Advanced oxidation process in textile wastewater treatment using microreactor system

Abstract

The paper analyses the possibility of treating textile wastewater contaminated with the synthetic dye Acid Violet 109 in a microreactor system using advanced oxidation process. Wastewater from textile industry pose a risk to the environment. Effluents this type could be treated on many different ways but many of them have toxic byproducts and have also high operation and maintenance costs. Advanced oxidation processes show success with acceptable operating and maintenance costs. Alternative solution for dealing with wastewater contaminated with dyes is treatment in microreactor systems. Treatment of simulated wastewater with Fenton’s reagent in microreactor system was investigated. Microreactor set consisted of two plunger pump units, mixer and PTFE tube. Efficiency of decolourisation has been determined, with a focus on microreactor parameters, reactants flow and molar ratio of reaction mixture.
