Textile Dyeing Wastewater Treatment
Textile industry can be classified into three categories viz., cotton, woolen, and synthetic fibers depending upon the used raw materials. The cotton textile industry is one of the oldest industries in China. The textile dyeing industry consumes large quantities of water and produces large volumes of wastewater from different steps in the dyeing and finishing processes. Wastewater from printing...
متن کاملDecolorization of Continuous Dyeing Wastewater by Ozonation
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
متن کاملEnhanced ozonation of textile wastewater by microbubbles
In this paper the microbubble technology was employed to increase the mass transfer rate of ozone as well as to enhance the ozone oxidation. Experiments were performed using the microbubbles generator and the bubble contactor, which is commonly used in ozonation system, for the purpose of comparison. The microbubble generator produced a milky and high intensity microbubble solution in which the...
متن کاملTextile Dyeing Wastewater Treatment by Coupling Fenton’s Reagent and Aerobic Sequencing Batch Reactor Processes
The oxidation of organic compounds and color removal of a synthetic dyeing effluent when treated with a combination of Fenton’s Reagent and biological oxidation in a sequencing batch reactor was evaluated in this work. A central composite design approach was used to find the best conditions of temperature, hydrogen peroxide and ferrous ion concentrations that maximize color and dissolved organi...
متن کاملDegradation of Terphetalic Acid from Petrochemical Wastewater by Ozonation and O3/ZnO Processes in Semi Batch Reactor
Background & Aims of the Study: One of the toxic pollutants in the wastewater of petrochemical industries is Terphetalic acid. In this study, the degradation and mineralization of Terphetalic acid in aqueous environment were studied by Ozonation and O3/ZnO processes in a semi batch reactor. Materials & Methods: This study is an experimental research on a laboratory scale. The st...
