measuring odours and odour control

Reading time:

Respect for the surrounding environment means that the odorous gas emissions from our urban or industrial wastewater treatment plants must be subject to systematic control. Accordingly, these gases must be captured at the source and, therefore, the areas emitting these gases must be covered over but also ventilated in order to provide operators with an acceptable working area and to route these gases to an odour control facility.

However, before examining odour control, we have to quantify the odours emitted, identify the areas to be covered over, establish acceptable levels in the environment and in working areas. This sub-chapter examines these problems.

Finally, it should be noted that by examining these problems, we also resolve or improve other neighbourhood problems at the same time: noise levels and even the appearance of the plant (see section boiler water).
