In order to satisfy the ever-growing demands in terms of quality,
variety, fastness and depth of color etc., the textile industries
now predominantly use synthetic dyes. Synthetic dyes or their
metabolites are toxic to the aquatic life and may have carcinogenic,
teratogenic and/or mutagenic effects on them [1]. Presence
of dyes in water bodies reduces photosynthetic activity and primary
production. Therefore, removal of dyes from effluent is of
prime importance to the environmental engineers. Since most of
the synthetic dyes are non-biodegradable, conventional primary
and secondary processes are inefficient in removing these contaminants
