Reviewing textile wastewater produced by industries: characteristics, environmental impacts, and treatment strategies

Water Science & Technology, Journal Year: 2022, Volume and Issue: 85(7), P. 2076 - 2096

Published: March 11, 2022

The textile industry is one of the most intensive industries in chemical products whose wastewater contains hazardous dyes, pigments, dissolved/suspended solids, and heavy metals. Hence, it important to effectively treat generated by this before releasing into environment. Although field treatment has made tremendous progress, developed methods should be improved further make them economically viable friendly. In review, characteristics are introduced. We have primarily focused on environmental impact toxicity wastewater. Toxic harmful contaminants must removed from reduce extent pollution caused when released rivers or reused. various techniques that used discussed. Finally, challenges faced, prospects been discussed detail.

Microbial Degradation of Azo Dyes: Approaches and Prospects for a Hazard-Free Conversion by Microorganisms

International Journal of Environmental Research and Public Health, Journal Year: 2022, Volume and Issue: 19(8), P. 4740 - 4740

Published: April 14, 2022

Azo dyes have become a staple in various industries, as colors play an important role consumer choices. However, these pose health and environmental risks. Although different wastewater treatments are available, the search for more eco-friendly options persists. Bioremediation utilizing microorganisms has been of great interest to researchers transition toward greener solutions demand through years. This review tackles repercussions azo its metabolites, available biological approaches eliminate such from environment with focus on use microorganisms, enzymes that involved degradation dyes, recent trends could be applied treatment dyes.

Use of bacterial isolates in the treatment of textile dye wastewater: A review

Heliyon, Journal Year: 2022, Volume and Issue: 8(6), P. e09632 - e09632

Published: June 1, 2022

The textile industry uses large amounts of dyes like reactive, azo, anthraquinone, and triphenylmethane to colour textiles. Dyes that are not used up during the colouration process usually end in water bodies as waste leading pollution bodies. This makes be one major contributors world. Bacterial agents isolated from various sources dye contaminated soil wastewater have shown ability effectively decolourise degrade these pollutants improved quality. review discusses bacterial isolates been successfully dyes, their mode removal well factors affect degradation ability. It further looks at latest treatment technologies incorporate microorganisms treat wastewater.

Biological Degradation of the Azo Dye Basic Orange 2 by Escherichia coli: A Sustainable and Ecofriendly Approach for the Treatment of Textile Wastewater

Water, Journal Year: 2022, Volume and Issue: 14(13), P. 2063 - 2063

Published: June 28, 2022

In this study, initially 11 different bacterial strains were tested for the degradation capabilities against Basic Orange 2 dye. initial screening with 78.90% activity, Escherichia coli emerged as most promising strain to degrade selected dye, and was then employed in subsequent experiments. For further enhancing capability of bacteria, effects various physicochemical parameters also evaluated. Among parameters, 20 ppm dye concentration, 1666 mg/L glucose a temperature 40 °C, 666 sodium chloride pH 7, 1000 urea 3-day incubation period use benzoate redox mediator (666 mg/L) found be ideal conditions get highest decolorization/degradation activities. Finally, all mentioned combined single set experiments, decolorization capacity bacteria enhanced 89.88%. The effect pH, time responsible optimum (p < 0.05), predicted from ANOVA (analysis variance) response surface methodology. metabolites collected after completion process characterized through Fourier transform irradiation (FTIR) gas chromatography mass spectrometry (GC-MS). From data obtained, proposed mechanism deduced where it assumed that azo bond broken by azoreductase enzyme resulting formation aniline 3, 4-diaminobezeminium chloride. converted benzene deamination action deaminase enzyme. ring, methylation, transformed into o-xylene, while p-xylene enzymatic action. These findings suggest is capable used bioremediation textile effluents containing dyes. However, may need investigated other dyes well.
