Applications of Electrocoagulation: a Review Duang Buddhasukh

This short review was compiled as a result of the authors' own involvement in utilising electrocoagulation process in a major part of their research work. Hopefully, this review will also cause an awareness on the part of the reader of the versatility of the electrocoagulation process, the process that has been around for more than a hundred years now. However, due to a low level of environmental awareness and a lack of sufficient financial incentives, this technology was more or less abandoned and not developed further for a long period of time. Now, the increase in environmental restrictions on effluent wastewater, the focus on cost-effective alternatives, the trend to minimise wastes, and the new uses of the technology have been responsible for the resurgence of electrocoagulation as an important tool for various applications.
