The material balances and clarification rates of a lamella settler can be obtained from the particle size distribution and density of the solid, the liquid density and viscosity, the desired solids concentration in the overhead product, and the feed and underflow solids concentration, using an algorithm based upon a simple geometric model. The method was validated using concentrated suspensions (up to 20 vol % solids) of four different feed particle size distributions of hydrargillite (aluminum hydroxide) in water. Most of the data were obtained in a 60-cm-long settler with 1-cm plate separation inclined at 60/sup 0/ to the horizontal in ''open bottom'' and ''normal'' configurations. The hydrodynamics of tube settlers are more complex and the algorithm is not applicable.
