3. Notion of treatment channel
The emission to be treated should be considered as a complex, more or less diluted mixture of aerosol particles and molecules with very different physico-chemical and biological properties.
For example, wet air emissions can contain dust, grease, heavy metals and VOCs. In such cases, it is advisable to set up not just a single treatment, but a process comprising both pre- and post-treatment. This concept is identical to that used to design and build water purification plants or wastewater treatment plants. In all cases, this succession of unitary operations must enable the system to be optimized to produce emissions in line with current discharge standards (an overview of current legislation is given in the For more information
