The extensive application of dyes in the textile industries and their discharge in the wastewaters leads to numerous environmental pollutions; therefore, treating these wastewaters by efficient and eco-friendly methods is a necessity. In this study, potent strains were isolated by the enrichment technique according to their maximum dye sorption at the lowest possible time at 500nm. Consequently...
Treatment of textile wastewaters by electrocoagulation using iron and of aluminum electrode materials has been investigated in this paper. The effects of relevant wastewater characteristics such as conductivity and pH, and important process variables such as current density and operating time on the chemical oxygen demand (COD) and turbidity removal efficiencies have been explored. Furthermore,...
as dyes are the most important pollutants of many industrial wastewaters. a large amount of reactive black 5 enters the environment in iran because of the use of this dye in iran's textile industries, so the goal of this study was to survey the catalytic ozonation process with bone char in removal of reactive black 5 dye from synthetic wastewater. in this experimental study bone char (bc) was p...
Backgrounds and Objectives: Dyes are organic materials with complex structures, toxic, carcinogenic, teratogenic,nonbiodegredable properties and!the most!important pollutants of textile industrial wastewaters. The goal of this study was to survey the feasibility application of bone char (BC) as a sorbent for the of methylene blue (MB) from synthetic wastewater.The sub goals of the resear...
in this research, the removal of malachite green dye from textile wastewaters using polyaniline coated onto sawdust (pani/sd) has been investigated. ammonium peroxodisulphate was used as chemical oxidant for polymerization of polyaniline directly on the surface of sawdust. the effects of some important parameters such as ph, initial concentration, sorbent dosage, exposure time and temperature o...
Introduction: Textile industries, due to a high volume of wastewater and harmful environmental factors such as a variety of dyes, are significant industries in industrial wastewaters treatment. So, the aim of this study was to examine the efficiency of dye removal from the textile industry wastewater using the titanium dioxide photocatalytic process under UV-LED light irradiation (UV-LED/TiO2) ...
