The element is disposed in a vessel receiving a fluid flow. The vessel wall is porous at least for a proportion of the fluid and bounds an inner chamber communicating through the vessel wall with a chamber outside the vessel. The element is in the shape of a plate or tube and is so devised that the porous wall either on its own or in combination with other similarly shaped elements to form a module, forms a turbulence generator particularly in the form of a static mixer for the fluid flow. The resulting turbulence on the wall of the elements ensures that the wall remains porous.
