    [0001] The present invention relates to the technical field of tangential flow separation elements of a fluid medium to be treated into a filtrate and a retentate, commonly called filtration membranes. Separation processes using membranes are used in many sectors, particularly in the environment for the production of drinking water and the treatment of industrial effluents, in the chemical, petrochemical, pharmaceutical, food and beverage industries. biotechnology. A membrane constitutes a selective barrier and makes it possible, under the action of a transfer force, to pass or stop certain components of the medium to be treated. The passage or the stop of the components results from their size compared to the size of the pores of the membrane which then behaves like a filter. Depending on the pore size, these techniques are called microfiltration, ultrafiltration or nanofiltration.
    [0002] There are membranes of natures, structures and different textures. For example, ceramic membranes. They are, in general, constituted by a porous support which ensures the mechanical strength of the membrane and also gives the shape and therefore determines the filtering surface of the membrane. On this support, one or more layers of a few microns thick ensuring the separation and said separating layers, filter layers, separation layers or active layers, are deposited. During the separation, the transfer of the filtered fluid is through the separator layer, and then this fluid flows into the porous texture of the support to point toward the outer wall of the porous support. This part of the fluid to be treated having passed through the separation layer and the porous support is called permeate or filtrate and is recovered by a collection chamber or peripheral space surrounding the membrane and defined by a housing and support plates of the membranes. The other part is called retentate and is most often reinjected into the fluid to be treated upstream of the membrane, thanks to a circulation loop. Typically, the carrier is first made to the desired shape by extrusion, then sintered at a temperature and for a time sufficient to provide the required strength, while retaining in the resulting ceramic the desired open and interconnected porous texture. . This process makes it necessary to obtain one or more rectilinear channels within which the separating layer or layers are then deposited and sintered. The supports are traditionally tubular and have one or more rectilinear channels arranged parallel to the central axis of the support. In general, such membranes are used in a casing to form a filtration module which is therefore constituted by a metal shell, most often cylindrical, which is equipped at its ends with a support plate in which provided holes for receiving the ends of the filter elements. Thus, to form a filtration module, the filter elements are positioned inside the housing extending parallel to each other. The filter elements are sealingly mounted at each of their ends on the support plate by means of gaskets. By casing is more specifically meant the assembly formed by a ferrule, which is a generally cylindrical metal casing, equipped at each of its ends with a plate, more specifically called a head plate, in which holes are arranged to receive and position the ends of the filter elements in parallel in the ferrule. The seal between the filter elements and the head plate is achieved with a single seal or several individual seals. The industrial modules of the prior art in fact comprise two types of joints, namely the single seal and the individual seal. The single seal consists of sealing all the separation elements present in a housing from a single piece perforated with as many passages as separating elements. These are arranged in parallel inside the housing and their positioning is obtained from the head plate which comprises a number of passages equal to the number of filter elements. These slightly exceed the head plate, a distance of the order of magnitude of the thickness of the joint 3036628. Above the seal, a counterplate is arranged for the purpose of compressing the latter by means of clamping nuts. This counterplate has passages whose axes coincide with those of the head plate. The diameter of these passages is slightly less than the outer diameter of the filter element. The main parameters involved in the design of this joint are its thickness, defined by the part of the filter element that penetrates inside the joint and its hardness which, defined from the Shore hardness, participates in the joint. crushing of the seal during the clamping phase of the counterplate. The combination of the hardness and the thickness makes it possible to define a crush on which the tightness will depend. The individual seal is placed around each filter element. It consists of a skirt that surrounds part of the ends of these. The outer portion of this skirt may be cylindrical or conical.
