Electrocoagulation (EC) is an innovative wastewater treatment technology increasingly adopted in Sewage Treatment Plants (STPs) for its efficiency and sustainability. In this process, an electric current is applied to metal electrodes submerged in wastewater, causing the release of coagulant agents that destabilize and bind with suspended contaminants. These pollutants then form larger, heavier particles that can be easily removed through sedimentation, flotation, or filtration.
Minimal or no use of external chemicals.
Removes up to 90% of contaminants including heavy metals, TSS, and COD.
Low operating costs due to reduced chemical usage and sludge generation.
Easy to integrate into existing wastewater treatment plants.
Produces less sludge and supports sustainability goals.
