Abstract
In this work, it has been shown that an eccentric location of rotating membranes in a cylindrical tank has a positive effect regarding wall shear stresses compared to a concentric location. The study is made with CFD by use of a model that in a former study has been validated for a comparable setup. It has been shown that the rotation speed can be reduced with 33% to keep the same limiting flux with an eccentric location. As result of this, the energy consumption for the fouling mitigation can be lowered with 36% per m3 of treated wastewater if the system is operated at limiting flux.
