___ is a term defined as bringing water into contact with air.

Aeration is the process of bringing water into contact with air. This physical interaction allows gases to transfer between the two phases—most importantly, it adds oxygen to the water and can help remove dissolved gases and volatile compounds. In practice, aeration is used to boost dissolved oxygen for treatment and to improve taste, odor, and odor-related contaminants, as well as to aid in oxidizing certain dissolved metals by increasing contact with air.

Aeration is achieved through methods that maximize surface area and turbulence, such as diffusers emitting air bubbles, splash or cascade systems, or spraying water to increase air exposure.

This differs from filtration, which removes solids by passing water through a barrier; oxidation, which is a chemical reaction adding oxygen (not just contact with air); and sedimentation, which relies on gravity to settle suspended solids.
