A comparative study for treatment of white liquor by different applications of Fenton process
In this paper, the treatability of white liquor by conventional (CFP), modified (MFP) and electro-Fenton oxidation processes (EFP) was investigated depending on the COD parameter. Based on the experimental results, up to 62.4%, 58.4% and 54.9% COD removals by the CFP, MFP and EFP were achieved, resp...

| description | In this paper, the treatability of white liquor by conventional (CFP), modified (MFP) and electro-Fenton oxidation processes (EFP) was investigated depending on the COD parameter. Based on the experimental results, up to 62.4%, 58.4% and 54.9% COD removals by the CFP, MFP and EFP were achieved, respectively. It was observed that adjustment of initial pH to acidic values is not required in the CFP. The optimal operational conditions were found to be [Fe2+] = 500 mg/L, [H2O2] = 1000 mg/L at pH 7.3 (original pH) in the CFP, [Fe0] = 1250 mg/L, [H2O2] = 1000 mg/L at pH 3 in the MFP, and I = 1.0 A, [H2O2] = 1500 mg/L at pH 3 in the EFP, respectively. As a result, the CFP has been determined as a more efficient alternative treatment method. |
