Increasing population and industrialization are the key pollutant contributors in water bodies. The wastes generated by industries are highly hazardous for humans and the ecosystem and require a comprehensive and effective treatment before being discharged into water bodies. Over the years, many up gradations have been introduced in traditional water treatment methods which were expensive and ineffective especially for removal of toxic pollutants. Phycoremediation has been gaining attention due to its mutual benefit in wastewater treatment and for valuable algae biomass production. Wastewater, especially sewage and industrial effluents, is rich in pathogenic organisms, organic and inorganic compounds and heavy metals that adversely affect human and aquatic life. Microalgae use these inorganic compounds and heavy metals for their growth. In addition, they also reduce pathogenic organisms and release oxygen to be used by bacteria for decomposition of organic compounds in a secondary t
