Identifying The Best Pair of Electrode For Industrial Wastewater Treatment by Electrocoagulation

Abstract

Each year, a large number of businesses release a substantial quantity of wastewater into the environment. To treat this wastewater and lower the level of contaminants, many techniques are used. Sediment and light suspensions that float are two different types of contaminants that are removed from the wastewater during the electrochemical process of emulsification. By electrochemically dissolving sacrificial anodes, usually made of iron or aluminum, the electrocoagulation (EC) procedure disturbs pollutants that are suspended, dissolved, or emulsified. This method has the potential to remove both organic and inorganic pollutants that can be present in different types of wastewater. The pH, electrode type, operation time, and current density are some of the factors that affect how effective the EC process is. Examining the most pertinent recently released studies on this subject is the goal of this study. Electrode passivation and energy consumption are the two main issues with the EC technique. Using 36 different variations of electrode pair, the treated sample is tested different parameter. The best value for additional efficiency of E.C & Salinity for Al(+) and Zn(-) pair is 147.376 & 143.75 respectively. No other electrode pair have more than one higher parameter value. Compared to other conventional technologies, EC has benefits including lower operating costs and energy consumption. The following variables are controlled in this study: pH, BOD, COD, TSS, TDS and Salinity.
