Use of mechanical energy to inject air into water to cause a waste stream to absorb oxygen. Most traditional mechanical oxygenating machines function on a horizontal basis. These systems are made up with tubings and pumps, or a motor that activates a propeller. The system works by collecting the water and releasing it. A mixing of the resulting current takes place and air is absorbed as the water churns in. This aerated water is combined with the remaining water in the tank and continuously takes in more air for aeration purposes to mix. It should be noted that a multiple set of these systems can be utilized in a plant for maximum coverage.
