Evaluation of Fenton oxidation process coupled with biological treatment for the removal of reactive black 5 from aqueous solution
Biodegradation of azo dyes is difficult due to their complex structures and low BOD to COD ratios. In the present study, the efficiency of using Fenton's reagent (H2O2 + Fe2+) as a pretreatment process to enhance microbial transformation of reactive black 5 (RB5) in an aqueous system was evaluated. The RB5 with an initial concentration of 250 mg/L was decolorized up to 90% in 60 h by using a ba...
متن کاملEvaluating the Fenton Process Efficiency in Removal of Reactive Red 2 from Aqueous Solution
Introduction: Dyes are visible materials and are considered as one of the hazardous components that make up industrial waste. Therefore it is removed from bodies of water, using various methods. In this regard, the Fenton oxidation process is one of the most effective ways to remove colored contaminants in aquatic environments, which has many applications today. Materials and Methods: In this...
متن کاملApplication of Fenton Oxidation Process for Degradation of Reactive Black 5 in Aqueous System
In the study, Reactive Black 5 (RB5) was removed from synthetic wastewater using Fenton's oxidation (FO) process. Batch experiments were conducted on the samples containing 50, 250 and 500 mg/L of RB5. The study was performed in the systematic optimum value of H2O2 and FeSO4 concentrations, pH and temperature. Optimum pH and temperature for 250 mg/L RB-5 were observed at 3.0 and 40°C respective...
متن کاملComparing Fenton Oxidation with Conventional Coagulation Process for RR198 Dye Removal from Aqueous Solutions
Background and objective: The wastewater discharged from textile industries is one of the main environmental pollutants that causes many problems for the environment if it is not treated or discharged. The present study compared Fenton oxidation process with coagulation and flocculation using the natural coagulant of Sodium Alginate in order to remove Reactive Red 198 Dye. Materials and method...
