In a wastewater treatment plant, particles (activated sludge) are separated from the liquid in a process called continuous sedimentation. This process is of crucial importance when purifying water in a wastewater treatment plant. This report will focus on a special case of sedimentation, namely batch sedimentation, which means that no flux into or out from the sedimentation tank are present. The g
