Decolourization of Textile Azo Dye Direct Red 81 by Bacteria from Textile Industry Effluent

Experimental Studies on Decolourization of Azo Dye in Textile Effluent by using Bio Remediation Technique

Studies were carried out on the decolorization of azo dyes by Bacillus species from effluent of textile industries. About 10 bacterial strains were isolated from the effluent of textile industries, Bacillus sp. showed remarkable ability in decolorizing the widely utilized azo dyes. Phenotypic characterization and phylogenetic analysis based on 16S rDNA sequence comparisons indicate that these s...

Biodegradation of Textile Azo Dyes by Bacteria Isolated from Dyeing Industry Effluent

Water pollution caused by industrial effluent discharges has become an alarming trend worldwide, while textile industries are considered as the most polluting among all others. In recent years, bio-treatment took attraction in removing the unwanted colour and toxicity of textile effluents than other conventional treatment processes. The present study concentrates in the isolation and identifica...

Decolourization of azo dyes in textile wastewater by microbial processes

Adsorption of Reactive Red 194 Dye from Textile Effluent by Using Class F Fly Ash

A low cost adsorbent Fly Ash was used for the removal of Reactive Red 194 dye (RR 194 dye) from textile effluent. The Fly ash was activated by chemical treatment by N/2 H2SO4. Batch adsorption experiments were performed as functions of adsorbent doses, initial dye concentration, contact time, and pH. The percentage of colour removal was increased with decreasing dye concentration and increasing...

Biodegradation and decolourization of textile dye wastewater using Ganoderma lucidum

In this work, treatment of textile dye wastewater was carried in a batch reactor using Ganoderma lucidum. The characteristics of textile dye wastewater were studied. The effect of process parameters like pH, temperature, agitation speed and dye wastewater concentration on dye decolourization and degradation were studied. These parameters were optimized using response surface methodology (RSM). ...
