Abstract

   The objective of this paper is to describe how the application of Osmogenic barrier by pulverization of specific products is an efficient system in odour reduction. The efficacy of the process has been evaluated by electronic nose technology.

   These products have hydrophobic groups, which have long hydrocarbons chains. This structure allows the formation of big molecular aggregates named micelles. This micelles prevent than malodorous molecules (osmogenic molecules) can be detected by the human sense and despite they are still present in the air, they don’t smell anymore.

   The assessment was performed in a landfill during 20 days, and 2 electronic noses, where used to evaluate the results. One device was placed at landfill boundary and the other at receptor located at 1,4 km. Those electronic noses were used when the osmogenic barrier was working and also when as inactive.

   Results showed a reduction in odour detection frequencies after application of the neutralization plant through osmogenic barrier, both at the landfill boundary and also at the receptor located at 1.4 km from the plant.
