Background & Aims of the Study: Discharge of textile industry colored wastewater without enough treatment into natural water resources cause serious pollution. Most of the conventional wastewater treatment methods are not effective enough to remove these dyes from wastewater. In this study, efficiency of electrocoagulation process with iron electrodes for treatment of Reactive Yellow 14 dye...

conclusions considering the simplicity and efficiency of zero valent iron powder, this method is recommended for removing azo dyes from aqueous environments. results the results of this research showed ph = 3 and contact time = 120 minutes, increasing the zvi dose from 200 to 5000 mg/l in 100 mg/l dye concentration, increased the adsorption efficiency from 36.78% to 97.57%. rr-198 removal follo...

introduction malachite green (mg) has been used as a food coloring agent, food additive, medical disinfectant as well as a dye in silk, wool, jute, leather, cotton, paper, and acrylic industries. it is also extensively used as a topical fungicide and ectoparasiticide in aquaculture industries throughout the world. the findings reveal that this dye has now become one of the most controversial co...

BACKGROUND AND AIM Water resources pollution control is one of the main challenges of our time for researchers. Colored wastewater discharges caused by textile industry activities has added to the concern. In this study, removal of Acid Orange 7 dye (AO7) using Kenya Tea residue absorbent (granular) has been studied. METHODS This cross-sectional study was conducted in 2016. In this work, init...

This study investigates the anaerobic treatability of Acid orange dye in an anaerobic/aerobic sequential process. Laboratory scale anaerobic baffled reactor and fixed activated sludge reactor were operated at different organic loadings and hydraulic retention times. The effects of shock dye concentration on the chemical oxygen demand and color removal efficiencies were investigated in the anaer...

Introduction: Colored compounds which often are toxic and carcinogen is one of the environmental pollutants. These pollutants should be removed prior than discharge to the environment. The aim of this study was the evaluation of maize tassel powder efficiency for the removal of Reactive Red 198 dye from synthetic textile wastewater. Materials & Methods: This experimental study was performed in...

Synthetic dyes are among the most common contaminants of the environment. Therefore, the aim of this study was investigation the removal of Basic Blue 41 (BB41) and Methylene Blue (MB) from industrial effluents by useing raw and modified rice stems. In this study raw and modified rice stems treated chemically with Citric Acid (CA) and were used to explore the potentiality of rice stems for ...

Introduction: Disposal of the wastewater produced in the paper and paperboard industry without the refining process can add substances to the environment, which are harmful to humans, environment, and other organisms. With regard to process efficiency, the current methods used in wastewater treatment of this industry are economically unjustifiable. Therefore, in this research, the electrolysis ...
