The invention relates to a filtration system for filtering a fluid containing solid particles. The filtration system comprising a deformable wall defining a chamber interior to the wall, and a tubular shaped membrane arranged in the chamber. Further, the system is arranged for periodically deforming the chamber wall inwardly and outwardly, respectively, for filtering a fluid that is present in the chamber, exterior to the membrane.

The filtration system according to claim 1, wherein the deformable walls include respective flexible sleeves. 6. The filtration system according to claim 1, further including a respective heating element for heating the fluid. 7. The filtration system according to claim 1, comprising a multiple number of said tubular shaped membranes arranged in each chamber. 8. A method of filtering a fluid containing solid particles, comprising the steps of: providing a multiple number of chambers arranged in series, the chambers being defined interior to respective deformable walls, wherein respective tubular shaped membranes are arranged in the chambers and are connected in series, the tubular shaped membranes having radial exterior surfaces and respective fluid permeable tubular shaped structures arranged on the radial exterior surfaces and defining radial minimum positions of the deformable walls that are greater than respective radial exterior surface positions of the tubular shaped membranes, wherein the fluid permeable tubular shaped structures have sufficient stiffness to prevent the deformable walls from moving inwardly beyond the respective radial minimum positions,providing a multiple number of intermediate chamber members arranged in series between the chambers, further providing corresponding intermediate tubular shaped membranes arranged in series between the tubular shaped membranes, andperiodically deforming the deformable walls inwardly and outwardly, respectively, between radial outward positions and radial inward positions that are close to the respective radial exterior surfaces of the tubular shaped membranes, for filtering the fluid that is present in the chambers, exterior to the respective tubular shaped membranes,wherein the deformable walls are deformed in a peristaltic movement by radially symmetrical contraction and relaxation of the deformable walls inwardly and outwardly, in a radial direction with respect to respective symmetry axes of the chambers, propagating as a wave along said respective symmetry axes, thereby PROPELLING THE FLUID CONTAINING THE SOLID PARTICLES THAT IS PRESENT IN THE CHAMBERS, IN A CROSS FLOW OR TANGENTIAL FLOW, EXTERIOR TO SAID RADIAL EXTERIOR SURFACES OF THE TUBULAR SHAPED MEMBRANES, andwherein the chambers and the intermediate chamber members form a closed loop and wherein the tubular shaped membranes and the intermediate tubular shaped membranes form a closed loop.
