Consideration of sludge rheology is very important for a proper solids transport and to obtain the necessary settler capacity. Although a true yield stress does not exist, large apparent viscosities at low shear rates inhibit an efficient sludge transport. Research indicates that the dimensionless ratio of gravity to viscous forces is an important operational parameter towards settler capacity. To improve solids transport scraper mechanisms are utilized that introduce extra shear to (i) overcome the pseudo-yield stress and (ii) liquefy the sludge.
