The applicability of Fenton and photo-Fenton processes as a pretreatment stage to

combined wastewater was investigated. The wastewater was obtained from the inlet of

the aeration tank in 42 Evler industrial and domestic wastewater treatment plant. The effects

of different process variables such as initial Fe2 (c0 833 mmol L–1) and H2O2

(c0  65165 mmol L–1) concentrations, pH (37.75) and reaction time (t  5180 min)

were evaluated. The Fenton process was investigated which under the operating conditions

(pH 3, cFe2+  12 mmol L–1, cH2O2  130 mmol L–1) 100 % color and 44 % total

organic carbon (TOC) removal were achieved. However, 71 % TOC removal was

achieved at pH 7.75 by coagulation but color was poorly removed (c  20 mmol L–1

Fe2, c  165 mmol L–1 H2O2). In the photo-Fenton process, 84 % TOC and 87 % color

removal were achieved in 30 min reaction time (pH 3, cFe2  26 mmol L–1,

cH2O2  130 mmol L–1).
