The Role of Microalgae in Textile Dye Industrial Waste Water Recycle (phycoremediation)

Many industrial areas in the world, show increases in generating of wastewater nowadays. Industrialization is considered as the key factor for the development of countries in economic terms. The recognition that environmental pollution is a worldwide threat to public health has given rise to new initiatives for environmental restoration for both economic and ecological reasons. The best methods to treat the textile dye industrial waste water by using a biological treatment method of cultivation of microalgae. Microalgae have gained a great deal of attention as remove contaminants from wastewater, potential biodiesel raw material because of their high growth rates and ability to accumulate oil and bind carbon dioxide. The normal primary and secondary treatment processes of these wastewaters have been introduced in a growing number of places, in order to eliminate the easily settled materials and to oxidize the organic material present in wastewater. Microalgal culture offers an interesting step for wastewater treatments, because they provide a tertiary biotreatment coupled with the production of potentially valuable biomass, which can be used for several purposes. The final result is a clear, apparently clean effluent which is discharged into natural water bodies. In the review, we have highlighted on the role of micro-algae in the treatment of wastewater and Biomass production. The biobased technology otherwise called phycoremediation of waste water.
