The residual dyes from different sources (e.g., textile industries, paper and pulp industries, dye and dye intermediates industries, pharmaceutical industries, tannery, and Kraft bleaching industries, etc.) are considered a wide variety of organic pollutants introduced into the natural water resources or wastewater treatment systems. One of the main sources with severe pollution problems worldw...
Industrial development worldwide has led to an increase in the amount of wastewater production leading to a considerable decrease in levels and quality of the natural water in the ecosystem. Textile dyes are an important class of pollutants in natural water ecosystem. Textile dyes are molecules designed to impart a permanent colour to textile fabrics. Effluent from textile dyeing units contain ...
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...
The purpose of a cross-sectional study was to investigate factors influencing the quality of life among Thai workers in textile dyeing factories. Samples included 205 Thai workers from five textile dyeing factories located in the suburban area of Bangkok in Thailand. Data were collected with a self-administered questionnaire. Scales of the questionnaire had reliability coefficients ranging from...
Textile dyeing wastewater is one of the major environmental problems in Turkey and is a common problem faced by many countries. These types of wastewaters are generally high in biological oxygen demand (BOD), chemical oxygen demand (COD), total solids, and strongly colored. Neither simple chemical nor biological treatment has proved to be adequate in removing the color and organic matter. It is...
Several small scale industries have formed cooperatives and established Common Effluent Treatment Plants (CETP) to treat wastewater in India. The wastewaters are subjected to primary treatment in the industry and thereafter discharged to be further treated at the CETPs. The management and treatment costs are shared by the member industries. The CETP under study is situated in North Western part...
Microalgae lipid feedstock preparation cost was an important factor in increasing biodiesel fuel hikes. This study was conducted with the concept of implementing an effluent wastewater as lipid production medium for microalgae cultivation. In our study textile dyeing industry effluent was taken as a lipid production medium for Neochloris sp. cultivation. The changes in physicochemical analysis ...
The enormous usage of synthetic dyes in various industries, chiefly textiles and paper industries, has posed a considerable health and environmental hazard. This dictates the need for amendment in the textile coloration technology by using natural origin pigments to replace the existing toxic, mutagenic and teratogenic dyes. Therefore, the scientists have recently focused their attention on app...
BACKGROUND AND OBJECTIVES Discharge of wastewater from textile dyeing industries has been a problem in terms of pollution and treatment of these waters is a great task. Keeping this in mind, the aim of our current research is to study the effect of various bioprocess variables on decolorization of an azo dye, Congo red, by a fungal isolate, Aspergillus niger HM11. MATERIALS AND METHODS CENTRA...
Textile industry is one of the most common and essential sector in the world. The textile industry consumes large quantities of water at its different steps of dyeing and finishing, among other processes. The non-biodegradable nature of dyes and their stability toward light and oxidizing agents complicate the selection of a suitable method for their removal. Moreover, toxicity bioassays have de...
