A review of the literature on the mutagenicity of textile dye products is presented in this article. This review discusses genetic hazards associated with the production and use of textile dyes throughout the world. Mutagenicity of azo and non azo dyes has been considered due to extensive recent data on the carcinogenicity and mutagenicity of this group of dyes. In addition, a section on Salmon...
Introduction: The Powdered Activated Carbon Treatment (PACT) has been proposed as an alternative in wastewater treatment and wastewater biomass protection against toxic substances. This study aims to evaluate PACT performance in treating dyes, acid orange, and remazol brilliant reactive blue. Materials and Methods: This empirical- applied research was carried out in pilot scale in which differ...
In order to improve the color saturation of textile structured chromogenic photonic crystals, this paper proposes that dye adsorbed PSt structural elements (reactive dyes/PSt microspheres) on outer surface can be used construct electrochemically crystals mulberry fabrics by digital printing. method, adsorption conditions and model dyes colloidal microspheres were studied. The structure morpholo...
Accumulation of large quantity of non-biodegradable textile dyes into the environment made much attention to finding a suitable solution for the degradation of textile dyes. In this present study, decolorization efficiency of two different treatment technologies such as Photo-Assisted Chemical Oxidation (PACO – UV/H2O2) and Electrocoagulation (EC) on Reactive ...
Background and Objective: Reactive Red 198 is a mono azo dye widely used in the textile industry of Iran. The toxicity of reactive dyes is higher than other dyes and causes disorders such as irritation, cancer and mutation in humans. The overall objective of this study was to determine the efficiency of a Constructed Wetland pilot system with conventional and baffled horizontal subsurface flow ...
Bacillus subtilis C3, a commercial textile dye-decolorizing and -degrading bacterium, was isolated from the common effluent treatment plant (CEPT) of the Jetpur textile dyeing and printing industrial sector situated in the district of Rajkot, Gujarat, India. Here, we present the annotated 4.18-Mb draft genome sequence of B. subtilis C3, providing information about the metabolic pathways involve...
Textile wastewater is characterized by strong color, saturation of unfixed dyes and their residues, and organic and inorganic chemicals, such as bleaches, detergents, optical brighteners, fixing, sequestering and finishing agents, carriers, surfactants, equalizers, It is characterized by consumption of high amount of water and production of large volumes of wastewater from various processes, su...
This paper presents an overview of textile wastewater treatment by catalytic ozonation, highlighting the parameters process and accompanying mechanisms. Since more than 800,000 tons dyes are produced annually thousands cubic meters highly polluted have been emitted into environment every day, this issue has become environmental concern. Due to high oxidative potential ozone (2.08 V) hydroxyl ra...
In this study, the Bohart and Adams’ model taking into account bed depth, and influent dye concentration was studied to exhibit adsorption process of textile dyes (Basic Blue 41 – BB41 and Reactive Black 5 – RB5) in glass columns using tree barks (Eucalyptus camaldulensis). Adsorption capacity coefficient values are determined using the Bohart and Adams’ bed depth service model. The model indic...
