PREAMBLEPREAMBLE
Dye effluents and waste streams/ wastewaters are generally Dye effluents and waste streams/ wastewaters are generally obtained as a result of manufacturing processes for the obtained as a result of manufacturing processes for the preparation of textiles/fabrics in a wide extent. The waste preparation of textiles/fabrics in a wide extent. The waste streams include varying organic and inorganic materials streams include varying organic and inorganic materials rendering to be unsuitable for reuse and undesirable for release rendering to be unsuitable for reuse and undesirable for release into the biosphere. Wastewater containing dyes presents a into the biosphere. Wastewater containing dyes presents a serious environmental problem due to its high toxicity which serious environmental problem due to its high toxicity which leads to ground water and surface water pollution. Therefore the leads to ground water and surface water pollution. Therefore the removal of the high stable dyes from the textile effluents is of removal of the high stable dyes from the textile effluents is of prime importance.prime importance.
Such dye effluents and wastewaters are characterized by their Such dye effluents and wastewaters are characterized by their intense color, high chemical oxygen demand (COD), salinity and intense color, high chemical oxygen demand (COD), salinity and fluctuating pH which tend to various environmental and fluctuating pH which tend to various environmental and pollution problems when discharged untreatedpollution problems when discharged untreated
