Engineering aspects of arranging odor removal at the wastewater treatment facilities of Mosvodokanal JSC


The arrangement of odor removal at the wastewater treatment facilities is a technically challenging and expensive task. In the process of the implementation a number of problems arise that the technical staff of the treatment facilities has not previously run into. The experience of Mosvodokanal JSC in implementing the odor removal program at the wastewater treatment facilities in Moscow is discussed. Currently, as part of the comprehensive upgrade of the main treatment facilities – Kurianovskie, Liuberetskie, Zelenogradskie and Butovskie, as well as during the construction of new small and medium-sized wastewater treatment facilities in New Moscow, the necessary covering of open storage tanks is being carried out. The systems for collecting vent emissions from under the cover are equipped with modern air ventilation systems for removing malodorous substances. At present, the total background of emissions of malodorous substances on the premises of the treatment facilities has been reduced dozens of times providing for the elimination of odors over the nearby areas of the city. In 2021 it is planned to complete the entire set of measures to remove malodorous substances at the Kurianovskie and Liuberetskie wastewater treatment facilities of Mosvodokanal JSC.

Methods of odor control in the systems  of wastewater transportation and treatment


At present odor is considered as an environmental pollution factor that produces a negative impact on human being. In the urban environment one of the main odor releasing sources are the facilities for wastewater transportation and treatment. The advanced approaches to the odor regulation and control at the wastewater treatment facilities are considered. The basic requirements to the methods of odor control are formulated. A review of the most widely used methods – thermal, biological, chemical (including ozonation), sorption, photocatalytical, electrodischarge, direct photolysis, is presented. Practical use of these methods showed that none of them used separately provided for meeting the requirements set to malodor control in the systems of wastewater transportation and treatment; therefore combinations of different methods shall be used. Examples of industrial-scale approbations of the combined most dynamically developing photosorption-catalytical method are given.
