Researchers and scientists are paying increasing attention to wastewater dye treatment. Throughout the dyeing and finishing operations, it was discovered that 1% to 15% of the dyes were lost and, as a result, discharged into wastewaters. Consequently, a large quantity of these colors may be observed in the dyeing process effluents. The majority of synthetic dyes have been identified as hazardous compounds that have an impact on human and aquatic organisms. These dyes should be removed from wastewater using efficient treatment methods. Because of its highly variable pH, COD values, and color, the treatment of wastewater created by dyeing and finishing operations in the textile industry has been very complicated. The intense color might inflict irreversible damage to the receiving waters' natural system. Conventional wastewater treatment approaches comprise biological, physical, chemical, and hybrid approaches. This review has cited about 50 published articles concerned about using the adsorption method and focused on the core findings achieved by these publications. It revealed that the adsorption treatment method is a simple, reliable, adaptable, and relevant technology. Moreover, low-cost adsorbents have been performed, by several researchers, to remove contaminants from wastewater. [ABSTRACT FROM AUTHOR] |
