چکیده
Textile industries have their own importance in Indian economy. It consumes large amount of water and as a result huge amount of waste water is generated. Textile effluent comprises of suspended solids, mineral oils, residual oils and is characterized by high BOD (from 700 to 2000 mg/l) and COD loads. It is necessary to treat the waste water so that it does not have any threat to the environment. This review paper discusses about characteristics of textile waste and various methods applied by the researches to treat the effluent discharged from textile industry. Conventional treatment methods like biological treatment methods are not applicable as mostly colors are identified as nonbiodegradable. So, modern techniques are to be implemented for effluent treatment. Some of them discussed here are advanced oxidation method, photo catalytic treatment by titanium oxide and membrane analysis. Key wordsBOD, COD, oxidation, photo catalytic, membrane

متن کاملChemical or electrochemical techniques, followed by ion exchange, for recycle of textile dye wastewater.
This paper examines the use of chemical or electrocoagulation treatment process followed by ion-exchange process of the textile dye effluent. The dye effluent was treated using polymeric coagulant (cationic dye-fixing agent) or electrocoagulation (iron and aluminum electrode) process under various conditions such as various current densities and effect of pH. Efficiencies of COD reduction, colo...

Introduction Graft copolymerization is one of the most promising technique uses to modify the properties of naturally available polymers with a minimum loss in their native characteristics. Methods and Materials Graft copolymerization is a very significant technique to add hybrid properties in backbone of polymers. The grafting generally initiated through the formation of free radical centers...
متن کاملRemoval of Dyes from Textile Industry Effluent: A Review
Effluent from the textile industry contains toxic compounds. These compounds contaminate the surface water, thereby making it unfit for irrigation and drinking. Since farmers use water from the rivers for agricultural purposes and the residents of the town, use both the surface and underground water from the same area as potable water, it is quite unsafe to discharge this effluent into water bo...
