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

le .

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.

Odour Sources in a Conventional Sewage Treatment

le .

sesion01 pagans01 Custom   Odour generation is an inherent side product of waste water storage and treatment. Encroachment of developments in the proximity of sewage treatment works increases the risk of adverse odour impact on receptors.

   Quantification of individual odorous processes helps operators understand which aspects of their works may be responsible and offers opportunities to find solutions to problems that may exist.

The first Interlaboratory Proficiency Test involving stack sampling took place the 27th to 29th of October in Kassel, Germany

ilc germany in ESA, odours   Last year, a total of 40 laboratories from 14 different countries participated in an Interlaboratory Comparison (ILC)  to check proficiency according to European standard EN 13725/2003. However this ILC did not study the influence of  “Sampling” on the overall uncertainty.  Taking an odour sample is another parameter to take into account in the estimation of the overall uncertainty of a lab, and the Hessian Agency for the Environment and Geology (HLUG) organized a regular test with over 15 labs for the very first time. From the 27th to the 28th of October,  the first ILC that considered not only analysis, but also stack sampling was carried out.

   Interlaboratory comparisons (ILCs) also called Proficiency Tests are organised to check the ability of laboratories to deliver accurate testing results to their customers.
