This can decrease the load about the pumps, allowing for them to work more proficiently.
As organic and natural issue decays, it makes use of up oxygen. Aeration replenishes the oxygen. Bubbling oxygen with the water also retains the natural product suspended when it forces 'grit' (coffee grounds, sand and other smaller, dense particles) to settle out. Grit is pumped out in the tanks and brought to landfills.
