Continuous sedimentation

Sedimentation is a common industrial process for separating particles from a liquid by using gravity. Continuous sedimentation is performed under continuous in- and outflows of a large tank. The process can be found in most wastewater treatment plants and in the chemical, mining, pulp-and-paper and food industries. It is known for its nonlinear behaviour and there is a great need for reliable simulation tools and control strategies. Despite simplifying assumptions, the conservation of mass leads to a nonlinear partial differential equation (PDE) with space-discontinuous coefficients. There is also a need for developing methods of estimation of constitutive assumptions, which leads to inverse problems.

Stefan Diehl in the group has been working on this problem for a long time and produced results within both pure mathematics and the water, control and chemical engineering fields. For example, he has published the first advanced regulator for the PDE model process.
