| Summary, etc. | This study was conducted to investigate the kinetics of Pb and As in an ACF system. An artificial suspension of Pb and As was used as the influent for the laboratory scale experiment. For each session of experiment one of the three parameters: initial concentration (C0), flowrate (Q) and operation time (t), were varied while the other two were kept constant. Average removal efficiency of Pb and As was found to be 100 and 13 percent respectively for initial concentrations below or equal to 10 ppm. Using arsenic contaminated groundwater samples ACF showed an average of 24.6 percent removal efficiency when two filters were used in series. At a flowrate of 40 mL/min and initial concentration of approximately 10 ppm, the breakthrough point for Pb was reached in approximately 4.25 hr. However for As the point was reached at 5 hr. Adsorption capacity of Pb in ACF is 0.5 mg/mg of ACF, whereas, for As it is only 0.18 mg/mg of ACF. The study concludes that performance of ACF for the removal of Pb and As is highly sensitive to changes in operational parameters C0 , t and Q. Correlation data shows final concentration of Pb (in ppm) increases with increase in C0(ppm), t (hr) and X (mg) (total amount of adsorbate removed) by factors of 0.66, 0.62 and 0.48 respectively. Final concentration of As (in ppm) increases with increase in C0 (ppm), t (hr) and X (mg) by factors of 0.95, 0.80 and 0.42 respectively. Removal efficiency of ACF decreases by the factor of 0.53 with increment of operation time by one hour for both Pb and As. Raw data shows increase in removal efficiency of As with increase in Q, and decrease in removal efficiency of Pb with increase in Q in ACF. Different models were proposed to explain the variation of final concentration of Pb or As with the variation of the above mentioned parameters. The types of models generated were linear regression models, non-linear two-dimensional models and non-linear threedimensional models. Most of the linear models gave above 60% fit of the experimental data, whereas non-linear models gave above 90% fit. Non-linear models best described the relationships of C with C0 and t. The developed three-dimensional models described the kinetics of Pb and As with high accuracy (Rsquare was 0.9010 and 0.9812 respectively). The study concludes that, although the ACF filter may be highly efficient for the removal of Pb from drinking water, it may not be practical to use it as a stand-alone system for the purification or As contaminated groundwater. |
