A Review of Various Treatment Methods for the Removal of Dyes from Textile Effluent

Wastewater generated by the textile industry has been a major environmental concern for long. Production of fiber involves various steps and uses lot chemicals, dyes, water. Therefore, effluent produced from needs proper purification before discharging into water body. The current review summarizes physical chemical methods like ion exchange, coagulation-flocculation, membrane separation, distillation, oxidation, ozonation, etc., wastewater treatment. Along with this, adsorption methods, adsorbents used to purify wastewater, mechanism involved in have also discussed. biological method utilizes microbes (bacteria, fungi, algae, yeast) as whole enzymes (laccase azoreductase) secreted them treatment, which considered more feasible than methods. are better other techniques due their ability degrade diverse classes dye, less accumulation harmless sludge, cost-effective safer approach disposal effluent. While expensive generate toxic is difficult decompose.