    [0003] This skirt is extended by an upper part which partly covers the end of the filter element. This portion is disposed at the periphery of the end of the separating element and its internal diameter is determined not to close the traffic channels. As before, the housing comprises a head plate having as many passages as filtration elements. The shape and dimensions of these passages are determined to receive the skirt of the seal (cylinder or cone), thus avoiding any contact between the filter element and the metal of the head plate. As for the upper part of the seal it is housed in countersinks made in the counterplate, the depth of these countersinks being lower than the upper part of the seal. Three main parameters contribute to the realization of these individual joints: the shape of the skirt, the height of the upper part and the Shore hardness of the joint. The combination of these three parameters makes it possible to define, on the one hand, a crush on which the sealing will depend and, on the other hand, the protection of the part of the filtration element which passes through the head plate. Whatever the type of joint, single or individual, their achievements are carried out by plastics operations that require the manufacture of 3036628 4 expensive injection molds whose damping significantly contributes to the cost price of the joint. Since the internal volume of a separating element is defined and limited by its external dimensions and the area of the filtering surface being proportional to the number of channels, it has been found that the area of the filtering surfaces of the filtration membranes is collide with a ceiling and, as a result, have limited performance in terms of throughput. Historically and chronologically, single-channel cylindrical tubular separating elements have appeared on the market, followed by multichannel tubular separating elements. The first multichannel separation elements, one of whose interests, in addition to increasing the total surface area of the filtering surface, lies in obtaining channels of small hydraulic diameters without any risk of fragility for the separating element, consisted exclusively of 15 channels of circular straight sections. The next generation abandoned the circular channels in order to better occupy the internal volume of the tube and increase its filtering surface which had the effect of increasing the compactness expressed in m 2 / m 3 in the housings and also to increase the possibilities of turbulence; this compactness, expressed in m2 / m3, corresponding to the ratio of the sum of the filtering surfaces of the filtration elements divided by the internal volume of the housing in which they are installed. It is known that the compactness of the housings in which single-channel or multichannel separation elements are installed is limited, for a casing of given inside diameter and for separating elements having a given filtering surface, by the distance D between each of these elements. separation elements, which distance is dependent on the thickness of the joints used and the requirements of mechanical strength of the head plates.
    [0004] Furthermore, regardless of the type of seal, single or individual, the skirt which covers the outer part of the filter element and provides sealing between the metal and the filter element is extended by a sole. common in the case of the single joint or by an individual sole in the case of the individual joint. The thickness of this skirt and the fabric between two passages define this distance D which depends directly on the number of filter elements inside the housing. This fabric is defined to allow the mechanical strength of the housing such as a resistance to an internal pressure of 10 bar. By way of example, the table below gives the number of separating elements and the number of individual joints for three industrial casings. Industrial configuration of prior art DN200 213mm 37 74 DN350 349mm 99 198 DN100 Housing inner diameter 110mm Number of filtration elements in the housing 7 Number of individual specific seals 14 The present invention aims to remedy the drawbacks of the prior art providing a novel monoblock separation system for achieving tangential flow molecular and / or particulate separation of a fluid medium, and designed to improve compactness i.e. ratio of filter surface to total volume internal casing, (ratio expressed in m2 / m3), this new system to further simplify the modules by reducing the number of joints required and removing the obligation of the head plates. With such a one-piece system according to the invention, the compactness, expressed in m2 / m3 in the housings, is increased, with equal hydraulic diameter, by a factor of at least 1.5 compared to the prior art. and the use of known single-channel and multichannel separation elements. To achieve such compactness, the invention relates to a monoblock separation system for obtaining a molecular and / or particulate separation of a fluid medium to be treated into a filtrate and a retentate, this system comprising a structure of at least two columns rigid porous made of the same material, positioned next to one another to define outside of their outer walls, a recovery volume of the filtrate, each column having internally at least one open structure for circulation fluid medium, opening at one end of this porous column for the inlet of the fluid medium to be treated and at the other end for the outlet of the retentate, characterized in that said porous columns are joined together to the one and the other of their ends with the aid of an inlet sole and an outlet sole, said insoles being not reported on the s porous columns to form together said monobloc structure.
    [0005] Thus, the object of the invention being to propose a separation module implementing a one-piece separation system according to the invention by optimizing the distance between the porous columns and the material thickness of the porous columns, it can an increased compactness expressed in m2 / m3, with equal hydraulic diameter, compared to the known non-monochannel and multichannel separation elements is obtained.

