The wastewater bioremediation is an emerging research area to meet the existing/increasing water crisis challenges. Heavy metals persist in bodies, which can bioaccumulate food chain and cause serious health environmental problems. deteriorating effects of heavy both on human environment have drawn great attention become a major study. Phycoremediation one most promising areas being explored currently. conventional methods such as chemical precipitation, ion exchange, membrane filtration, floatation, coagulation-flocculation electrochemical inherit limitations bringing down cost treatment, increasing efficiency formation toxic sludge secondary pollution. phycoremediation serves be green technology. This review highlights current advances using different species microalgae treat various industrial effluents mechanism removal from them. A comprehensive look into microalgae-based systems (MBSs) has been covered assess through extracellular intracellular mechanisms biosorption, bioaccumulation detoxification metals. It brings focus all technologies times that utilised urban systems. In addition, challenges, bottlenecks future prospects are also discussed with achieving circular bioeconomy management.
