Electrocoagulation

Overview

What is Electrocoagulation?

Electrocoagulation (“EC”) is a broad-spectrum treatment technology that removes total suspended solids (TSS) and turbidity, metals, oils, bacteria and other contaminants from water.

How it Works

As water passes through the electrocoagulation cell, multiple reactions take place simultaneously. First, a metal ion is driven into the water. On the surface of the cathode, water is hydrolyzed into hydrogen gas and hydroxyl groups. Meanwhile, electrons flow freely to destabilize surface charges on suspended solids and emulsified oils. As the reaction continues, large flocs form that entrain suspended solids, heavy metals, emulsified oils and other contaminants. Finally, the flocs are removed from the water in downstream solids separation and filtration process steps.
