... also possible to realize that the longer the portion of AC-Fe, the higher the adsorbent cost. Therefore, optimizing the AC-Fe portion in the column is one of the key factors for a feasible ... solute (arsenic anions) in the bed is decreased resulting to shorter contact between the feed and the adsorbent. In addition, the higher the flow rate, the smaller the film resistance, implying ... Adsorption column The appropriate LA/AC-Fe ratio It can be understood that the longer portion of AC-Fe in the column, the longer the breakthrough time, because according to the equilibrium and...
