Electrocoagulation - Wikipedia
Electrocoagulation does not use particle size to provide physical separation. Chemical treatment addresses suspended solids, oil and grease, and some heavy metals, but may require the addion of various flocculants and coagulants as well as pH adjustments for proper treatment.

Electrocoagulation Technology for Wastewater Treatment
Electrocoagulation (EC) due to some advantages over chem. coagulation is becoming a popular process to be used for wastewater treatment. The aim of this paper is to investigate the effect of initial addn. of a chem. coagulant such as polyaluminum chloride (PAC) or alum on the COD removal efficiency of EC treatment of textile wastewaters.

Electrocoagulation versus chemical coagulation: Coagulation
Treatment by EC‐CC at 5 W for 20 mins using aluminum electrodes resulted in enhanced and consistent removal efficiencies of 26, 74, 76, and 85% for chemical oxygen demand (COD), reactive phosphorous (RP), total phosphorous (TP) and total suspended solids (TSS), respectively. Energy consumption was the main contributor to operating cost.

Electrocoagulation Process - an overview | ScienceDirect Topics
Basically electrocoagulation is electrochemical process based on application of sacrificial electrodes such as aluminum, iron, and zinc which undergo oxidation to form metal ions, which eventually act as coagulant and attract oppositely charged contaminants.

Electrocoagulation in the treatment of industrial waters and
treatment at a biological wastewater treatment plant. However, a thorough eco-nomic and ecological comparison of chemical coagulation and electrocoagulation is recommended, because these methods seem to be similar in pollutant destabilisa-tion mechanisms, metal consumption and removal efficiency in most applications.

Comparison of electrocoagulation and chemical coagulation
The electrocoagulation was more effective to eliminate TDS and presented higher removal of turbidity compared to chemical coagulation. Based on the analysis, the electrocoagulation is more efficient that the textile effluent treated can be reused or rejected without risk in the environment.
