Current methods of odor control in accordance with Amendment No. 2 of CP 32.13330.2018

Summary

In connection with the increasing demands of the environmental health, the issue of eliminating unpleasant odors holds a specific place. This problem is especially relevant for wastewater facilities; accordingly, it is reflected in the new editions of sectorial regulations and reference books. The main recommendations of Code of Practice 32.13330.2018 regarding the measurement, control and elimination of odor from organized and unorganized odor sources at wastewater disposal and treatment facilities are highlighted. The practical experience of applying the technologies specified in the CP 32.13330.2018 is described.

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

Summary

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.

Control of deposit site malodors: «Wet Barrier» technology

Summary

The issue of malodors control is relevant for wastewater treatment facilities. Information is provided on the use of «Wet Barrier» technology to control malodor from large area sources, such as sludge beds, sludge lagoons, deposition sites and others. The «Wet Barrier» technology for neutralizing malodors has become widespread in Russia. The use of this technology is provided for by BAT 15b of «Wastewater treatment with the use of public wastewater disposal systems of communities, urban districts». Information and technical reference book of the best available technologies ITS-2019 and CP 32.13330.2018 «SNiP 2.04.03-85 Sewerage. External networks and structures» (with Amendments No. 1, 2). Novosibirsk Vodokanal monitors the effectiveness of the technology in order to select optimal operating modes using the olfactometry method in accordance with GOST R 58578-2019.
