Abstract

The treatment of bleach effluent from pulp and paper Industry for COD, colour and AOX removal was investigated using Ultra violet/Hydrogen peroxide process photocatalysed by Titanium dioxide. The Ultra violet / Titanium dioxide process was able to remove 48% and 37% of COD and colour. The combined process of Ultra violet/Hydrogen peroxide process photocatalysed by Titanium dioxide was found to be more effective in the removal of COD and organics compared with the individual processes at a pH of 7. The combined process of Ultra violet/Hydrogen peroxide process photocatalysed by Titanium dioxide showed the COD colour and AOX removal efficiency of 76%, 78% and 45% respectively.
