Abstract

Several different approaches are employed for wastewater treatment to reduce the quantity of harmful substances that are let out into the surroundings each year from a variety of industries. By electrochemically dissolving sacrificial anodes, often formed of iron or aluminum, the Electrocoagulation (EC) technique destabilizes contaminants that are dissolved, suspended, or emulsified. It has the capacity to eliminate a range of pollutants from various types of wastewaters, including organic and inorganic contaminants. The pH, electrode, operating period and current density are only a few of the variables that affect how well the EC process works. Reviewing the most pertinent newly published material is the aim of this study. The electrode passivation and energy use issues with the EC technique are the key difficulties. EC has benefits over other conventional technologies, including lower operational expenses and lower energy use. A survey of the literature covering electrocoagulation electrochemical treatment of wastewater published during the previous 32 years was given. The review discusses issues about electrocoagulation, the background electrocoagulation hybrid process for industrial and leachate wastewater treatment and its cost effectiveness.
