How to sterilize and disinfect the pure water production process?

Recently, the General Administration of Quality Supervision, Inspection and Quarantine announced on the official website the results of quality supervision and inspection of bottled water products. The quality of 18 drinking water products was closed to the black list, involving the total number of colonies, coliforms, mold, yeast, and bromic acid. Salt, conductivity, limit indicators ( 锶 content ) , free chlorine and many other items. Among them, Harbin medicine "pure medium pure" weak alkaline drinking water, "Jingyou" Ordos natural desert water was detected as a potential carcinogen bromate exceeded. (September 1, "Beijing News")

This incident has once again triggered the crisis of trust in food safety for the public. After all, this is used directly for the public to drink.

It is understood that pure water is produced by tap water through a certain production process, and is not restricted by resources. Therefore, the most bottled water that the people in the city drink is pure water. It can be seen that the quality of pure water has a close relationship with the lives of ordinary people.

Judging from the detection of pure water in recent years, the quality problem of bottled purified water is mainly concentrated on the microbial exceeding the standard. This is because in the process of pure water production, all links may contaminate microorganisms. Once contaminated by a small number of microorganisms, it may exceed the standard and even flocculation. Therefore, controlling microbial contamination is a very important task for production companies.

It has been reported that pure water is sourced from the water source-filtration-purification treatment-ozone mixed disinfection-filling-inspection. The water treatment terminal filter and the filling worker's hand are the key pollution links of microorganisms in the production process of bottled water. .

In addition, some manufacturers have imperfect equipment or do not directly fill the purified water after ozone mixing and disinfection, but wait for a certain period of time after filling through the water storage tank. At this time, the water is filled for 0.5 to 2 hours before being filled into the bottle . Ozone has passed about 2 to 8 years of decline, and the concentration of ozone in the water has dropped significantly. Even if the treated water itself is sterile, it cannot kill the residual bacteria brought back by the air in the package or the filling room when filling the bottle, and it also causes microbial contamination.

Therefore, the disinfection of bottles and lids and filling rooms has become the key to eliminating microbial contamination. How to ensure the disinfection work of the workshop when there are personnel working? NICOLER dynamic sterilization technology provides a solution to this problem. NICOLER sterilization technology is a dynamic disinfection device that uses signal oscillation to generate a large amount of plasma, killing bacteria in the air, metabolites in the human body, secondary pollutants in the system, etc., so that the controlled environment remains "Aseptic and dust-free" standard, and can continue to sterilize continuously in the case of some people, without any harm to the human body.

Measures to control microbial contamination of pure water should be comprehensive, and should not overemphasize one aspect, but neglect other aspects. Therefore, in addition to disinfecting the bottle, lid and filling room, it is necessary to strengthen the water source and packaging materials. And product testing, regular cleaning and disinfection of pipelines, containers and filters, etc., to improve the hygiene awareness of production personnel, and strengthen the training and learning of food hygiene knowledge.
