The experience of operating the systems for removing malodorous substances at the wastewater disposal facilities


To prevent the unpleasant odors spreading from the wastewater disposal system SUE «Vodokanal of St. Petersburg» is carrying out continuous studies and tests, and introduces various technologies, equipment and materials to reduce the concentration of malodorous substances entering the atmosphere through the ventilation system. Herewith, the main technologies used are as follows: adsorption, biofiltration, electrodischarge (plasma-catalytic) methods and the combined use of electrodischarge and sorption methods. As part of the work carried out over the past 10 years, an analysis of the operational and economic aspects was executed, as well as the effectiveness of the implemented technologies for the removal of malodorous substances at the facilities operated by the State Unitary Enterprise «Vodokanal of St. Petersburg» was studied. To select the most effective technologies and equipment, a scoring analysis method was developed.

Surface runoff treatment from urban territories and adjacent railway utility lines


Surface runoff has been one of the main pollutants of the environment alongside with domestic and industrial wastewater. Surface runoff constituting filtrate from railway bed is highly toxic and shall be subject to special decontamination before discharge into water bodies. The studies are aiming at the development and selection of the optimal method from the point of efficiency, cost effectiveness and ease of using the technology of surface runoff treatment from residential territories of Samara and adjacent railway. The problems of purification of surface runoff from railway bed and adjacent residential territories of Samara are considered through the example of discharge into the Depovskii gully. During the study samples of wastewater were taken and analyzed to estimate the composition of pollution. Basing on the analysis results several options of surface runoff treatment with the use of different technologies are considered. The improved process flow scheme that provides for 85–90% efficiency of surface runoff treatment is proposed provided its implementation is economically feasible. The given technology shall be implemented with its upgrade to complete purification.

Sorbent based on modified hydrolysis lignin for the purification
of wastewater from oil refineries


The results of studies of using SynergySorb® PS-1000 sorbent based on modified hydrolysis lignin for the purification of wastewater from large oil refineries are presented. Owing to the developed system of micro- and mesopores, the sorbent effectively absorbs light fractions of hydrocarbons, thus reducing the total content of oil products in wastewater and the intensity of odor near open treatment facilities. The total dynamic exchange capacity of the sorbent for oil products was 0.605 g/g while filtering wastewater from one of the largest Russian oil refineries. The average treatment efficiency before the breakthrough of oil products was 94%, the intensity of effluent odor as a result of tests was reduced from 5 to 2 points. Spent SynergySorb® PS-1000 sorbent belongs to the 4th hazard class (low hazard) in terms of toxicity and ecotoxicity.