    [0011] Figures 7A to 7E illustrate the compacities (in ordinate and m2 / m3) obtained for separation systems according to the invention mounted in housings DN100 and DN350, as a function of the distance d (in abscissa and in FIG. mm) between the porous columns respectively provided with a channel, 7, 23, 39 and 93 channels and respectively for a hydraulic diameter equal to 6mm, 6mm, 3,5mm, 2,5mm and 1,6mm. As a preliminary, some definitions of terms used in the scope of the invention will be given. By average pore diameter is meant the value d50 of a volume distribution for which 50% of the total pore volume corresponds to the pore volume of diameter less than this d50.The volume distribution is the curve (analytic function) representing the 10 frequencies of pore volumes as a function of their diameter. The d50 corresponds to the median separating into two equal parts, the area under the frequency curve obtained by mercury penetration, for average pore diameters greater than or equal to 4 nrn or by adsorption of gas, and especially of N2, when the average pore diameters are less than 4 nm, these two techniques being used as references in the context of the invention for measuring the average pore diameter. In particular, it will be possible to use the techniques described in: - the standard 150 15901-1: 2005, as regards the mercury penetration measurement technique; The standards 150 15901-2: 2006 and 150 15901-3: 2007, as regards the gas adsorption measurement technique. The object of the invention is the separation systems for obtaining a molecular and / or particulate separation of a fluid medium by tangential filtration, commonly called filtration membranes. In a general manner and as illustrated in the figures, such a separation system 1 comprises a rigid structure 2 monolithic or monobloc. In the context of the invention, a monobloc structure is defined as being made of a single piece, homogeneous and continuous throughout, seamless or non-exogenous contributions. In other words, no constitutive part 30 of this monobloc structure is reported, that is to say that this one-piece structure is manufactured in a single operation so that this monobloc structure is directly usable for the deposition of separating layers or requires at most a heat treatment. According to the invention, the one-piece structure 2 comprises at least two and in the example illustrated in FIG. 1, three rigid porous columns 3 made of the same porous material, positioned one beside the other to delimit outside their outer walls, a peripheral space 4 for recovering the filtrate. Each porous column 3 forms a rigid porous support having a generally elongate shape extending from a first end 31 to a second end 32 opposite the first end. Each porous column 3 internally comprises at least one open structure 5 for the circulation of the fluid medium to be treated, opening at the first end 31 of this porous column for the entry of the fluid medium to be treated and at the second end 32 of this porous column for the output of the retentate. This open structure 5 which in the illustrated example is in the form of a channel, corresponds to a void space for the circulation of the fluid medium that is to say to a zone of the porous column 3 having no porous material. The portion of each porous column 3 delimiting the open structure 20 or channel 5 has a surface covered by at least one separating layer C, intended to be in contact with the fluid medium to be treated, circulating inside the open structure 5. A portion of the fluid medium passes through the separating layer C and the porous material of the porous columns 3, so that this treated portion of the fluid, called filtrate or permeate, flows through the outer wall 3a of each porous column. The filtrate is recovered in the peripheral space 4 of the porous structure by any appropriate means. Each porous column 3 thus has a peripheral wall of thickness e between the open structure 5 and the outer wall 3a.
