Project: Application of photocatalytic processes for the degradation of industrial effluent : Study of the possibility of coupling to other conventional devices

Abstract:
The water pollution by industrial waste is indisputable and present risks for environment and health. They exist many of water treatment processes: flocculation, precipitation, adsorption, biodegradation, photocatalysis, etc. The ideal treatment, if it exists, will be the one which consumes less products, less energy and which not reject anything harmful to the environment.
The Photocatalysis is used to degrade the bio-refractories or toxic compounds using the hydroxyl radicals. It has many advantages: not requiring co-products, requiring little energy and minimize the secondary waste. The photocatalysis is an advanced oxidation process that allows complete decomposition of pollutant This advanced oxidation techniques, exploiting solar energy appear to be a promising way to the water treatment.
The main idea of this project is the development of photocatalytic reactor and use of solar energy as renewable source of energy combined with the semiconductors and other treatment processes to enhance the performance of the process. This combination causes a synergy that should increase the degradation rates of aqueous effluents.

Objectives:

  • Move from the catalysis as a chemical process to catalysis as a complete process of depollution.
  • Coupling the photocatalysis with other processes ;
  • Reach the complying with reject standards ;
  • Use of solar power as a source of renewable energy for water treatment ;
  • Increase the quality of the depolluted water ;
  • Advanced wastewater processing ;
  • Conception of photocalytic reactors ;
