Performance of a column bed device packed with specially fabricated Plaster of Paris (POP) pellets was evaluated for the removal of a potentially toxic Polycyclic Aromatic Hydrocarbon (PAH) Pyrene (Pyr). The effect of initial Pyr concentration, flow rate, and adsorbent dosage was investigated on Pyr adsorption characteristics of two types of pellets (uncoated and adsorbent coated). Maximum Bed capacity (Mb), percentage removal and equilibrium Pyr uptake were calculated and breakthrough curves were plotted. Data from column studies were fitted to three well-established column kinetic models; Thomas, Adams-Bohart, and Yoon-Nelson. The data were in good agreement with theoretical results. The study revealed the efficacy of newly designed pellets coated with thin layer of chitosan and alginic acid in the fixed bed column device for removal of Pyr from the water. Overall, the study provides a novel design of a column bed and baseline information for the efficient removal of PAH from the water.
