Can the water after ozone disinfection be drunk directly?

Recently, I have seen a water purifier that has ozone sterilization function on the market. Can the water after ozone sterilization be directly consumed?

Ozone (O3) is composed of three oxygen atoms and is a strong oxidant. It has the functions of instant disinfection and sterilization, and the sterilization rate can reach 99%.

   Ozone disinfection has the following characteristics

      (1) High-efficiency ozone disinfection does not require any other auxiliary materials and additives. When the disinfection is carried out, the ozone generating device generates a certain amount of ozone. In a relatively sealed environment, the diffusion is uniform, inclusive, and permeability is good, and the ultraviolet sterilization is overcome. The existing problem of disinfection dead angle achieves the purpose of omnidirectional, rapid and efficient disinfection. In addition, due to its broad spectrum of sterilization, it can kill bacterial propagules, spores, viruses, fungi and protozoal spores. Microorganisms can also destroy botulinum and toxins, rickettsia, etc., and also have a strong function of removing mold, cockroaches, odor and other odors.

      (2) High-grade ozone can be naturally decomposed into oxygen in the environment, which is the unique advantage of ozone as a disinfectant. Ozone is produced by using oxygen in the air as a raw material. (O) After 30 minutes, it is combined into molecular oxygen (O 2 ). There is no residual substance, which solves the problem of secondary pollution of the disinfectant when disinfecting. At the same time, it eliminates the need for re-cleaning after disinfection.

      (3) Convenience ozone sterilization equipment is generally installed indoors or in central air conditioning systems, air purification systems, or sterilization equipment (such as ozone disinfection cabinets, transfer windows, etc.). According to the concentration and time required for sterilization, Automatically set the timing control of ozone sterilization equipment. Ozone disinfection can be turned on and used every day. When formaldehyde, epoxy acetic acid and other chemicals are fumigated, it is difficult to operate regularly due to long disinfection time and inconvenient operation.

      (4) Economical Ozone disinfection method has great economic and social benefits compared with other methods through the application and operation of ozone disinfection and sterilization in pharmaceutical enterprises.

      As a good disinfection method, ozone has been applied on a large scale in many fields such as pharmaceutical companies, medical and health care places, food processing plants and residents' daily life. It is called “green disinfectant”.

 

The ozone-treated water is called “ozone water” and is oxidizing, but the nature of ozone is very active and unstable. It is converted into oxygen in water for a few minutes. Therefore, the ozone-treated water is left for 15 minutes before drinking. It is safe.

In addition, the ozone-containing water directly contacted by the human body can be drunk if the ozone concentration is generally not more than 0.2 mg/m3, and is harmless to the human body. When the water contains more than 1.5 ~ 2.0ppm of ozone, it is toxic to the human body and should not be drunk.

Therefore, if the water purifier has an ozone sterilization function, it can indeed have a particularly good sterilization function, but this ozone control amount is the key to the technology and is controlled within the standard of harmlessness of the human body.
