Treatability studies on bleach effluent of pulp and paper industry by ultraviolet/hydrogen peroxide process with titanium dioxide as catalyst
نویسنده
چکیده
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 Ultra violet / Hydrogen peroxide process was able to remove 52% and 59% 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.
