MartinezSoria   Emissions of volatile organic compounds (VOC) in several industrial sectors are regulated by increasingly restrictive policies, requiring the implementation of control treatments. In recent years, we have been working on the scaling of the biotrickling filter (VOCUSTM) for its industrial application, and there are several companies in Europe that already use this technology to control their emissions.

   This work compiles the results of the cases of implantation of this technology in various industrial sectors, with VOC of very different nature, from the very soluble ones such as the flexographic industry, to the cases of elimination of styrene emitted in the composite industry and mixtures of soluble and hydrophobic compounds typical of furniture or automobile coating industries.

Valdenebro   The RAMS-CALMET-CALPUFF modelling system has been used to simulate the odorous impacts from a paper-mill in an urban area located several kilometres away in a coastal mountainous area.

   Over the last years, episodes of citizens complaints due to malodours have been registered, with a potential origin in several pollution sources located inside and outside the city. A selection of episodes under anticyclonic conditions, with poor ventilation in general and continuous changes of stability and wind during the day, has been simulated.

lorenzo   This report exposes the results obtained during the operational years of two plants where Advanced Biofiltration System (BAP) were installed to treat the odour emissions created during the process or from the sewage waters derived from this process.

   In order to evaluate the operation of BAP systems, the results of dynamic olfactometry (UNE-EN 13725:2004) and of the concentration of hydrogen sulphide (H2S) were considered, since this latter compound significantly contributes to the overall odour impact in the analyzed case studies.
