Textile effluents vary in composition, and thus, numerous approaches have been developed for treatment of dyeing waste water with several steps being combined to obtain effluent suitable for discharge. Development of microbial degradation methods, which are broadly applicable, poses a challenge, since there were 9788 different generic names of colorants listed in the Colour Index in 1982. Any single biological method can only be used for a limited number of these dyes. Currently, the most widely studied dyes appear to be those which have azo structures. Low cost renewable materials appear to be attractive for further study with respect to treatment of textile effluents by adsorption. Such adsorbents have already been used for the dyeing effluent treatment and could play an important role in the future textile mill effluent treatment, if appropriate regeneration techniques are demonstrated.
