Methods of Dye Removal from Dye House Effluent—An Overview
Environmental Engineering Science, 2008Wastewater from dye houses can have strong impacts on the aquatic environment. Due to its complex chemical structure, dye is one of the most difficult constituent in the textile wastewater to treat. The treatment of dye house wastewater constitutes a major economical and environmental issues.

Rapid urbanization and industrialization result in the discharge of harmful and toxic waste into the water bodies which are not easy to degrade thereby causing environmental pollution. Out of so many waste discharges, dye waste is noxious for aquatic life and for human as well; therefore, removal of these toxic compounds from water is one of the major ...

Removal of dyes and industrial dye wastes by magnesium chloride
Water Research, 2000Magnesium chloride, as compared to alum and polyaluminium chloride (PAC) is a less commonly used coagulant in the field of wastewater treatment, with a cost in between alum and PAC. It has been used in this study as a coagulant to investigate the eAectiveness in the chemical precipitation method for the removal of colouring matters.

Waste Management, 1998
Adsorption techniques employing activated carbon have been found to be reasonably effective in the removal of some of the ionic impurities in water. However, economic considerations may require the use of inexpensive sorbents which are either naturally available or available as waste products from manufacturing processes. Slag is one such waste product

Removal of organic dyes by magnetic alginate beads
Water Research, 2008This study deals with the development of a clean and safe process for water pollution remediation. We have synthesized a magnetic adsorbent in order to develop a solid-phase extraction process assisted by a magnetic field. To follow an 'ecoconception' approach, magnetic beads containing magnetic nanoparticles and activated carbon are prepared with a ...

Removal of disperse dyes by the fungus Cunninghamella polymorpha
Journal of Bioscience and Bioengineering, 1999A disperse dye-removing fungus, Cunninghamella polymorpha, was isolated from soil. C. polymorpha efficiently removed an average 93% of 17 tested disperse dyes in 120 h, and 90% of C. I. Disperse Blue 60 was removed even at a high concentration of 500 mg/l. The dye removal was due to the sorption of dye to the fungal cells.

Biomimetic dynamic membrane for aquatic dye removal
Water Research, 2019This study utilized physical adsorption and filtration of carbon nanotubes (CNTs) and laccases to fabricate biomimetic dynamic membrane (BDM) for the advanced treatment of dye wastewater. In BDM, the adsorption, enzymatic degradation and membrane separation demonstrated a synergism effect on pollutant removal.

Waste based chitosan membranes for dye removal
International Journal of Biological MacromoleculesWater contamination is an important global issue. This study explores dye removal potential of chitosan-based membranes with lemon waste and Cu2+, selected based on circular economy and green chemistry. Lemon waste and chitosan were used to recover Cu2+.

Removal of basic dyes by biosorption
Green macroalga Caulerpa lentillifera was found to have adsorption capacity for basic dyes, Astrazon Blue FGRL, Astrazon Red GTLN, and Astrazon Golden Yellow GL-E. The initial dye concentration was in the range from 100-1800 mg l[superscript -1] . The dried algal sorbent was ground and sieved into 3 sizes: S (0.1-0.84 mm), M (between 0.84-2.0 mm), and ...openaire +1 more source
