AB  - This study investigated the best way to combine nanofiltration (NF) and Fenton 
      with membrane bioreactor inoculated with Saccharomyces cerevisiae (MBRy) for the 
      treatment of landfill leachate, aiming at compliance with legislation and water 
      reuse. Firstly, the permeate from MBRy was treated by Fenton process followed by 
      NF (MBRy - Fenton - NF). Another alternative evaluated was the polishment of MBRy 
      permeate by NF and treatment of NF concentrate by Fenton process (MBRy - NF - 
      Fenton((concentrate))). COD removal in the Fenton step was optimized according to 
      central composite design (CCD) and 85.5% removal was obtained at pH = 3, 
      Fe(2+):H(2)O(2) molar ratio = 1:9.81 and C:H(2)O(2) molar ratio = 1:1.14. 
      Increased toxicity was observed with the Fenton application (EC(50) = 2.45%). The 
      NF showed the best performance treating the MBRy permeate. High permeate flux 
      (8.9 +/- 1.6 L h(-1) m(-2)) and ion rejection (82 +/- 4.2%), and low membrane fouling 
      was observed in this condition. Although both NF permeate presented potential for 
      reuse, the final COD concentration was lower in the MBRy - Fenton effluent (88 mg 
      L(-1)). The Fenton application for the NF concentrate was able to remove 87.24% 
      of COD. With a preliminary economic analysis, it was verified that the MBRy - NF 
      - Fenton((concentrate)) combination is the most advantageous due to the lower 
      chemical reagent and membrane area requirements. Thus, this route presents itself 
      as an alternative for landfill leachate reclamation.
