Task:

• Dimensioning and retrofitting the exhaust air treatment of the mechanical treatment stage of a sewage plant

Pollutants removed:

• Ammonia (NH3),
• Volatile organic compounds (VOC),
• Hydrogen sulphide (H2S),
• Odorous substances.

UGN® technology employed:

• 15 m³ of UgnCleanPellets® S 1.0 hybrid filtering material

Project description:

The exhaust air from the mechanical wastewater treatment is fed into a central exhaust air filter with an upstream exhaust air humidifier by way of an air extractor. As a part of this project, UGN checked and readjusted the air extractor, converted the biofilter into a hybrid filter (by installing UgnCleanPellets S1.0) before recommissioning and redimensioning the system.
On top of that, the plastic air extractor was repaired and the humidifier and the fans were serviced.
