Polyvinyl alcohol-containing desizing wastewater discharged within final textile wastewater has a great impact to the environment due to its poor biodegradability. An improved lab-scale hybrid anaerobic baffled reactor was developed to treat desizing wastewater. The modification was achieved by increasing the height of hybrid anaerobic baffled reactor and application of proper effluent recycle ...

nanofiltration (nf) has become a widely accepted process not only for producing drinking water but also for recovering wastewater in industrial processes or removing pollutants from industrial wastewater effluent. in the textile industry, the treatment of various dye baths with nf at room temperature have already been studied and was found feasible at lab-scale and pilot scale. the aim of this ...

Textile wastewater contains a number of dyes which are known to be toxic and carcinogenic. In this study the results show that the Fenton (Fe2+/H2O2) process is an efficient method for the removal of Acid Brown 14 (A.BR14) and Cationic Blue 41 (C.B41) dyes from textile wastewater. In this method, two reagents Fe2+and H2O2 are used and do not require any additional energy. Several experiment...

Synthetic dyes are integral part of many industrial products. The effluents generated from textile dyeing units create major environmental problems and issues both in public and textile units. Industrial wastewater treatment is one of the major problems in the present scenario. Though, the physical and chemical methods offer some solutions to the problems, it is not affordable by the unit opera...

Azo dyes are one of the oldest industrially synthesized organic compounds characterized by presence of Azo bond (-N=N-) and are widely utilized as coloring agents in textile, leather, cosmetic, paint, plastic, paper, and food industries During textile processing, inefficiencies in dyeing result in large amounts of the dyestuff (varying from 2% loss when using basic dyes to a 50% loss when certa...

This paper reports application of cetyltrimethylammonium bromide (CTAB) coated magnetite nanoparticles (Fe3O4 NPs) as a novel adsorbent for removal of two types of disperse dyes, including disperse red 167, and disperse blue 183, from wastewater of textile companies. The effect of parameters including type of surfactant, pH of solution, surfactant concentration, and amount of salt, was investig...

The long-term performance of a submerged membrane fungi reactor was observed while a synthetic textile wastewater containing either or both of the two structurally different azo dyes was continuously fed. Compared to the Acid Orange II dye (simpler structure), higher biosorption but slower biodegradation of the polymeric dye (Poly S119) was observed in sterile batch tests. In the membrane biore...
