Eternal engine of progress

Summary

The quality of water supply and wastewater disposal services over the first twenty years of the 21st century has brought SUE «Vodokanal of St. Petersburg» to a new level of development owing to the introduction of innovative technologies in water supply and wastewater disposal systems. The use of technologies, such as two-stage disinfection of drinking water, odor control of landfills, geotubing, the use of Flottweg centrifuges, powdered one-component flocculant, powdered activated carbon, the introduction of a precipitation measurement system, were carried out with the active participation of Fedor Ivanovich Lobanov, Assistant to the General Director of SUE «Vodokanal of St. Petersburg» on dealing with industries, who turned 80 in November 2021.

Prospects of surface runoff disposal and treatment in St. Petersburg

Summary

St. Petersrburg is the biggest megacity on the Baltic Sea, with well-developed industrial and transportation infrastructure. The scale of the city determines the level of the responsibility for the Baltic Sea state before the international community – participants in the Helsinki Convention. By the present moment a list of activities has been developed that includes rearranging direct outfalls and eliminating direct discharges of raw sewage into the water bodies; the process solutions on combined and domestic wastewater treatment to the required effluent quality standards have been studied in detail. The system of accounting the level of precipitation and calcula­ting the amount of surface runoff on the basis of this data is described. The information on the automated network of accounting the atmospheric precipitation and on the automated system to control this network is presented. The method of calculating surface runoff amount has been updated; the sanitation areas are being specified according to the digital territory plan. The studies of the surface runoff seasonal quality fluctuations are carried out; the classification of the territories according to the pollution type has been introduced. The surface runoff treatment facilities with the use of different process flow schemes are described.
