What are the sterilization methods for stainless steel reverse osmosis ultrapure water equipment? Author: stainless steel reverse osmosis ultra-pure water equipment because of water to meet the water needs of many industries, it is used in the industrial production more widely. Users who are familiar with stainless steel reverse osmosis ultrapure water equipment know that stainless steel reverse osmosis ultrapure water equipment mainly relies on a booster pump to smoothly enter the reverse osmosis membrane for deep purification. If the water pressure of the equipment does not reach the specified Standards will also affect the output and quality of the water. Disinfection and sterilization play an important role in the operation of the entire system of stainless steel reverse osmosis ultrapure water equipment. To ensure strict and high-standard effluent water quality, sterilization and disinfection is an important and indispensable link. Let me introduce the sterilization and disinfection methods of the stainless steel reverse osmosis ultrapure water equipment? 1. Pasteurization In the stainless steel reverse osmosis ultrapure water equipment system, the main function of pasteurization is: used in the purified water system Periodic disinfection of activated carbon and other pretreatment units, RO reverse osmosis, EDI modules, and purified water storage and distribution pipelines; also used for microbial suppression during normal operation of water for injection systems. 2. Ultraviolet sterilization Ultraviolet sterilization is a commonly used sterilization method for stainless steel reverse osmosis ultrapure water equipment. It mainly has the functions of sterilization, degradation of TOC and depletion of ozone. The effect of ultraviolet sterilization is determined by the intensity of ultraviolet rays, the spectrum of ultraviolet rays and the irradiation time. When the wavelength is 253.7mm, excellent sterilization effect can be obtained. Because the UV lamp can only inhibit the reproduction speed of microorganisms, cannot quickly and effectively reduce the load of microorganisms in the water, and can only kill some microorganisms in the system, it cannot replace the periodic disinfection or sterilization functions of pasteurization and ozone disinfection. 3. Ozone sterilization Compared with the ultraviolet sterilization and pasteurization described above, ozone sterilization uses oxidation to kill bacterial propagules, spores, viruses, and fungi, and it can also destroy botulinum. Ozone can effectively remove halides in water and degrade biofilms without residues. It is currently an excellent method for continuous removal of bacteria and viruses in purified water systems and high-purity water systems. The ozone sterilization method has become a commonly used method of disinfection of purified water at home and abroad. In addition, ozone can also oxidize and decompose pollutants in water, and has significant effects on smelling, decolorizing, sterilizing, removing phenol, cyanide, iron, manganese, and reducing COD and BOD in water treatment. The above is a section of the editor's introduction to the sterilization and disinfection methods of stainless steel reverse osmosis ultrapure water equipment. I hope it will be helpful to everyone. The sterilization and disinfection purifies the water quality and plays an important role in the system. We also need to understand which disinfection methods there are in the water system, which will help to purify the water quality.
