The literature provides a comprehensive collection of equations to estimate the
terminal settling velocity of single solid particles in a liquid system. The settling velocity for perfectly round spheres can accurately be calculated. In the contrary for natural imperfect particles the experimentally measured settling velocity deviates considerably compared the calculated value. In drinking water treatment processes natural particles are frequently applied in up flow fluidisation processes and in addition sedimentation processes are applied to clarify water and to concentrate solids.
