The deaeration of water is important for preventing corrosion in pipes.
Deaeration → It is formed from "de-" (meaning removal or reversal) and "aer" (from Latin "aer" meaning air) and "-ation" (meaning the process of). The word describes the process of removing air from a substance or environment.
Think of 'removing air' ('de-' means removal and 'aer' means air) — that's what deaeration means.
