Analysis and criteria of using degassing methods in wastewater disposal systems (a review)

Summary

An analysis of international and Russian scientific studies related to preventing anaerobic conditions in sewer networks by taking operational and construction measures was conducted. A list of alternative methods for the effective suppression and elimination of malodors from foul-smelling volatile pollutants (hydrogen sulfide, ammonia, phenol, formaldehyde, etc.) emitted from point sources such as wastewater treatment facilities, pumping stations, ventilation hoods of canals and sewers is presented. The aspects of effective blocking of gas formation processes and reduction of gas spreading in the gas sphere by various methods, including physical-chemical, construction, etc., are considered in order to prevent aggressive gases from escaping to the daylight surface.
