Microwave system to reduce emission of contaminat waste

Researchers from the Microwave Division (DIMAS) have presented a microwave system that helps several industrial sectors to reduce the emission of contaminant waste.

The equipment was exhibited at the annual event of the Telefónica Chair, which was held on 1st December 2011 at the Universidad Politécnica de Valencia. The Telefónica Chair promotes the development of innovative projects aimed at the environmental sustainability and social inclusion. In this event, interesting talks were given about “the sustainable energy model” and different research results sponsored by the chair were presented.

There are a good number of industrial processes which use materials repeatedly in consecutive series of production, undergoing a gradual degradation. After some uses, these materials have to be discarded and substituted. An example is the progressive degradation suffered by industrial oils at elevated temperatures. Another example takes place in the manufacturing of aluminium profiles since the successive immersions of profiles in caustic soda solutions causes a gradual degradation of the solution. When these materials reach a certain degradation level, they must be discarded generating highly contaminant wastes which have to be treated in a complex way.

The microwave system developed by DIMAS is able to monitor the materials state by real-time dielectric measurements. The sensor response depends directly on the material state and degradation level and allows extending as much as possible the materials’ life cycle before disposal. Therefore, the environmental impact of production processes is reduced.

The following video shows a description of the microwave system together with a brief demonstration of use.
