As natural and organic matter decays, it utilizes up oxygen. Aeration replenishes the oxygen. Bubbling oxygen with the water also retains the natural and organic materials suspended although it forces 'grit' (coffee grounds, sand as well as other smaller, dense particles) to settle out. Grit is pumped out with the tanks and taken to landfills.
