Biotrickling filter as technology for the control of industrial emissions of VOC: study of case viability

on .

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.

Advanced Treatment Systems for Odour Removal: success cases for industrial facilities

on .

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.

Proteins and free aminoacids from microalgae suitable for gas depuration

on .

Callejo   The use of microalgae in integrated gas purification processes has taken a special interest in recent years, mainly due to its ability to capture CO2. These applications involve the generation of biomass that can be used to obtain bioproducts and/or bioenergy.

   However, the development of these processes requires an improvement in the cell rupture and biocompounds extraction methods. The aim of this study was to evaluate a method for obtaining proteins and free amino acids (FAN) from Chlorella vulgaris.
