Odour Abatement

imagen recaj   Odor control in waste water treatment plants and pumping stations is already a priority in the integration with the neighborhood. Lately the energetic and economic optimization of deodorization has become very important.

   This article describes efficient solutions with very low operating costs for specific elements of plants, using small passive compact units, able to operate without fan, and loaded with selected impregnated activated alumina adsorbents. The results and capacity shown make this solution ideal in sludge silos, thickeners, septic tanks, sludge reservoirs and digesters, storm tanks and others, as opposed to the usual deodorization design criteria by a certain number of hourly renewals.

imagen jorgevicente   The objective of this paper is to describe and evaluate the project of odour impact reduction by means the design, erection and start up of a osmogenic barrier through a spray system of specific products, in waste mechanical and biological treatment plant.

   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 experience has been developed at the Helados Alacant Factory and its EDARi. The technologies studied were: Bioscrubber, Nanoparticles of Zerovalent Iron and Photoreactors.
