Photo Catalytic Degradation of Concentrated Effluent

Abstract

Many toxic harmful pollutants enter the water bodies, soil and atmosphere directly or indirectly. Industrial wastewater which may contain highly toxic/refractory compounds, needs special treatments before it can be recycled (or even dispose of).Some time these pollutants are not treated with conventional methods. For them we have to go for advance oxidation process. Photo catalytic methods offer some distinct advantage over conventional technologies, such as air stripping, vapor extraction, and carbon adsorption. In this process oxidation occurs through an attack by .OH, which has a rate constant billion times higher than normal oxidation rater constants. The treatment of wastewater using this method gives good results.

This project involves photo catalytic degradation of wastewater using titanium dioxide as catalyst. Titanium dioxide has some good advantage which gives the best treatment results for wastewater in combination with UV-light.
