Context & Assumptions

The critical particle diameter defines the threshold at which solids are captured by gravity-driven separation processes like clarifiers or grit chambers. This parameter is essential for sizing equipment to ensure specific removal efficiencies and protecting downstream components from abrasive or clogging particles.
