Compressed air is then injected into the mixture by porous diffusers located at the bottom on the tank. Mainly because it bubbles for the floor, the subtle air provides oxygen as well as a swift mixing motion. Air will also be additional by the churning action of mechanical propeller-like mixers Positioned for the tank area.
