An Air Binding is a situation where air enters the filter media and harms both the filtration and backwash processes.

In the context of the environment, "air binding" typically refers to a condition that can occur in wetland or aquatic ecosystems, where the soil becomes saturated with water and is unable to drain properly. When this happens, air becomes trapped in the soil, and the soil becomes less able to support plant growth.

Air binding can have a number of negative impacts on wetland and aquatic ecosystems. For example, it can reduce the amount of oxygen available to plants and animals, and it can also cause the soil to become more acidic, which can be harmful to some species.

Air binding can be caused by a variety of factors, including excessive rainfall, poorly drained soils, and the overuse of irrigation. It can be difficult to remediate once it occurs, but there are a number of management practices that can help to prevent air binding from occurring, such as improving drainage, reducing irrigation, and adding organic matter to the soil
