The Difference Between Ozone Disinfection and Chlorine Dioxide Disinfection of Wastewater in Dental Clinics

There are more and more dental clinics and oral clinics. Although the amount of sewage produced is very small, such sewage contains many bacteria and viruses. It must be sterilized by special sewage treatment equipment before it can be discharged. Now there are two disinfection methods for sewage treatment on the market, one is ozone sterilization, and the other is adding chlorine dioxide. So what are the advantages of these two disinfection methods? Ozone sterilization: The sterilization mechanism of ozone is to destroy and oxidize the cell membrane, cytoplasm, enzyme system and nucleic acid of microorganisms, thereby rapidly inactivating bacteria and viruses. Ozone uses electrolyzed air as the raw material, and has the highest killing rate on pathogenic microorganisms, bacteria, viruses, etc. contained in the sewage of medical institutions. The equipment uses physical methods to treat sewage, without adding drugs, and there will be no phenomenon of excessive chlorine discharge, and no follow-up investment costs will be incurred. The whole set of equipment runs fully automatically, without personnel management and maintenance. Chlorine dioxide sterilization: A large number of experimental studies have shown that chlorine dioxide is a safe and non-toxic disinfectant without"San Zhi"effects (carcinogenic, teratogenic, mutagenic), and at the same time, it does not react with organic matter in the disinfection process to produce"Triple action"organic compounds or other toxic substances. However, due to the relatively strong oxidizing ability of chlorine dioxide, it should be avoided at high concentrations (>500ppm) use. When the concentration is lower than 500ppm, its impact on the human body can be ignored, and when it is below 100ppm, it will not have any impact on the human body, including physiological and biochemical effects. There is no sensitization effect on the skin. In fact, the conventional use concentration of chlorine dioxide is far lower than 500ppm, generally only around tens of ppm. Therefore, chlorine dioxide is a safe, non-toxic green disinfectant. The use of ozone sterilization does not require operating costs in the later stage, and it is more environmentally friendly and hygienic. Chlorine dioxide needs to be dosed regularly. Relatively speaking, it is more convenient to use ozone to sterilize. Sewage is often discharged in outpatient clinics, and if the sewage is discharged directly without treatment, it will not only pollute the environment, but may also contain bacteria, leading to the spread of bacteria and virus microorganisms in the sewage. The integrated design of the equipment occupies a small area; the sewage treated by the equipment meets the national discharge standards, which effectively reduces the risk of environmental pollution caused by the spread of bacteria and virus microorganisms in the sewage; energy is saved through the precise control of the microcomputer controller consumption.
