The decolorization of C.I. Reactive Orange 36 (RO 36) by using Fenton-like process (Fe0/H2O2) was studied. Batch experiments were carried out for investigation of optimum operational conditions such as pH, H2O2 and Fe0 (iron powder) dosages. The results show that Fenton-like process is an efficient process to remove color from synthetic textile wastewater including RO 36 and polyvynil alcohol (PVA). The optimal conditions were experimentally determined and it was found to be initial pH = 3, [H2O2] = 50 mg/L, [Fe0]...

This study was focused on the application of Fenton (Fe+2/H2O2) process for the decolorization of colored synthetic wastewaters. Polyvinyl alcohol (PVA) and C.I. Reactive Blue 21 (RB 21) were used as model pollutants. The selection of the optimal operating conditions (initial concentration of H2O2 and Fe2+) was performed in a batch reactor. The optimal reacting conditions were experimentally determined and it was found to be initial [H2O2] 20 mg/L, [Fe+2] 37.5 mg/L for synthetic wastewater containing [RB 21] 50 mg...

This study examined the decolorization of one of the most commonly used reactive dye by using the Fenton-like process [Iron pyrite/ H2O2]. Raw iron pyrite ore contains 28,68 \% Fe. Oxidation experiments were run in 500 mL-glass beakers that were continuously stirred for up to 180 min at a constant rate of 200 rpm, after initiation of the Fenton process. A series of experiments were carried out at various concentration of hydrogen peroxide and raw iron pyrite ore while the pH value was kept constant at 3 in order t...

Noise is an important factor affecting human health psychologically due to lack of performance, hearing failures, decreases in heart beats, physiologically due to higher brain liquid pressure and sociologically due to lack of communication. Especially in closed working areas, it has significant negative effects on the performance. Noise control in closed working areas is generally done with boron added cellulosic mixture sprayed on the structure or surfaces with required thicknesses. In this study, noise was gener...

We report in this paper the preliminary results obtained during removal of pesticides from industrial wastewater by Fenton’s reagent. Fenton process is attractive alternative to conventional oxidation processes in effluent treatment of recalcitrant compounds. The aim of this study is to evaluate the efficiency of fenton process for the reduction of COD in wastewaters from pesticide industry. Several parameters were also studied: dose of Fe+2 and H2O2. The process of pesticide removal from industrial wastewater u...
