Centrifuge
A Centrifuge is an important piece of equipment used in water treatment facilities to separate different materials from water and other liquids through spinning. Think of it like a super-powered washing machine's spin cycle - it spins materials very fast to separate heavier and lighter components. In water treatment, this helps remove solids from liquids, making water cleaner. When you see this term in resumes, it usually refers to experience with operating, maintaining, or supervising equipment that handles water purification and waste treatment processes.
