UV-disinfection stations in Kronstadt

In connection with constantly increasing requirements to the quality of refinement and disinfection of drinking water, the problem of creating modern systems for water refinement becomes more and more important. Kronstadt s water-supply systems in 2006 are going to introduce a new ultraviolet technology of water refinement.

The UV-stations are intended for disinfection of waters, that are taken from open sources - in case of Kronstadt it is the Neva River - and they help to improve the disinfection against chlorination-resistant microorganisms.

UV-stations are made of materials that are in conformity with sanitary and fire-prevention regulations, which are in force on the territory of Russian Federation. The stations use lamps with the wave-length of 250 nano-meters, which exclude formation of ozone. The construction of UV-stations does not allow the ultraviolet to exceed the bounds of the stations and provides safe conditions of work for the personnel.

The ultraviolet method of disinfection is characterized by:

• high efficiency of disinfection (including disinfection against chlorination-resistant microorganisms, such as viruses)
• complete absence of by-products that can be dangerous for living organisms
• a higher technical and economic showings than reagent disinfection
• a higher safety rate (storing of dangerous reagents is not needed).
  

The building of UV-stations in Kronstadt is aimed at environmental protection, since the process of chlorination is connected with agglomeration of halogenated carbohydrates in water, which is considered extremely dangerous.

High efficiency of UV-disinfection is proved by the experience of exploitation of such equipment in Saint-Petersburg.
