Electrocoagulation is used to precipitate dissolved organic and inorganic water contaminants and cause fine particles to flocculate to allow removal by standard filtration methods.

 

 

     At left is a prototype electrocoagulation cell, submitted toThe Center to test what materials are successfully removed by electrocoagulation, what metals make the best electrodes for various contaminants, and the rate at which elelctrodes sacrifice during operation. Notice the layer of white froth at the water surface. This contains the contaminants that have been coagulated from the water sample.

         At right is Eric, one of our chemistry students, using ion-specific electrodes to measure the electrocoagulator's effect on dissolved metal ions. Whenever possible, students are included in our studies to give them "hands-on" experience.
