 to 1,000 gallons per minute. A cooling tower of 100 tonnes would recirculate cooling water at a rate of 300-500 gallons per minute. Side-stream technologies are less expensive but less effective at disinfecting the cooling system. Full flow automated disinfection is required for process critical applications such as server farms, which must operate 24 hours a day, 365 days a year.
