Potential of biofiltration for VOCs emission control and safety aspects

Directive 99/13/EC on the emission of Volatile Organic Compounds (VOCs) is impacting on several industries in Italy, as well in other EU countries. Many small enterprises have to invest in new control systems and need to be helped to choose an appropriate and safe technology. As VOCs are highly flammable compounds, high concentrations in emission flows can pose a fire and explosion hazard if control systems are not properly designed and proper procedures are not implemented. Biofiltration may be considered as a suitable solution for VOC emissions control, as investment and operation costs are lower and performances are comparable with other abatement systems and comply with permit requirements. Furthermore, mild exercise conditions allow safer operations.
