Modern trends and peculiarities of UV disinfection usage in water treatment

Summary

A brief review of the amendments to SanPiN 1.2.3685-21 in terms of microbiological indicators and concentrations of substances associated with chemical disinfection in water treatment is given. The trends laid down in the new regulatory documents involve the use of the most effective process solutions in the field of water disinfection. A fundamental approach to the arrangement of multibarrier schemes for water disinfection, including the use of ultraviolet irradiation, is described. Examples of the water treatment facilities put into operation in large cities of Russia and overseas using the multibarrier principle of water disinfection using UV irradiation are given. The positive experience of upgrading water disinfection systems in drinking water supply systems of the cities in the Russian Federation and overseas, as well as the global trends and practice acknowledge the possibility of using UV irradiation as the most reliable and safe advanced disinfection technology.
