Abstract

A numerical method is presented to obtain approximate solutions to problems arising from sedimentation models. These processes are widely utilized in minery for recovering water from suspensions coming out of flotation processes. The main idea is to apply a multiresolution method to the existing schemes developed by B\"urger et al. [2, 3, 4] and to observe the good performance of the multiresolution strategy when applied to these kind of problems. We obtain high rates of memory compression without affecting the quality of the solution.
