Wastewater from the textile industry can contain a variety of polluting subst-ances including dyes. Increasingly, environmental legislation is being imposed to control the release of dyes, in particular azo-based compounds, into the enviro -nment. The ability of microorganisms to decolourise and metabolise dyes has long been known, and the use of bioremediation based technologies for treating t...
Since the present researches on pollution control for textile printing & dyeing industry are mainly focused on qualitative description up to now, instead of special quantitative analysis, based on the census data of pollution sources, this paper adopts literature collection method and single-factor variance components method for continuous variables to identify the factors influencing cost for ...
Textile wastewater represents challenging feed streams to be treated by membrane separation due to the complex composition and presence of reactive components. Here we fi rst briefl y present some characteristics of textile wastewater remediation where a key issue is (bio)fouling. We then present Membrane Bioreactors (MBRs) and Forward Osmosis (FO) membranes as both technologies have attracted ...
Aluminum sulfate (alum), ferrous sulfate, ferric chloride and ferric chloro-sulfate were commonly used as coagulants. However, a possible link of Alzheimer’s disease with conventional aluminium based coagulants has become an issue in wastewater treatment. Hence, special attention has shift towards using biodegradable polymer, chitosan in treatment, which are more environmental friendly. Moreove...
Since discharge limits are becoming stricter for industrial wastes, textile manufacturers are searching for 3fficient and economical methods of pollution reduction. This is typical of :he situation facing the textile ndustry, especially in the area of :olor pollution emitted into the zarth's waterways. Ozone treatment ;o remove color from wastewater :ould be a solution to the problem of
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...
We demonstrate the engineered growth of TiO(2) nanotube arrays on flexible carbon fibre sheets. The modification not only enables the textile to absorb ultraviolet light efficiently but also imparts large surface area and mesoporosity to the textile. This flexible nanoarchitecture greatly facilitates the purification of organic wastewater.
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) ...
Textile wastewater is notoriously known to contain strong colour, a highly fluctuating pH and significant COD (Chemical Oxygen Demand) values. Because of these characteristics, treatment of these effluents has been rather difficult. Traditional methods for dealing with textile wastewater consist of various combinations of biological, physical and chemical methods. Because of the large variabili...
The introduction of more stringent pollution regulations, in relation to financial and social pressures for sustainable development, has pressed toward limiting the volumes of industrial and domestic effluents discharged into the environment as well as to increase the efforts within research and development of new or more efficient wastewater treatment technologies. Considering both discharge v...
