Abstract

In this study, the treatment efficiency of different advanced oxidation (Fe+2/H2O2, Fe+3/H2O 2, O3) and chemical coagulation processes were investigated. Wastewater samples were taken from two different textile industries. Optimum efficiencies in color and COD removal were determined based on the applications of different chemical species and pH. 150 mg/L FeSO 4 at pH 12 has provided the maximum color and COD removal efficiency in chemical coagulation experiments for textile industry 1. For textile industry 2, maximum color and COD removal efficiencies were obtained with Fe +2/H2O2 (Fenton) process at pH 3 (FeSO 4 200 mg/L and H2O2 200 mg/L dosages). The operating costs of all proposed treatment systems were also evaluated in this study.
