COLOR REMOVAL FROM A DYESTUFF INDUSTRY EFFLUENT USING ACTIVATED CARBON

The objective of the present study is to identify the best commerciall y available activated carbon adsorbents to remove the colour of dye of the effluent (waste) water from dye using and dye manufacturing indus try. The effect of different types of dyes, particle diameter of the a bsorbent, intial dye concentration, carbon loading, pH of the effluent water and temperature on best available adsorbent is evaluated. Adsor ption isotherms are developed for different dyes and represented by Fr eundlich isotherm which can be used for the design of waste water trea tment plants.
