The contribution ofSUE «Vodokanal of St. Petersburg»to Russia fulfilling the international commitments on theBaltic Marine Environment Protection


To meet the recommendations of the Helsinki Commission on the Baltic Marine Environment Protection the experts of SUE «Vodokanal of St. Petersburg» developed a 5–7 years rehabilitation program for the Ladoga and Onega Lakes basins. The program envisages construction of new or upgrade of the existing municipal and community wastewater treatment facilities; enhanced removal of toxic substances from wastewater at the industrial facilities; efficient processing of livestock and poultry farm wastes with the utilization of their useful properties and energy potential. The progress in implementing measures on abatement of discharging raw wastewater into the Gulf of Finland, upgrade and reconstruction of the wastewater treatment facilities, wastewater treatment efficiency improvement, particularly in relation to the technologies developed by the Universities of Cape Town (UCT) and Johannesburg (JHB) with the use of membrane aerators, mixers, nitrate recycling, and also to the European technology of chemical phosphorus precipitation is described. The dynamics of reducing nutrient loading on the St. Petersburg water bodies is presented. The positive effect of putting into operation the Main tunnel sewer has been achieved. The program of the municipal sewer rehabilitation has been developed and is now underway. The results of activities related to waste and toxic substances removal are presented. The works carried out will contribute to the prevention of the Gulf of Finland eutrophication.

Measures on preventing malodors release at the facilities
of SUE «Vodokanal of St. Petersburg»


SUE «Vodokanal of St. Petersburg» has been introducing and testing different equipment for gas purification with the aim of preventing malodors release at the wastewater facilities. The experience of applying gas purification technologies at these facilities is analyzed. It was determined that the specified features of STOPKR sorption-plasma-catalytic gas purification unit and OPVS biological air oxidizing unit are efficiently used at the sewage pumping stations. The economic inexpedience of using STOPKR method at input concentrations of toxic substances higher than 1 g/m3 is a disadvantage. Testing OPVS filter in sewers showed positive results. The disadvantages of OPVS filter are in clogging of filter elements during operation as well as difficulties in processing multicomponent gas mixtures and mixtures of variable composition because of the specificity of the resulting microbial strains. The results of pilot testing TSUF-2000-400-I gas purification system showed the absence of malodors around sewer wells and convenient operation of the unit. The use of different filters including GreenKomplekt carbon filter-based units did not give any meaningful results. To control odor at the wastewater sludge landfills fine spraying of deodorant solution along the periphery of the landfill was suggested. At the sludge incineration plants exhaust gases pass three-stage purification with the use of electrostatic precipitation. At the wastewater treatment facilities the construction of either entire process flow or partially closed system was suggested. The prospects if introducing various technical and technological methods at each of the wastewater facilities are determined.
