Controlling malodorous emissions of wastewater treatment facilities

Summary

Wastewater treatment facilities feature malodorous emissions into the atmosphere that result from the process of wastewater treatment and contain mercaptans, hydrogen sulfide, ammonia, amines etc. The preventive measures against negative impact of malodorous emissions on the urban development include two stages: collection of the polluted emissions and their subsequent purification. Preventing emissions into the atmosphere and collecting gases are carried out by installing covers on the aeration facilities. The advanced and technically perfect method of air purification is used in «Iatagan» gas converters. The principle of «Iatagan» units operation is based on the combined effect of bulk barrier-streamer discharge and ozone on the molecules of hazardous and malodorous gases. The use of «Iatagan» gas converters is the best solution of the air purification problem at the wastewater treatment facilities.
