Electrocoagulation is a treatment process that utilizes electrical currents to destabilize contaminants in wastewater, making it an effective method for removing suspended solids and other pollutants. The primary function involves the introduction of an electrical current that facilitates the coagulation of fine particles and contaminants, which then aggregate into larger flocs. These aggregated solids can subsequently be removed through sedimentation or filtration.

The effectiveness of electrocoagulation lies in its ability to treat a wide variety of contaminants, including oils, heavy metals, and organic matter, by promoting the aggregation of these substances into larger, more easily separable particles. This process is particularly valuable in contexts where traditional methods may be less effective, enabling improved overall water quality in the treated effluent.

The other options do not encapsulate the main purpose of electrocoagulation in the context of wastewater treatment. While filtering large solids or neutralizing hazardous chemicals can be functions of different treatment processes, they do not specifically define the scope of electrocoagulation. Similarly, increasing the temperature of wastewater is unrelated to the coagulation process and does not contribute to removing contaminants efficiently.
