Environmental pollution has become a worldwide concern for developing as well as developed nation. During the last two decades, a serious attention has been given in the management of environment pollution caused by hazardous material. Currently, water pollution is a serious threat for mankind which continuously deteriorated due to industrial revolution. Various physicochemical processes such as precipitation, evaporation, ion exchange, filtration, etc. are being used in the treatment of wastewater. However, several disadvantages are associated with these processes. Algae are the photosynthetic microorganism having potential to grow in both fresh and marine water bodies and can be safely utilized for contaminant removal from wastewater without imposing any hazard to the environment. The term “phycoremediation” is now being used for the process which involves algae for the removal or biotransformation of pollutants from wastewater. Apart from removal of contaminants, they also reduce biological and chemical oxygen demand of water bodies. Therefore, algae are now emerging as a desirable treatment option and could be a sustainable biomass feedstock for biofuel production. So, the dual use of microalgae, i.e., phycoremediation, as well as biomass production is a feasible option. Therefore, this chapter provides a detailed account regarding the wastewater, phycoremediation, nutrients and heavy metal uptake mechanism, and potential benefit and limitation of using wastewater as a source of nutrients for cost-effective biofuel production from microalgae.
