Methods for the Treatment of Wastewaters Containing Dyes and Pigments

Dyes and pigments are complex organic molecules that are widely utilized in different industries leading to effluent discharge, thus polluting water and disturbing the aquatic life. A wide range of physicochemical and biological methods have been introduced for the dye remediation. Constant research developments over the last decade resulted in the evolution of traditional physiochemical methods into advanced oxidation processes. Likewise, biological treatments have also advanced from using microorganisms to biocatalysts and integrated biochemical approaches for dye remediation.
