AB  - A kinetic model incorporating adsorption, desorption and biodegradation processes 
      was developed to describe the bioregeneration of granular activated carbon (GAC) 
      loaded with 4-chlorophenol (4-CP) and 2,4-dichlorophenol (2,4-DCP), respectively, 
      in simultaneous adsorption and biodegradation processes. The model was 
      numerically solved and the results showed that the kinetic model was well-fitted 
      (R(2)>0.83) to the experimental data at different GAC dosages and at various 
      initial 4-CP and 2,4-DCP concentrations. The rate of bioregeneration in 
      simultaneous adsorption and biodegradation processes was influenced by the ratio 
      of initial chlorophenol concentration to GAC dosage. Enhancement in the rate of 
      bioregeneration was achieved by using the lowest ratio under either one of the 
      following experimental conditions: (1) increasing initial chlorophenol 
      concentration at constant GAC dosage and (2) increasing GAC dosage at constant 
      initial chlorophenol concentration. It was found that the rate enhancement was 
      more pronounced under the second experimental condition.
