Chlorination
Chlorination is a common water treatment method where chlorine is added to water to kill harmful bacteria and make it safe for drinking or other uses. It's like adding a cleaning agent to water, but in carefully controlled amounts. This process is used in many places including public water systems, swimming pools, and industrial facilities. When you see this term on a resume, it usually means the person has experience with water safety and purification methods. Similar terms you might see are "water disinfection" or "water treatment."
