Phycoremediation is one of the leading technologies currently under trial to improve nutrient rich wastewater quality. The technology employs solar driven algal cells for remediation of wastewater rich in organic, inorganic or xenobiotic compounds. Studies confirm that the final product is a clean and clear effluent ready to be discharged into natural water bodies. Thus, algal technology may prove to be an elegant solution to the current crisis on wastewater management. However, currently, the technology faces limitations in terms of availability of optimal strains. So far, limited work has been done to make the current strains genetically robust and more tolerant to the existing pollutants. In this chapter, we will highlight the role of microalgae in the treatment of wastewater as also discuss the current challenges on further development and commercialization of the phycoremediation technologies.
