Odour Control

Reduce odour discharges...

Hydrogen sulphide odours from pump stations are a common problem.  As a pump station fills with wastewater, air is displaced and along with it hydrogen sulphide and other noxious odours. A common hydrogen sulphide concentration in air discharged from a pump station is only 1ppm to 2ppm, but this is a major problem as the odour threshold for hydrogen sulphide is just 0.005ppm. 

For large pump stations, usual practice is to extract the odorous air from the pump station with a fan, and then treat the air with either a biological scrubber, a purpose designed carbon adsorption bed, or a soil bed filter.  However for smaller pump stations requiring only small air extraction rates, a far simpler solution is an Armatec Green Dome filter.
