Within this context, the individual and interactive effects of critical process parameters such as Fe2\u2009+\u2009, H2O2 concentrations, initial chemical oxygen demand (COD) and reaction time was assessed. The process response (output) variables were chosen as percent color, COD and total organic carbon (TOC) removal efficiencies. Optimum working conditions in terms of color and organic carbon removals were established to be Fe2\u2009+\u2009 = 3\u2009mM; H2O2 = 25\u2009mM; reaction time = 10\u2009min at pH 3 and an initial COD content of 245\u2009mg\/L. Under these conditions, 96% color, 82% COD and 51% TOC removals were obtained. The established polynomial regression models describing color, COD and TOC removals satisfactorily fitted the experimental data and could be used to predict Fenton's treatment results at statistically significant rates. Optimized treatment results were compared with those obtained via electrocoagulation treatment under optimized conditions (applied current = 50\u2009A\/m2; reaction time = 15\u2009min; initial pH = 7 for an initial COD content of 245\u2009mg\/L). The relative inhibition of heterotrophic oxygen uptake rate was measured to examine the inhibitory effect of azo dye synthesis effluent before and after Fenton's oxidation and electrocoagulation with respect to synthetic domestic wastewater. Untreated azo dye production wastewater exhibited a slightly inhibitory effect that was appreciably reduced but not entirely removed after Fenton's oxidation, whereas no inhibition of mixed bioculture was observed for azo dye synthesis effluent subjected to electrocoagulation treatment.<\/jats:p>","DOI":"10.2166\/wst.2010.256","type":"journal-article","created":{"date-parts":[[2010,7,2]],"date-time":"2010-07-02T10:32:07Z","timestamp":1278066727000},"page":"209-216","update-policy":"http:\/\/dx.doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":10,"title":["Modeling and optimization of acid dye manufacturing wastewater treatment with Fenton's reagent: comparison with electrocoagulation treatment results and effects on activated sludge inhibition"],"prefix":"10.2166","volume":"62","author":[{"given":"Idil","family":"Arslan-Alaton","sequence":"first","affiliation":[{"name":"Civil Engineering Faculty, Environmental Engineering Department, Istanbul Technical University, 34469 Maslak Istanbul, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B.
