Odour Abatement

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.

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.

Oxicrew   The purpose of this article is to evaluate the effectiveness of the ozone technology. In this case study, an ozone unit was inserted after a chemical scrubber. Odour samples were taken before the scrubbing, after the scrubber (and before the ozone unit), and after the whole set of abatement. Very high efficiencies were found.

   To this end, a test was carried out treating with ozone a part of the flow of a chimney in an animal by-products processing plant. The report of the VOCs and odours analysis laboratory confirmed the test success.
