   Many Environmental Treatment and Valorisation Plants (ITVAs), as wastewater treatment plants, composting plants, biomethanisation plants,... and other often generate odoriferous emissions which if not treated properly can actually cause serious nuisance to neighbors.

 

   Currently, there are advanced odour treatment technologies such as Advanced Biofiltration with Biological Advanced Filters (FBA) with inorganic support, Thermal Oxidation Systems and others (such as additional high dispersion systems, the Non-Thermal Plasma oxidation systems, ...) that allow a very efficient way to reduce the odor impact of an activity on the environment. Given the specific scope of each of these technologies its applicability is deduced after a detailed study of relevant cases that the emissions main characteristics (detailed composition,..) and other technical aspects of each technology.

   This paper will show the results of three real cases in which the application of these advanced treatment systems has reduced very significantly the odor impact of three different processes: a MSW composting plant, a bio-digestion of MSW and finally a rendering plant. Among other things it will show the efficiency of deodorization and the characteristics of each of these technologies and a comparison of the benefits of these technologies against deodorization usually installed. The study of these cases will show that the problems of odor impact, even the most complex, can be perfectly solved through the application of advanced technologies, and in some cases, can have overall costs throughout its operational life even lower than other technologies that offer a lower technological profile.

Dynamic Olfactometry and GC–TOFMS to Monitor the Efficiency of an Industrial Biofilter

mariadelcarmengutierrez 3   Biofiltration is the most widely used technique for eliminating odours in waste treatment plants (WTP). Volatile organic compounds (VOCs) are among the odorous compounds emitted by WTP, and serve as variables to measure odour emissions depending on the type of aeration process used.

   In this work, the performance and efficiency of an industrial-scale biofilter was assessed where composting was the main source of VOCs and odour emissions.

Selection criteria for odour abatement technologies have been traditionally economic and based on the flow rate to be treated, odour concentration (or of a certain surrogate such as H2S) and removal efficiency. However, nowadays social and environmental aspects are starting to gain importance.

Odour abatement systems are designed to operate over long periods of time (20-30 years) and under dynamic scenarios and conditions. Therefore, an economic analysis of sensitivity of the operating costs towards different design and operational parameters is crucial.

Odour Impact and Odour emission characterization by means of olfactometry and physicochemical analysis techniques

When addressing the resolution of odour problems it is important to characterize as detailed as possible the involved emissions or affected ambient air, not just from the sometimes limited point of view of olfactometric techniques

   When addressing the resolution of odour problems it is important to characterize as detailed as possible the involved emissions or affected ambient air, not just from the sometimes limited point of view of olfactometric techniques, but also using physico-chemical analysis techniques, in order to identify the candidate sources of certain odoriferous episodes and/or to select the most appropriate treatment systems in each case or optimize their functioning and performance (note, in this regard, that such systems do not interact with a sensation such as odour but rather on specific odoriferous compounds)

   In this paper we present results from the application of a combination of olfactometric techniques (both in emission and immission) and chemical analysis covering a wide spectrum of odoriferous compounds in order to obtain a complete characterization of the odorous emissions from various environmental treatment facilities (Industrial Waste Treatment Plants, Ecoparks, ...) and their projection and impact on the ambient air surrounding the plants. The strategies to be applied include active or passive sampling grids, as well as advanced statistical treatment of data, the application of emissor-receptor models, ... The study techniques used in this work were both sensory (dynamic olfactometry and field olfactometry) and chemical speciation, including captation of odoriferous compounds (by means of different techniques) and the speciated analysis of both VOC and other compounds of odoriferous significance (H2S, NH3, ...) by HRGC-MS, UV-Vis spectrophotometry, potentiometry, etc.