    [0012] According to the invention, the porous columns 3 are secured to each other at least at their first adjacent ends, with the aid of an inlet plate 7 and at their neighboring second ends, with the aid of a 3036628 12 outsole 8. Each sole 7, 8 provides a mechanical assembly connection between the porous columns 3 with the input plate 7 ensuring the connection of the rigid porous columns 3 at their first ends 31 and with the sole of output 8 ensuring the connection of the porous rigid columns at their second ends 32. In accordance with the invention, the soles 7, 8 are not reported on the porous columns to form together said monobloc structure. Indeed, the porous columns 3 and the flanges 7, 8 are manufactured in a single operation so that the monoblock structure 2 thus obtained is directly usable for the deposition of the separation layers C for the fluid medium to be treated or requires at most a heat treatment. Each sole 7, 8 has a so-called inner face 71, 81 facing towards and in contact with the peripheral space 4 of the porous structure and an outer face respectively 72, facing towards and in contact with the fluid medium to be treated and 82 turned to and in contact with the retentate. The inlet and outlet soles 7, 8 which have a circumference respectively 73, 83 of variable thickness depending on the desired strength, have a cross section adapted to allow its mounting in a housing as it will be better understood in the following the description. In the example illustrated in the drawings, the soles 7, 8 have a circular cross section but it is clear that the cross section of these soles may be different that is to say non-circular. According to one characteristic of the invention, the porous columns 3 are joined to each other also by means of at least one connecting bridge 9 making it possible to stiffen the porous columns 3 with each other while allowing a constant distance to be maintained between the porous columns 3. Thus, the porous columns 3 are separated from each other by a distance d. These connecting bridges 9 are made locally in all appropriate forms, being distributed preferably evenly between the soles. These connecting bridges 9 are preferably made of the same material as the porous columns. Of course, these connecting bridges 9 may also be made with a material different from the porous columns and the flanges. The porous columns 3 and the inlet plates 7 and 8 or even even, the connecting bridges 9 form a monobloc structure. Such monobloc structures 2 which can not be made by traditional extrusion techniques can be preferably carried out by additive techniques such as those described for example by the patent application FR 3,006,606. According to an additive method of manufacture, it is considered that the soles and columns are said to be unreported if the manufacture allows the shaping of the soles 7, 8 and porous columns 3, so that the monoblock structure 2 thus formed is directly usable for the deposit layers or requires at most a heat treatment. According to an additive manufacturing method, the whole monoblock structure being constructed by superposition of 15 elementary strata bonded together by spraying a liquid into fine droplets or by a supply of energy, a first consolidation heat treatment is in effect indispensable in the first case; the energy-material interaction is normally sufficient to lead to either sintering or melting / solidification of the material in the second case.
    [0013] This heat treatment is particularly indispensable when the localized liquid supply is made with microdroplets created using a piezoelectric system, possibly charged and directed in an electrostatic field; the liquid being a binder or an activating agent of the binder previously added to the ceramic powder.
    [0014] Such monoblock structures 2 can also be produced for example by the casting technique which requires an operation of producing the mold, preparing the casting suspension, casting itself, drying, demolding and heat treatment to obtain the porosity and the solidity of the monobloc structure.
    [0015] For such monoblock structures 2, the porous columns 3 exhibit a continuous porous texture over the entire volume of the porous column. This porous texture is characterized by the average pore diameter deduced from their distribution as measured by mercury penetration porometry. The porous texture of the porous columns 3 is opened and forms a network of interconnected pores, which allows the fluid filtered by the filter separation layer 5, to pass through the porous structure and to be recovered by the peripheral space 4 of the structure porous. It is customary to measure the water permeability of the porous structure to qualify the hydraulic resistance of the structure, which at the same time makes it possible to confirm the interconnection of the porous texture. Indeed, in a porous medium, the stationary flow of an incompressible viscous fluid is governed by Darcy's law. The velocity of the fluid is proportional to the gradient of the pressure and inversely proportional to the dynamic viscosity of the fluid, via a characteristic parameter called permeability which can be measured, for example, according to the French standard NF X 45-101 of December 1996.
    [0016] Most often, the porous columns 3 are made of a non-metallic inorganic material. Preferably, the porous columns 3 consist of a ceramic chosen from oxides, nitrides, carbides or other ceramic materials and mixtures thereof, and in particular from titanium oxide, alumina, zirconia and their mixture, titanium nitride, aluminum nitride, boron nitride, and silicon carbide optionally mixed with another ceramic material. It should be noted that the porous structure can also be made of a purely metallic organic or inorganic material. For example, the porous columns 3 are made of a pure metal such as aluminum, zinc, copper, titanium or an alloy of several of these metals or stainless steels. For example, the material constituting the porous columns 3 has an average pore diameter in the range of 1 μm to 100 μm.
