The odor emissions from environmental facilities (composting plants, EDARs, rendering…) are a frequent cause of nuisance in their surroundings which are given ever increasing attention. Therefore, stringent ambient air odor level requirements are being implemented worldwide which the conventional treatment technologies (such as scrubbers, conventional biofilters) are often unable to achieve.
In order to overcome these limitations, high capacity odor reduction technologies have been developed (such as Advanced Biofilters or Thermal Oxidation), which are already working in different real applications. In this work, the performance of 4 Advanced Biofilters treating COV and odor emissions has been evaluated.

Odour control is an increasing concern in WWTPs. Physical/chemical end-of-the-pipe technologies for odour abatement are relatively expensive and present high environmental impacts. Biotechnologies, on the other hand, have recently emerged as cost-effective and environmentally friendly alternatives but are still limited by their investment costs and land requirements. A more desirable approach to odour control is the prevention of odorant formation.
Galindo waste water treatment plant was designed in the 1980s on the plot of a dump in a highly industrialized area. The industrial conversion plan and urban development have remodeled the surrounding landscape, making it an urban established plant, causing conditions to which the plant could not offer solutions.
