COLOR REMOVAL FROM A DYESTUFF INDUSTRY EFFLUENT USING ACTIVATED CARBON

The objective of the present study is to identify the best commercially available activated carbon adsorbents to remove the colour of dye of the effluent (waste) water from dye using and dye manufacturing industry. The effect of different types of dyes, particle diameter of the absorbent, intial dye concentration, carbon loading, pH of the effluent water and temperature on best available adsorbent is evaluated. Adsorption isotherms are developed for different dyes and represented by Freundlich isotherm which can be used for the design of waste water treatment plants.
