An improved process for decolourisation of agro-industry effluents to produce colourless effluent

This invention relates to an improved process for decolourisation of treated agro-industry effluents to produce colorless effluent. It relates to a catalytic process which increases the adsorption capacity for colouring matter from treated agro-industry effluent by activated charcoal. The process of the present invention thus aims at bringing about cost effectiveness in the tertiary treatment of distillery effluent or spent wash. By using cheap oxidation catalysts in ppm levels (which will not add to the cost of carbon powder) the adsorption capacity of the activated charcoal with respect to colouring matter has been enhanced in the present invention.
