A process for the removal of coffee color from wastewater
A simple and efficient process has been developed and is described for the removal of coffee color from wastewater by carbon adsorption. The quantity of coffee color adsorbed by the carbon was strongly pH-dependent, being greater between pH 2 and 4. The contact time required to reach maximum adsorption was 60 min. The adsorption efficiency did not increase appreciably when the temperature was elevated. Under optimum operating conditions, this carbon adsorption process reduced the color concentration by 98. Studies have shown the adsorption of coffee color on activated carbon to be of the empirical Freundlich type
