Project title:

Reduction of nanoparticle emissions by the optimization of residual combustion gases filtering processes

No. 175/25.10.2011

 

Goal of the project is to reach effective ways to manipulate nanoparticle suspensions in fluid media using dielectrophoresis, in order to their retaining from flue gas and improving the filtration precesses. Nanoparticles are a major polluting factor, with impact on the environment and health. Massively generated in combustion processes they are highly toxic: once inhaled, penetrate, enter the blood, and can reach the brain, with irremediable damages. Therefore, combustion gases filtering become a major objective. The classical methods (mechanical, optical) provided poor results, o promising direction of research being dielectrophoresis (DEP): the movement of polarizable matter placed in a non-uniform electric field. The DEP force depends on the particles physical properties (size, electrical properties), fluidic medium, and of the applied field. By using DEP can manipulate nanoparticles suspended in fluidic media (air filtration, water purification) or to separate cancer cells from blood, bacteria, and viruses. The project intends to study the nanoparticles electrohydrodynamic: the movement in a fluid medium under the DEP, viscosity, gravitational forces, etc. The numerical simulations will provide the knowledge necessary for a device designed to nanoparticles manipulation and some experimental research regarding the filtering of combustion gases evacuated from a waste incinerator will do. Substantiation of a model of public environmental policy and strategies meant to reduce nanoparticles emissions in the city of Timi┼čoara will do finally.
