The effect of ultraviolet disinfection of the Kur’ianovskie Wastewater Treatment Facilities’ effluent on the Moskva River biocenosis

Summary

Ultraviolet irradiation of urban wastewater is nowadays one of the safest and cost effective disinfection technologies. Ult­raviolet disinfection is a most efficient from the environmental point of view: no toxic by-products are formed in contrast to the traditional chlorination. Currently the biggest UV disinfection facilities have been operated in «Mosvodokanal» JSC: in September 2006 UV disinfection facilities with a capacity of 1 million m3/day were put into operation at the Liuberetskie Wastewater Treatment Facilities, and in December 2012 UV disinfection facilities with a capacity of 3 millions m3/day were put into operation at the Kur’ianovskie Wastewater Treatment Facilities. The results of analyzing phytoplankton, zooplankton and bacteriological communities in the receiving waters of the Kur’ianovskie Wastewater Treatment Facilities – the Moskva River before and after putting into operation the facilities for secondary effluent disinfection are presented in the paper. The comparison of biological characteristics of the water body with the river headwaters was carried out. Putting into operation the UV irradiation facilities provided for reducing bacteriological and virological water contamination. No changes in the plankton community structure were found. The river biocenosis keeps functioning inalterably. The use of UV disinfection technology ensures the epidemiological safety of the urban and rural population downstream the Moskva River.

The experience of using UV disinfection in the biggest European cities

Summary

The technology of drinking water disinfection by ultraviolet radiation has been widely used abroad. An example of the successful operation of UV-units is water treatment plants in Europe where various process flow schemes of UV disinfection have been implemented: as part of a multi-barrier scheme and as an independent method. The results of the introduction of UV technology at water treatment plants in Budapest (Hungary), Vienna (Austria), Berlin (Germany), Antwerp (Belgium) are presented. When preparing drinking water from surface sources it is recommended to use multi-barrier schemes including disinfection methods that ensure a prolonged effect. The effectiveness of UV disinfection in relation to viruses and protozoan cysts provides for reducing the dosage of chlorine-containing chemicals which inhibits the formation of chlororganic compounds. The decision to abandon chlorination while using UV-disinfection as an independent method should be substantiated considering the actual operating conditions of the water treatment facilities and water distribution networks.

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.

UV disinfection in water treatment: when, where, and who was the first?

Summary

A look back review of the origin of ultraviolet water disinfection technology in Russia is given. The paper describes the experience of SUE «Vodokanal of St. Petersburg» in the implementation of multi-barrier disinfection schemes in the preparation of drinking water, and the effect of using tested schemes on the introduction of UV technology in other cities of the country and abroad. Disinfection of water using ultraviolet irradiation that originated at the beginning of the last century, in St. Petersburg, Russia, as well, has now gained recognition around the world. The industrially proven multi-barrier disinfection technology using UV irradiation implemented at large-scale facilities in St. Petersburg, has found wide application and is dynamically developing in Russia and overseas. Unlike many other areas of science and technology, Russia has its own modern scientific and production school in UV technologies; the role of SUE «Vodokanal of St. Petersburg» and personally of Felix Vladimirovich Karmazinov in the formation of it being undeniable.