    [0017] According to a preferred embodiment, the porous columns 3 and the flanges 7, 8 are made of the same material for an identity and continuity of porous material and texture between the flanges and the porous columns 3. According to this example the porosity of the constituent material of the porous columns 3 and the flanges 7, 8 is identical. It should be noted that it is possible to provide the soles 7, 8 and the porous columns 3 with the same material, considering that the material of the soles has a porosity different from the material of the porous columns and taking into account the fact that of course, the material of the soles is not attached to the porous columns 3. According to another embodiment variant, the soles 7, 8 are made of the same material as the porous columns 3, considering that the material of the soles 7, 8 which is not reported, has zero porosity. According to this variant embodiment, only the porous columns 3 allow the fluid filtered by the filtration separator layer, to pass through the porous structure and to be recovered by the peripheral space 4 of the porous structure.
    [0018] According to an advantageous characteristic of embodiment of the invention, each soleplate 7, 8 is made in the form of a solid element to form a solid plate whose section includes all the sections of the porous columns 3. The soles 7, 8 close and the peripheral space 4 of the porous structure, to thereby confine the filtrate. Each sole 7, 8 has an outer face 72, 82 in contact respectively with the fluid medium to be treated and the retentate, these outer faces 72, 82 being sealed to prevent the fluid medium to be treated and the retentate penetrate the soles. The sealing of the outer faces 72, 82 of the flanges 7, 8 can be made in any appropriate manner. For example, the outer faces 72, 82 of the flanges 7, 8 are sealed by densification to a value equal to or very close to the intrinsic density of the material or by impregnation or deposition of a material added other than that of the sole. Thus, as is more particularly apparent from Figs. 3 and 3A, the separation system 1 according to the invention is intended to be implemented in a separation module 11 of all types known per se. In a conventional manner, the separation module 11 comprises a casing 12 of tubular form in which one or more separation systems I.sub.1 are mounted.
    [0019] For this purpose, the separation module 11 is mounted in such a way that the inlet and outlet soles 7 and 8 are positioned at the ends of the casing 12. These inlet and outlet soles 7 are mounted in sealing means on the housing 12 with seals 14. These 5 seals 14 are mounted in any appropriate manner on the housing either directly at the ends of the housing or in holes in a support plate reported and fixed at the ends of the housing. The porous columns 3 are thus positioned inside the casing 12 which is closed by the flanges 7, 8 and the sealing seals 14 possibly associated with support plates. The housing 12 thus delimits with the outer wall 3a porous columns 3 and the inner faces 71, 81 of the flanges, the peripheral space 4 for recovering the filtrate. The filtrate thus confined in the casing 12 is evacuated by any appropriate means, from an outlet 15 provided on the casing 12.
    [0020] In the example illustrated in FIGS. 3 and 3A, the separation device 11 comprises a single separation system 1 comprising a number of porous columns 3 chosen to obtain the desired filtering surface. Of course, the separation device 11 may comprise several separation systems 1 according to the invention. In this case, each separation system 1 is sealingly mounted in the housing 12 by means of the flanges 7, 8 provided with seals 14. As can be seen from the foregoing description, the fluid medium enters and respectively, the inlet 7 and outlet 8 soles of the one-piece structure 2 come out of separate openings forming the open structure 5 which in the example illustrated in FIG. 1, has three channels. The filtering separating layer C which covers the walls of each channel 5 ensures the filtration of the fluid medium to be treated. The filter separating layers C, by definition, must have an average pore diameter smaller than that of the porous columns 2. The separating layers 30 delimit the surface of the tangential flow separation element intended to be in contact with the fluid to be treated and on which the fluid to be treated will flow.
    [0021] A tangential flow separation element of the state of the prior art generally has a length of 1 meter to 1.5 meters. The section of a tangential flow separation element most often has a surface area of 0.8 cm 2 to 14 cm 2.
