· | Water and large amounts of air are injected in to a columnar shaped device. |
· | The air and saltwater are forcefully mixed together, creating bubbles. |
· | The bubbles become coated with organics and proteins (adsorption), creating foam (or skimmate.) |
· | The foam rises up the column into a collection cup, located outside of the aquarium, where the organics and proteins are removed from the water. |
