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

Summary

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.
