Electrocoagulation (EC) is a practical alternative to chemical coagulation for the treatment of drinking water that contains various pollutants, including humic substances. Nevertheless, the performance of EC for removal of algal organic matter (AOM) is still largely unexplored. In this review, the properties of AOM, the principles of chemical coagulation and EC, and the current state of knowledge on the coagulation of AOM have been outlined. The limited available literature on the EC of AOM is critically reviewed and let conclude that this is a promising technology for AOM removal. However, the studies on EC are inconsistent in their approaches, and they lack thorough optimization of operating conditions (resultant pH, coagulant dosing) and reports of residual metal concentrations. Some of the identified needs for future research include the complete optimization of EC for AOM removal, its direct comparison with chemical coagulation, and EC testing for the elimination of mixtures of AOM, humic substances, and inorganic particles. © 2023 The Authors.
