Abstract:

Emission of pollutants from area sources is still difficult to measure. The approach based on flux chamber that allows the isolation of a part of the source is retained, in this study, to follow emitted pollutants, their concentration and their odor. Two dynamic chambers (preferred to static chambers) are developed to simulate external wind and are both tested into a wind tunnel for laboratory development and on real sites. This tunnel (9 m long) contains an area source (surface of 0.75 m²) where synthetic solutions or real effluent (industrial wastewater) can be introduced. Two types (I and II) of chambers (tangential and modular respectively) are tested to measure odor flow emitted by liquid sources. These devices simulate external conditions for low wind velocities and then emission measurements corresponding to these conditions can be carried out. Laboratory studies and applications on industrial sites are given for both types of chambers.