    [0022] In the context of the present invention, the one-piece columnar structure separation elements may have a length of a few centimeters to several meters, preferably between 5 cm and 5 m. The section of a monoblock columnar structure separating element depending on the number of columns and the distance between these columns may vary from a few centimeters to several meters. The thicknesses of the filter separating layers typically vary between 1 and 100 μm in thickness. Of course, in the context of the present invention, to ensure its separation function, and serve as an active layer, the separator layers 15 have an average pore diameter smaller than the average pore diameter of the porous column. Most often, the average pore diameter of the filter separator layers is at least 3-fold lower, and preferably at least 5-fold higher than that of the porous column.
    [0023] The notions of microfiltration, ultrafiltration and nanofiltration separator layers are well known to those skilled in the art. It is generally accepted that: the microfiltration separator layers have an average pore diameter of between 0.1 and 20; the ultrafiltration separator layers have an average pore diameter of 0.01 to 0.1 μm; the nanofiltration separation layers have an average pore diameter of between 0.5 and 10 nm. It is possible for this micro or ultrafiltration layer to be deposited directly on the porous column (in the case of a monolayer separation layer), or on an intermediate layer with a smaller average pore diameter, itself deposited directly on the porous column. the porous column.
    [0024] The separating layer may, for example, be based on or consisting exclusively of one or more metal oxides, carbide or nitride or other ceramics. In particular, the separation layer will be based on, or consist exclusively of, TiO 2, Al 2 O 3 and ZrO 2, alone or as a mixture. In the example illustrated in FIG. 1, each porous column 3 advantageously has a single channel. Of course, it may be envisaged to make several channels in each porous column. In the case where the porous support comprises several channels, it can be provided to arrange the channels 5 to create within each porous column, at least two circulation circuits for the fluid medium, not interconnected between them, between the sides inlet and outlet of the porous column. According to this exemplary embodiment, each channel 3 extends from the inlet to the outlet of the porous column without being connected to another channel. FIGS. 4, 4A and 4B illustrate such an exemplary embodiment in which each porous column 3 has 7 channels 5 arranged independently of each other in the input plate 7 to the outlet plate 8. Of course, the number of channels per porous column may be different from the example shown. According to another embodiment, it can be provided to arrange the channels 5 to create within each porous column, at least two circulation circuits for the fluid medium, interconnected between them, between the input and output sides of the porous column. During its course within these circuits, the fluid medium is able to meet at least one bifurcation or separation leading the fluid medium to separate into several parts (at least two) to follow different paths, and / or a junction leading to the joining of several parts of the fluid medium (at least two) from different paths. Thus, the circulation circuits of the network communicate with each other by crossings or interconnections arranged within the porous column. An advantage of the object of the invention is to make it possible to improve the compactness of the separation systems when they are mounted in a housing. Table 1 below gives the compacities in m2 / m3 for different separation membranes mounted in a cylindrical housing 303 6 62 8 19 DN 200 of 213 mm internal diameter. As indicated in this table, the separation membranes have either circular or hexagonal sections, having a specified number of channels of circular section or non-circular section, and a hydraulic diameter Dh.

    [0025] 7A illustrates the compacities in m2 / m3 obtained for separation systems 1 according to the invention comprising circular columns of circular section with a single central channel all identical with an outside diameter of 10 mm and a thickness e equal to 2 mm, the inner circular channel then having a hydraulic diameter Dh = 6 mm, mounted in housings DN100 and DN200 defined by their inside diameters, each rigid structure 2, arranged according to the description of the invention, ending in end flanges 7 and 8 connected to the housing through a single seal. These compactness values are as a function of the distance d (in abscissa and in mm), reported by decreasing values.pAn The maximum distance d between the columns of 2 mm corresponds to the distance which, in the prior art, separates the elements 10 mm outer diameter filtration when installed in such industrial housings.
    [0026] When this distance decreases, which a separation system object of the present invention makes it possible to do, the compactness of the casings increases.

Figs.

