Dynamic removal of Alizarin Red S (RAS) by activated carbon Norit GCA830 has been experimentally studied in fixed bed column. We can predicted the value of column parameters as a function of inlet solution dye concentration, flow rate and bed height. A static study has been first conducted, from which maximum adsorption capacity is defined; it’s of 385mg/g. Both Freundlich and Langmuir models were found to fit the sorption isotherm data well. For dynamic experimental study; series of column tests using activated carbon were performed to determine the breakthrough curves with varying the bed height, inlet solution dye concentration and flow rate. Adsorption capacity in fixed bed is defined from breakthrough curves is similar of that defined in static study. In addition adsorption capacity of fixed bed is correlated in function of operating conditions cited above. The kinetic model “Bed Depth Service Time” (BDST) is another method used to defined the adsorption capacity of AC in fixed bed in addition of other kinetic parameters such as constant kinetic, the thickness of mass transfer zone and the velocity of migration of adsorption zone. According to operating conditions the adsorption capacity is mostly depend of residence time.
