Task:

• Avoiding corrosion of structures and eliminating diffuse odour emissions

Pollutants removed:

• Hydrogen sulphide (H2S),
• Odorous substances.

UGN® technology employed:

• L-Jumbo hybrid filter module for exhaust air treatment
• 2 m³ of UgnCleanPellets® S 1.0 filtering material

Project description:

The pumping station is an underground structure with a free wastewater infeed of about 2500 m³ per day. Due to turbulence in the infeed flow, odorous substances such as hydrogen sulphide are released from the wastewater, causing odour-related nuisance and biogenic corrosion at the structure. The UGN module was installed to prevent odour-related nuisance. The exhaust air is extracted from the system by way of a fan, and purified. In doing this, diffuse emissions from the pumping station are largely eliminated.
