Aeration
Aeration is a fundamental process in water treatment where air is added to water to improve its quality. Think of it like giving water a breath of fresh air. This process helps remove unwanted gases, adds beneficial oxygen, and helps break down certain contaminants. It's similar to how a fish tank bubbler works, but on a much larger scale for treating drinking water, wastewater, or industrial water. When you see this term in resumes, it usually refers to experience with managing or operating these systems that help clean and purify water.
