    Abstract: The present invention relates to a process for dewatering oil sand tailing muds, comprising: (a) adding a flocculant into oil sand tailing muds and mixing the flocculant and the tailing muds; (b) filtering the flocculated tailing muds using a dynamic filtration system, wherein in step (b) a pressure difference is applied over the filter and wherein the dynamic filtration system comprises a means for producing a dynamic action by which the filter cake is continuously or intermittently moved, deformed and/or broken, the filter cake being the solidified material that sets on the filter during filtration. The process is useful for dewatering oil sand tailing muds from tailing ponds, such as those produced in the Athabasca Oil Fields in Canada.
