Overcoming barriers in the treatment of textile wastewaters using advanced oxidation processes
Currently, the textile industry is one of the most important economic sectors in many countries. Besides, it is known as a major consumer of water and consequently one of the largest groups of industries causing intense water pollution. Chemicals, including surfactants, dyes, resins, dispersants agents, inorganic salts, etc., play a variety of functions during the textile processing and are pre...
متن کاملDecolourisation of textile dyeing Wastewater by modified solar Photo-Fenton Oxidation
In a laboratory study, decolourisation of real textile dyeing wastewater by modified solar photo-Fenton (Steel scrap/ H2O2 ) process under irradiation with sunlight was examined. Batch experiments were conducted to determine optimal operating conditions .The optimal doses of H2O2 and steel scrap were 15 mL/L and 1 g/L, respectively at pH 3.Colour removal of 89% was obtained under optimum condit...
متن کاملOil Refinery Wastewater Treatment by Advanced Oxidation Processes for Chemical Oxygen Demand Removal using the Box-Behnken Method
This study investigated the reduction of the chemical oxygen demand from the Kermanshah oil refinery wastewater using Fenton and Photo-Fenton processes. The study investigated the effects of operating variables such as ultraviolet light intensity in values of 0, 15, and 30 W, ferrous ion concentration in values of 10, 50, and 90 mg/l, hydrogen peroxide concentration in values of 100, 500 and, 9...
متن کاملStudy on Trend of Biodegradability of Phenolic Compounds During Photo-Fenton Advanced Oxidation Process
Phenolic acids constitute a major group of pollutants which are recalcitrant to common biological treatment. In this study synthetic wastewater containing a mixture of p-coumaric and p-hydroxybenzoic acids was evaluated for photo-Fenton pretreatment. The changes in biodegradability (ratio of biochemical oxygen demand to total organic carbon (TOC)) and mineralization (TOC removal) were monitored...
متن کاملارزیابی عملکرد انواع فرآیندهای فنتونی در ترکیب با فرآیند انعقاد و لختهسازی متداول در تصفیه شیرابه محل دفن
Background: Advanced oxidation processes such as Fenton and photo-Fenton that have been applied effectively to oxide the persistent organic compounds in leachate and converts them to unharmful materials and final products. However, there are a few data about application of Fenton-like process in leachate treatment. Therefore, the aim of this study was to treat the municipal landfill leachate b...
