Ion Exchange
Ion Exchange is a common purification method used in many industries to clean water and other liquids by removing unwanted substances. Think of it like a water filter, but at an industrial scale. Companies use this process to produce clean water for drinking, manufacturing, and special industrial needs. It's similar to how a water softener works in homes, but on a much bigger scale for factories and treatment plants. When you see this term in resumes, it usually means the person has experience with water treatment, purification systems, or industrial cleaning processes.
