Electrocoagulation for drinking water treatment: A review

Abstract

In this era, raw water pollution often occurs, and conventional processing can sometimes not treat it. Raw water as a water source for drinking water has to meet physical, chemical, and biological parameters in accordance with a predetermined standard. One of the parts of the advanced electrochemical process is electrocoagulation, which has been widely used to treat various types of wastewater and water. Chemical coagulation and electrocoagulation had the same process but a different mechanism. The way aluminum or iron is delivered is the difference in the mechanism. This article focuses on the effects of various operating parameters and recent developments in the electrocoagulation for the drinking water treatment process. Their optimum ranges for maximum pollutant removal and various pollutants removed by this process are observed.
