Sterilization effect of electrolyzed water

Electrolytic water is a "magic water" with a certain degree of acidity, alkalinity and redox property produced by electrolysis of water through a special device. According to their different acidity and alkalinity, they can be divided into four categories: slightly acidic, weakly alkaline and strongly acidic, strongly alkaline electrolytic water.

According to a lot of research results and the results of our research, strong alkaline electrolytic water has good washing effect (its washing principle is similar to alkaline washing solution), while strong acidic electrolytic water has broad-spectrum, efficient and fast sterilization effect, which has been widely used in food processing industry for disinfection and sterilization of equipment, ground and personnel, infectious disease control in farms, and medical equipment disinfection and cleaning in hospitals. In addition, the research on using strong acidic and alkaline electrolytic water to partially replace pesticides for crop pest control in Japan and Korea is also very impressive. In recent years, agricultural universities have conducted more in-depth research on the mechanism, effect and use of electrolytic water for sterilization, and many research results have been achieved.

The main body of electrolytic acidic water sterilization is the hypochlorite ion produced after electrolysis, but compared with ordinary sodium hypochlorite, electrolytic acidic water effective chloride ion concentration even if reduced to less than 1/10 of the sodium hypochlorite solution, still has a broad-spectrum sterilization function, compared with the common ozone sterilization method, with low production costs (operating costs are basically similar to tap water), no impregnation can be quickly sterilized and other advantages. After the use of electrolytic water is immediately deactivated by light and proteins that revert to ordinary water, so there is no residual and environmental pollution problems.

Experimental results show that electrolytic water with an effective chlorine ion concentration of 10 ppm can kill all RNA microorganisms within 10 seconds. The killing test on food poisoning bacteria and spoilage bacteria showed that 23 out of 28 colonies of the test were completely killed within 10 seconds of contact with electrolytic water, and 2 bacteria died after 1 minute of contact. The residual Bacillus, green mold and Penicillium after 30 minutes of immersion, only the green mold was not killed. Therefore, the use of electrolytic water sterilization in most cases, do not need a long time soak cleaning and rinse method can be used. In Japan, electrolytic water sterilization has been widely used in the food processing industry. Many factories use electrolytic water to clean and disinfect employees' fingers and work clothes, equipment, containers, piping floors, walls, etc. when implementing the HACCP sanitation management model. If the cleanliness of the object is too poor, the surface dirt should be removed first and the cleaning water and cleaning time should be increased as much as possible. For more organic adhesion or uneven surface to be cleaned, first wash with strong alkaline electrolytic water, then use strong acidic electrolytic water sterilization can significantly increase the sterilization effect. However, electrolytic water has a corrosive effect on the metal, so it is required to be cleaned using stainless steel (good in most food machinery using stainless steel manufacturing), and from the structure as far as possible to do spreading to prevent the accumulation of electrolytic water.
