Backwash
Backwash is an essential cleaning process in water treatment facilities where water is pushed backward through filters to remove collected dirt and debris. Think of it like cleaning a coffee filter by running water in reverse. This process keeps water treatment systems running efficiently and ensures clean water delivery. When reading resumes, you might see this term used to describe experience with maintaining filters, operating treatment equipment, or managing water quality processes. It's a fundamental skill for water treatment operators and similar roles.
