What is lost when aeration of water occurs?

When aeration of water occurs, soluble nutrients are often lost. Aeration involves introducing air into water, usually to increase oxygen levels, which can indeed lead to the elimination of certain dissolved substances. This process can enhance the natural biological processes that break down organic matter. During aeration, some soluble nutrients may escape into the atmosphere or can be modified as microbial activity increases, leading to changes in chemical composition.

While increasing oxygen levels is a direct effect of aeration, it is not lost; rather, the procedure aims to enhance these levels. Similarly, aeration typically helps maintain temperature stability by promoting evaporation, and it can also aid in the breakdown of organic pollutants. Hence, while organic pollutants may be affected by the process, it is the soluble nutrients that are most directly lost during aeration due to their propensity to either volatilize or be transformed by microbial action.
