OREANDA-NEWS. February 26, 2010. EuroChem has begun the complex process of fine-tuning new equipment for water disinfection at its subsidiary OJSC Nevinnomysskiy Azot in Nevinnomyssk, Stavropol region. The launch of the new RUR7mln system will take place in February and March 2010. The project involves changing out and modernizing old equipment for water disinfection in order for the company to comply with safety regulations.

The new water disinfection system involves the joint operation of new technologies to decrease the content of organo-chlorine compounds in drinking water and improve its taste.

The retrofit of the old chlorination system to modern Russian-made equipment for purifying the company’s drinking water will be made in the steam-water supply and communications shop at Nevinnomysskiy Azot. Some of the new equipment disinfects water using ultraviolet radiation (UVR) and electrochemical synthesis with AQUACHLOR-500, an oxidant solution.

The use of ultraviolet radiation UVD-18A by two water disinfection installations is based on physical, non-reagent water preparation processes. It means that with the help of this installation, microbiological measures of drinking water are aligned with regulatory requirements and norms for sanitation without the traditional application of liquid chlorine in the purification process.

The goal of the two other AQUACHLOR-500 installations is to provide additional disinfection after preliminary ultraviolet processing of the water. The oxidants – a blend of chlorine, ozone and chlorine dioxide – are derived through an electro-chemical process from a sodium chloride solution. The disinfection of drinking water by oxidant solutions is designed to preserve the effect of water disinfection as long as possible, and remove the possibility of malignant microorganisms and bacteria generation as it flows to consumers through the water supply system.
