ABSTRACT
Textile effluent comprise a mixture of dyes; hence, its review by is important to promote the existing techniques as well as to study new techniques to decolorize a mixture of dyes rather than a single dye solution. Marine biopolymers have potential applications in the bioremediation of dye and textile industry-polluted waters. Physical and chemical methods for treatment of dye wastewater are not commonly applied to textile industries due to the high costs and discarding problems. All colored compounds are not a dye and it might be not suitable for coloured substrate, for example, chemical copper sulphate will not use in any substrate for leathers, textile fibers, food stuffs, and oils. After processing, the dyes are directly released into the environment from the textile, plastic, cosmetics, and medicine industries. Most frequently used dyes in textile industries are reactive blue and red dyes; these are decolorized by biopolymer of starch and chitin, which has been reported as epichlorohydrin.
