With the outbreak of the epidemic, you may have heard a lot about ultraviolet rays. There is an ultraviolet ray that can kill the virus, called UVC. UVC is a very effective decontamination and disinfection tool. It has been used in hospitals for many years. It is also the best way to kill viruses in water. So how does UVC work and what is the effect of using ultraviolet light to provide safe drinking water in drinking fountains and direct drinking fountains?
How does UVC work?
UVC rays have the shortest wavelength among the three main types of ultraviolet rays: UVA, UVB and UVC. This also means that UVC has the highest energy, so it can kill bacteria and viruses (such as pathogens). It is a powerful decontamination tool because it destroys the molecular bonds that bind virus and bacterial DNA. Over the years, hospitals have been using UVC to disinfect wards and surgical tools.
Ultraviolet light is a natural way to effectively clean drinking water without the use of irritating or toxic chemicals. Ultraviolet light with a wavelength of 220 - 285nm destroys about 99.9% of the key DNA of potential pathogens, thereby preventing their reproduction.
Treatment of water with UVC
UVC water sterilization is becoming a more and more popular way of water disinfection. From home systems to self-cleaning water bottles, UVC is used to neutralize potentially harmful bacteria in drinking water. Safe drinking water has attracted more and more attention from the public. We provide customers with safer and hygienic water solutions.
Water sterilization is a typical multi-disciplinary terminal application of UVC led. The technologies required for its product design include optical design, thermal design, material matching, part assembly and many other technologies. As the most mature and effective application of UV LED, water sterilization module can be divided into static water sterilization and flowing water sterilization.
Fluorescent innovative water sterilization module
Static water sterilization
Static water sterilization refers to the sterilization and bacteriostasis of the water in the water storage space (container). Because the water storage container is usually static for a long time, it will be easy for bacteria to breed and cause excessive bacteria under the condition of appropriate temperature. In view of this situation, the static water sterilization module enables it to reach and maintain a low bacterial level by regularly opening sterilization. According to the sterilization orientation of the product, it is divided into bacteriostasis and sterilization. There is no essential difference between sterilization and bacteriostasis. Its fundamental purpose is to keep the affected water sterile or low bacterial level for a long time.

Through in-depth strategic cooperation with high-quality light source manufacturers at home and abroad, Qingdao fluorescent innovation produces customized light sources according to sterilization needs, so as to achieve reasonable matching between sterilization and light sources. At present, the light source output, stability and service life of the company's products have reached the domestic leading level.
At the same time, according to the different installation conditions of different household appliances, Qingdao fluorescent has developed more than ten sterilization modules for different scenarios, such as sunflower series, submarine series, sky series and YiDianTong series. It provides module schemes of top installation, bottom installation, side installation, separate installation and non-contact installation, and gives reasonable installation scheme suggestions in combination with the situation of water tank. The installation scheme shall be simple and practical, stable and reliable, and the production and installation shall be convenient and easy to operate. Qingdao fluorescent innovation can provide static water sterilization products with installation size from 8mm to 27mm and power from 5MW to 50MW.
Flowing water sterilization
Flowing water sterilization is different from static water sterilization. Through the high-power ultraviolet radiation unit, the water body passing through the sterilization module can be sterilized efficiently and instantaneously, so that the water body passing through the sterilization module can reach a level of sterility or extremely low bacterial content.

Qingdao fluorescent innovation has developed a variety of over-current sterilization modules in combination with practical application scenarios.
It mainly includes: ultra micro over-current sterilization module, aiming at the scene where the sterilization demand is less than 500ml / min.
Micro sterilization module, 500ml ~ 1L / min
Standard sterilization module: suitable for 1L ~ 2L / min flow
Enhanced sterilization module: suitable for sterilization with flowing water of 2l ~ 4L / min
Large and extra large sterilization modules: suitable for sterilization with flowing water above 10L to 500L / min.
It is noteworthy that in order to completely solve the hidden danger of exceeding the standard of bacterial colonies in drinking water sterilization, fluorescent innovative technology has developed sterilization faucets and sterilization faucets. The sterilization function is cleverly integrated into the faucet and faucet of the water purifier (water dispenser), so as to achieve real terminal sterilization, and the inlet is after sterilization. The problem of secondary pollution has been really solved.
Safe drinking water for all
Some advances in drinking water technology help to make purified water safe for everyone:
Uvc-led technology is used for biological elimination of harmful bacteria and viruses without the use of chemicals or mercury lamps. Uvc-led can provide instant full intensity power without transferring heat to water.
Uvc-led does not contact with water, and water and electricity are completely separated. Water related accessories meet the requirements of food hygiene and safety to ensure water safety.
Uvc-led has low power and electric power less than 10W, which is a perfect combination of health and energy saving.
Choosing a water purifier with ultraviolet sterilization module can more safely ensure the health of drinking water. It can kill 99.99% of common bacteria and viruses that can cause diseases in water, so as to truly enjoy drinking water safely.
According to the sterilization and bacteriostasis demand in the field of water purification, fluorescence innovation focuses on the research and development of deep UV sterilization and bacteriostasis technology. Through the accumulation of long-term product technology research and development, experiment and application experience, it can provide a variety of sterilization schemes for water purifiers, which can better meet the sterilization and bacteriostasis demand of the water purification industry.
Qingdao fluorescent Innovation Technology Co., Ltd. has a professional postdoctoral team, focusing on the research of ultraviolet sterilization application. After years of deep cultivation in the ultraviolet industry, the company has obtained a number of national invention and utility model patents. At present, a number of sterilization module products have been put into the market.
