Context & Assumptions

Gravity settling tanks are fundamental in process engineering for separating dispersed phases (particles, drops, or bubbles) from a continuous fluid. This design method ensures efficient particle removal by balancing the particle's terminal settling velocity against the fluid's superficial velocity. It is widely applied in various industries, including water treatment, oil-water separation, and chemical processing.
