Electrocoagulation (EC) is a broad-spectrum treatment technology tEC Video Image_r2hat removes total suspended solids (TSS), heavy metals, emulsified oils, bacteria and other contaminants from water. To view a short, informational video on the electrocoagulation (EC) process featuring our WaveIonics system, click here.


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.

Electrocoagulation can be integrated into new or existing treatment processes. Depending on the application, the final solids separation steps can be accomplished using settling tanks, dissolved air flotation, media filtration, ultrafiltration and other technologies to achieve water quality goals.
