In this research, the performance of the wastewater treatment process of Kaveh Petrochemical Methanol was evaluated using microalgae Chlorella vulgaris. The wastewater contains metals such as Ca, Cu, Fe, K, Mg, Mn, Na, P, S, and Zn, which, upon entering aquatic environments, contribute to pollution and the disruption of local ecosystems.The aim of the study is biological wastewater treatment, followed by the production of biodiesel from lipids obtained from Chlorella vulgaris biomass after wastewater treatment. One advantage of this method is the utilization of carbon dioxide present in the air by microalgae for growth and reduction.The wastewater treatment process removes organic matter, metals, and ammonia from the discharged effluent, contributing to the recovery of bio-based materials in the environment. This method can potentially lead to the production of biodiesel using abundant and cost-effective lipid sources. In this research, Chlorella vulgaris microalgae were cultured in wastewater containing metals and organic substances for 14 days. Afterward, the wastewater was evaluated, and the results showed removal percentages for metals Ca, Cu, Fe, K, Mg, Mn, Na, P, S, and Zn were 42, 86, 93, 76, 88, 76, 92, 46, 24, and 49%, respectively.
