| Popis: | This kinetic study simulates the characteristics of diazo dye (C.I. Reactive Red 141, RR 141) decolorization using an upflow-packed bed bio-reactor (immobilized cell system, ICS) with indigenous Aeromonas hydrophila entrapped onto the packing matrix, Porites coral. The kinetic theory of bio-reaction in ICS column is found to be the bio-reaction based on Langmuir adsorption isotherm. Our analyses upon two kinds of experimental data reveal that: (1) both ICS data have the first-order and the zero-order asymptotes, two features of reaction with Langmuir adsorption isotherm; (2) all ICS data have a common adsorption equilibrium constant; (3) both the viability of immobilized cells and the ultimate extent of bio-reaction are proportional to the amount of inlet nutrient source; (4) the former is independent of the flow rate of stream; however, the latter is inversely proportional to the flow rate of stream. |
