A filtration device for the tangential filtration of a fluid to be treated is provided to correct the drawbacks of previous designs of the device, reduce production cost, obtain a limited size, and maintain a good filtration flow. A device for the tangential filtration of a fluid intended to be treated and divided into a filtrate and a residual liquid comprises at least one inlet(E) for the fluid to be treated, at least one outlet(S) for removal of the residual liquid, and a series of tubular filtration elements(3) lying in parallel to one another and passing through a positioning plate(4) in such a manner that the filtration elements are sealed at each of their ends, where the filtration elements have at least one outlet(7) for the filtrate, which is connected to a filtrate collection receptacle(6), a first connection chamber(11) into which one ends of the filtration elements are opened, and in which separation means are sealed and contacted with the adjacent positioning plate, and a second connection chamber(12) which provides a transport path for the fluid to be treated, between the filtration elements of a first series and a second series, and into which the other ends of the filtration elements are opened, wherein the separation means comprise a turbine(23) of a circulation pump, a drive shaft(25) put on the outside of the first connection chamber connected to a drive motor(26), and a connection path(24) formed between a second volume(V2) and a first volume(V1), and wherein the input for the fluid to be treated is opened into the first connection chamber of the outer case between the turbine of the circulation pump and the filtration elements of the series forming a return circulation of a circulation loop.
