TI  - AC/O3-BAC processes for removing refractory and hazardous pollutants in raw 
      water.
PG  - 129-33
AB  - Granular activated carbon (AC)/O(3)-biological activated carbon (BAC) process was 
      employed to treat raw water and compared to O(3)-BAC process in its optimum 
      parameters (3 mg/L ozone dosage with 15 min oxidation time and 15 min empty bed 
      contact time in BAC). The results showed that the presence of AC improved ozone 
      utilization and biodegradability of the effluent. For dissolved organic carbon 
      (DOC) removal, AC/O(3)-BAC was more efficient than O(3)-BAC and its synergetic 
      effect could be noticed. It was showed that small molecules with molecular weight 
      (MW)<3 kDa predominated in the raw water accounting for more than 56% DOC, and 
      their amount increased after oxidation, accounting for more than 64% DOC. Except 
      for organic pollutants with MW>10 kDa, those of other MW range were decomposed 
      better by AC/O(3) process than by O(3) process alone. GC/MS analysis showed that 
      AC/O(3)-BAC process was effective in removing phthalate esters (PAEs) and 
      persistent organic pollutants (POPs). PAEs' removal ratio reached more than 93% 
      and reduced with the increase of the length of the alkyl side chains and the 
      alkyl branch chains. POPs-polybromobiphenyls' removal reached more than 94% 
      except for 2,2',4,5',6-pentabromophenyl and decreased with the substitutional 
      bromines increase except for 2,2',5,5'-tetrabromobiphenyl, which could be 
      completely removed.
