摘要：

This review focuses on combined biological treatment with electrocoagulation as a post-polishing process to enhance treated effluents quality. We analyzed the main findings found in the literature and discussed many parameters used to optimize the process. Some studies used biological-pretreated wastewater while others applied combined system consisted of biological step followed by electrocoagulation step. The effluent quality in this combined system has been improved since more pollutants have been removed, especially when using an aluminum electrode. The main problems associated with the electrocoagulation process are energy consumption and electrode passivation. We presented many concluding remarks and recommendations for further studies.
