The Average particle size, Bulk density, Ash content, Moisture content and pH of the GAC were determined according to the methods described by Akpapunam and Markakis, (1981) and Metcalf and Eddy (2003). The water parameters were analyzed according to WHO/EC combined standards. The Scanning Electron Microscopy (SEM) was used to focus beam of high-energy electrons to generate a variety of signals at the surface of the solid specimens (GAC) and an image reader “image j” was then used to read the pore space and surface area. The fixed bed adsorption experiment was set-up with three rectangular bed filters having height, breadth, length and thickness of 0.16m, 0.18m, 0.18m and 4mm respectively. Ten liter gallon was used as reservoir for raw water samples collected at different points on the stream. The valves were opened slowly such that the feed samples were allowed to flow from the reservoir into the top open of the filter beds by gravity.
