Webb1 maj 2009 · Sludge settling velocity is an important indicator to describe the performance of sludge settling which influences effluent quality of a secondary settling tank (SST). … For settling particles that are considered individually, i.e. dilute particle solutions, there are two main forces enacting upon any particle. The primary force is an applied force, such as gravity, and a drag force that is due to the motion of the particle through the fluid. The applied force is usually not affected by the particle's velocity, whereas the drag force is a function of the particle vel…
