The application of microalgae in the treatment of wastewater has attracted considerable scholarly interest as a viable and environmentally sustainable alternative. In recent years, numerous combinations of microalgae and bacterial consortia have been investigated to evaluate their efficacy in the remediation of wastewater originating from various sources. The essential criteria for assessing their performance encompass their capacity to eliminate nutrients such as nitrogen and phosphorus, in addition to heavy metals including arsenic, lead, and copper. This study examines the efficiency of microalgae-based systems in treating wastewater, comparing them with traditional treatment methods. It also delves into the characteristics of wastewater, conventional treatment techniques, and the mechanisms used for nutrient and heavy metal removal. Microalgae have demonstrated remarkable potential, achieving removal rates of up to 99.6% for nitrogen, 100% for phosphorus, and 13–100% for heavy metals across various wastewater types. Despite these advantages, microalgae-based treatment systems face certain challenges. Their performance is influenced by factors such as temperature, biomass productivity, osmotic pressure, pH, and oxygen concentration.
