Abstract
A dynamic model of the settling process in the secondary settler of a wastewater treatment plant is given by a nonlinear scalar conservation law for the sludge concentration under the form of a partial differen tial equation (PDE). Theoretical results on stationary solutions are f ound to be related with the limiting flux theory, allowing new insight s into this latter theory, especially when the settler is overloaded.