These compactnesses are compared with the reference compactness (horizontal line) of an industrial configuration of the prior art composed of multi-channel membranes with an external diameter of 25 mm, with an equivalent hydraulic diameter. When the porous columns have a single channel, compared to the prior art industrial configurations using circular membranes of 25mm to multichannel outer diameter and equivalent hydraulic diameters, the separation systems according to the invention allow, depending on the value of the distance d between the porous columns 3, higher compacities up to a certain limit value of the hydraulic diameter Oh close to 2.3mm.

This behavior is explained by the fact that the thickness of the columns can not be exaggeratedly diminished (here the minimum thickness is considered to be reasonably between 0.8 and 1 mm). Figs.
    [0029] 6A to 6C illustrate the compacities (in ordinate and in m2 / m3) obtained with the separation systems I. according to the invention mounted in a housing DN200 as a function of the distance d (in abscissa and in mm) reported by values increasing, between the porous columns 3 provided with a single channel or several channels in comparison with an industrial configuration of the prior art of equivalent hydraulic diameter taken as reference (horizontal line).

In general, when the porous columns have several channels, compared to the prior art industrial configurations using circular membranes with multichannels and equivalent hydraulic diameters, the separation systems according to the invention allow ever higher compactness as soon as possible. when the distance d is less than 8.1mnn.

Another advantage of the invention relates to the simplification for the mounting of such a separation system 1 according to the invention, in a separation module 11 made in any known manner. Indeed, the presence of the inlet and outlet soles which ensure the assembly of several porous columns makes it possible to facilitate the sealing to be achieved with the casing and in particular to limit the number of seals to be used with respect to known solutions.
    [0046] As more particularly apparent from FIG. 3, such a separation system 1 is mounted at the ends of the casing 12 by means of the flanges 7, 8. For this purpose, a seal 14 is mounted on the periphery 73, 83 of the flanges 7, 8. two seals 14 are mounted by any appropriate means to the ends of the housing to allow closing the peripheral space 4 for recovering the filtrate which is discharged from the housing by an outlet 15 or by any known suitable means. In the example illustrated in FIG. 3, the separation device 11 comprises a single separation system 1 comprising a number of porous columns 3 chosen to obtain the desired filtering surface. Well understood, the separation device 11 may comprise several separation systems 1 according to the invention. In this case, each separation system 1 is sealingly mounted in the housing 12 using the flanges 7, 8 provided with seals 14.
    [0047] Thus, according to the invention, it is no longer necessary to use individual or single seals which are specific to the filter elements, and it may thus be advantageous to use non-specific seals (toric, square, lip ....) from the seal manufacturer's catalogs that provide the required seal between the permeate collection chamber and the upstream and downstream chambers of the module. According to a preferred variant of the invention, the porous columns 3 all have identical shapes. In the example illustrated in the figures, all the porous columns 3 have a cylindrical shape of circular section. Of course, it may be provided that the porous columns 3 have different shapes to each other. According to a preferred variant of the invention, the porous columns 3 are of cylindrical shape. The section of the porous columns 3 may be circular or other. According to a preferred variant of the invention, the porous columns 3 have identical transverse dimensions. In other words, the thickness e of the porous columns 3 is identical for all the porous columns 3. Of course, it may be provided that the porous columns 3 have different transverse dimensions. According to the example illustrated in FIG. 1, the porous columns 3 extend in a rectilinear manner while being positioned parallel to one another. It should be noted that the porous columns 3 may extend helically as illustrated in FIG. 2, making it possible to create a rotating flow for the fluid to be treated. According to this variant embodiment, each porous column is constructed by the rotation of a circular section or else around a central axis, this generating section remaining either perpendicular to the central helix (coil) or horizontal (torso column). or be vertical, ie parallel to the central axis (Saint-Gilles screw).
    [0048] According to another variant embodiment, the porous columns 3 are interwoven as illustrated in FIG. 2. The invention is not limited to the examples described and shown because various modifications can be made without departing from its scope. 5
