  ABSTRACT: With the stated advantages of finer adsorbent of high surface area, why then do manufacturers design unspecified active carbons of granular size even for the removal of medium size particles? This research attempts to provide one of such answers. A batch equilibrium adsorption study was carried out to assess the adsorption capacity and intensities of methyl red dye onto “Received” Granular Activated Carbon (GAC) and “formulated” Powdered Activated Carbon (PAC) .The equilibrium data obtained were modeled using the Langmuir and Freundlich Isotherms. The data fitted best with the Langmuir model which was predicted by the highest R2 value (0.981). The experiment carried out demonstrated that GAC had a higher adsorption efficiency range of 33.4% to 93.55% and a high adsorption capacity of 1.176 mg/g. Generally, the research ascertained the reason why the manufacturer supplied the chosen adsorbent as “granulated particulate” instead of “powdered” as formulated for the purpose of this research.
