AB  - A predictive isotherm model was developed to evaluate the extent of 
      bioregeneration of granular activated carbon loaded with phenol and 
      2,4-dichlorophenol (2,4-DCP). Two basic substrates (116 mg/L of phenol and 100 
      g/L 2,4-DCP) as single solute were prepared. The mixture of them was provided to 
      bisolute system for assessing the competitive adsorption. The effect of 
      by-products, which were generated during biodegradation of substrate and measured 
      as COD, on bioregeneration in the bisolute was investigated. Freundlich 
      adsorption parameters (Kads and 1/n) of 2,4-DCP were obviously higher than those 
      of phenol in both single and bisolute. By-products in the bulk solution brought 
      an adverse effect on adsorption capacity of GAC in all cases. By taking into 
      account the by-product effect on adsorption, the Freundlich isotherms were used 
      to formulate a predictive model of bioregeneration. Simulated results showed good 
      consistency of observed results. Practical relevant of the proposed model for 
      assessing of bioregeneration in the wastewater treatment was discussed by 
      applying model to the BAC-SBR in the steady-state operation.
