Oxidant gas

According to the certificate of the National Sanitation Foundation USA (NSF), the oxidant gas consists of approximately 70% chlorine gas and 30% - chlorine dioxide and active oxygen. This mixture of gases is soluble in water and has a synergy in the decontamination process, which gives grounds to call oxidative gas the highly efficient water disinfection method able to replace completely the traditional and generally known in practice of the centralized, noncentralized drinking, service water supply and drainage system.

The advantages of oxidant gas water treatment:

1) The effectiveness of disinfection is significantly greater than in the processing of chlorine or sodium hypochlorite. It can be compared with the efficiency of ozonation, but everyone knows that ozone is the strongest oxidizer. Oxidative gas is effective against viruses and spores, pathogens agents such as dysentery, cholera, typhoid fever, salmonellosis, hepatitis and shistosomiazy etc. High efficiency can be observed in different physical and chemical states of water.

2) Treated drinking water is odorless and has a bluish tint, which can be provided only by ozonation.

3) The decontamination is carried out in accordance with the requirements of water and sanitary legislation of Ukraine - GOST 2874-82 "Drinking Water. Hygienic Requirements and Monitoring" and DSanPiN 136/1940 "Drinking water. Hygienic requirements and water quality of centralized water supply."

4) The monitoring of the disinfection process, based on the determination of residual chlorine as well as chlorination.

5) There aftereffect is longer than the chlorine processing or sodium hypochlorite, which is absent in the ozonation.

6) The formation of toxic and carcinogenic organ-chlorine compounds, including bromine, are significantly reduced in the water, and prevents the ability of water to form biofilms on the walls of pipelines. Such properties are absent in chlorine, sodium hypochlorite and ozone.

7) There is no aggressivity of water observed, which can be present in chlorination with sodium hypochlorite.

8) Less sulfur dioxide, or other agent is required to remove residual chlorine from water than in chlorine or sodium hypochlorite processing.

9) OXI-assembly is simple, cheap and safe in operation:

- Only water and salt is needed for their operation, and there is no need in use of toxic agents. Unlike the plants for ozone, chlorine dioxide, sodium hypochlorite production, where toxic acids or other chemicals are needed during the operation, which reduces the lifetime of electrodes and other communications or complicates safety and ease of equipment maintenance;

- It has a vacuum method of oxidant gas introduction to the treated water, which prevents gas leakage and provides necessary degree of security installations;

- It produces the reagent in required amount at any given time for water treatment and can be instantly switched on and off, which exclude the need for storage and transportation of hazardous substances;

- The productivity of OXI units can be easily increased by replacement more powerful or by their parallel inclusion.
