Floating surface aerators work in a similar manner to fountains, but they do not offer the same aesthetic appearance. They extract water from the top 1–2 feet of the water body and utilize air-water contact to transfer oxygen. Instead of propelling water into the air, they disrupt the water at the water surface.
Soil aeration is the mechanism of improving the exchange of gases between the atmosphere and soil. Through soil microbial activity and plant root respiration, certain gases such as oxygen will be depleted in the soil, while others, such as carbon dioxide, will build up in the soil. [1]
After aerating, Chip says to overseed bare patches before the trees begin to regain their foliage. Taking advantage of this pivotal in-between stage will allow typically shaded areas of grass to ...

The ATS process generally consists of the following phases: [2] Pre-treatment stage to remove large solids and other undesirable substances. Aeration stage, where aerobic bacteria digest biological wastes. Settling stage allows undigested solids to settle. This forms a sludge that must be periodically removed from the system.

Aeration (also called aerification or aeriation) is the process by which air is circulated through, mixed with or dissolved in a liquid or other substances that act as a fluid (such as soil). Aeration processes create additional surface area in the mixture, allowing greater chemical or suspension reactions.
An air diffuser or membrane diffuser is an aeration device typically in the shape of a disc, tube or plate, which is used to transfer air and with that oxygen into the sewage or industrial wastewater. Oxygen is required by microorganisms/bacteria residents in the water to break down the pollutants.
