Development of highly efficient thecnologies for odour treatment in industrial processes and wastewater treatment.

Most industries in the food sector generate strong odors in their processes and their wastewater treatments. This fact becomes a real problem (strong environmental impact on surrounding areas) 

It has been detected that most of the time; the real problems of smell are caused by the gas evolution from the mass of wastewater. A characteristic odor is that very small amounts of certain compounds (mainly organic) can produce high levels of odor.


On the state of the art, there are no technologies able to get a very high efficiency in the odor removal and at the same time, odor has a very subjective character so it is no easy to get a good solution to solve this problem.


The main objective of this project is to develop odor treatment techniques which provide more efficient and viable solutions than conventional treatments.


This project faces to several technological challenges

Determination of the most appropriate combination of technology for the removal of over 80% of odors produced during an industrial process and a water industrial treatment.

Use of a filler material currently targeted water filtration as filler material for air biofiltration process. 

Incorporation of nanoparticles in odor treatment processes for more efficient removal of the causative agents. 

Determination of the environmental impact of different deodorization processes, calculation of carbon footprint.
