continues and patch adsorption study in a fixed-bed column was carried out by using
fired clay pot as an adsorbent for the removal of methylene blue (MB) from aqueous
solution.The effect of flow rate, influent MB concentration and bed depth on the adsorption
characteristics of adsorbent was investigated at pH 7. Five kinetic models Thomas, Yoon–
Nelson and Clark were applied to experimental data to predict the breakthrough curves using
nonlinear regression and to determine the characteristic parameters of the column that are
useful for process design, while a bed-depth service time (BDST) model was used to express
the effect of bed depth on breakthrough curves and to predict the time needed for breakthrough
at other conditions. The Yoon –Nelson and Clark models were found suitable for the
description of whole breakthrough curve. The BDST model was successfully applied to analyze
the column performance and to evaluate the model parameter. The empty bed residence time
model (EBRT) has been used to correlate the fixed bed pilot plant experimental results and also
it was found that the adsorbent exhaustion rate decreased with increasing EBRT. Error analysis
was carried out to test the adequacy and accuracy of the model equations.
