AB  - Development of aerobic granules for the biological degradation of 
      2,4-dichlorophenol (2,4-DCP) in a sequencing batch reactor was reported. A key 
      strategy was involving the addition of glucose as a co-substrate and step 
      increase in influent 2,4-DCP concentration. After operation of 39d, stable 
      granules with a diameter range of 1-2mm and a clearly defined shape and 
      appearance were obtained. After granulation, the effluent 2,4-DCP and chemical 
      oxygen demand concentrations were 4.8mgl(-1) and 41mgl(-1), with high removal 
      efficiencies of 94% and 95%, respectively. Specific 2,4-DCP biodegradation rates 
      in the granules followed the Haldane model for substrate inhibition, and peaked 
      at 39.6mg2,4-DCPg(-1)VSS(-1)h(-1) at a 2,4-DCP concentration of 105mgl(-1). 
      Efficient degradation of 2,4-DCP by the aerobic granules suggests their potential 
      application in the treatment of industrial wastewater containing chlorophenols 
      and other inhibitory chemicals.
