Arsenic is known to be one of the most significant and severe inorganic pollutants in drinkable water globally. Many important techniques have been read for better results, such as ion-exchange, flocculation, precipitation, coagulation, adsorptions and other membrane technologies , when complying with the MCL (maximum contaminant level), Arsenic(V) around 10¼g / l in drinkable water) developed worldwide by the major World Health Organization, These available water treatment technologies are applicable; adsorption has proven to be a favorable and efficient technology for the removal of Arsenic from any form of water with dissimilar concentrations. In this analysis, Arsenic (As (V)) removal from water that studied by the packed bed column by modeling and simulation using iron ore adsorbent in the ASPEN ADSIM V11 software. The various effects on the efficiency of the adsorption column, such as bed height, feed-flow rate and the initial Arsenic concentrations of different operating parameters, were studied theoretically. Experiments were performed in specific cases to verify the results. Bed-depth greater then more Arsenic (v) are adsorbed and the Arsenic removal was achieved 100 % at a bed-height of 29.0 cm for simulation. The percentage of Arsenic removal, as well as the total adsorption of Arsenic increase with the decrease in flow rate, it is observed that when the bed height is increased the service time of adsorption bed also increases. The results showed that the design parameters such as adsorbent bed depth and column diameter, together with operating parameters such as Arsenic inlet concentration, have great effects on the overall column efficiency.
