| dc.description.abstract | Water contamination problems become a vital concern particularly dye pollution which is destroying the nature and human health. Therefore, this research study was carried out to discover the usage of activated carbon (CSAC) which is prepared from the coconut shell using microwave as an adsorbent for the adsorption of Methylene Blue (MB) and Methyl Red (MR) to reduce the dye pollution. Dynamic fixed bed adsorption study was conducted to find out the optimum conditions for the adsorption process to be carried out using few different parameters which are initial dye concentration (10-40 ppm), inlet flowrate of dye solution (4-10 ml/min) and bed height of adsorbent (2-4 cm). It was concluded that the breakthrough time was faster when the initial dye concentration and inlet flowrate is higher and the bed height is shorter. Besides that, column dynamics analysis was also performed using Thomas, MDR, Adams-Bohart and BDST model. It was analysed that Thomas and MDR analysis model fitted well to the experimental adsorption data as compared to Adams-Bohart and BDST analysis model. Finally, the scale up adsorption column study was conducted to predict the mass transfer zone and concentration profile in the bed. It was found out that the used up bed height (HB) decreases as the initial dye concentration and flowrate increases but the used up bed height (HB) increases as the bed height of the adsorbent increases. | en_US |
