The odor challenge

Why pumping stations create short, intense odor peaks

Wastewater enters the well

Incoming flow varies with time of day, rain, upstream users and sewer conditions

Wastewater is temporarily retained

Longer residence time and low oxygen conditions can increase the potential for sulfide formation

Pumps start and stop

Pump cycles change the water level, airflow through ventilation and the amount of turbulence in the wet well

Odorous gases are released

H₂S and other volatile compounds can enter the exhaust air and create emission peaks and a strong odor perception

Conventional treatment

Traditional technologies struggle with peak loads and gas mixtures

When breakthrough occurs, community complaints rise and regulatory compliance is threatened. You need an active response, not a passive filter.

THE AIRSHIELD APPROACH

Air cleaning that responds to pollution loads

An electric process that actively adapts the system power based on the pollution load

Condensing airDesigned for humid conditions
Mixed compoundsA single system to treat H₂S, VOCs and other odors
Limited spaceA compact, plug-and-play unit
