Definitions
- the field of the invention is that of sorting fibers, in particular synthetic fibers.
- the invention relates to a device for sorting fibers by differentiated lateral movement of the fibers.
- the invention finds particular applications in the treatment of wastewater loaded with fibers, in particular synthetic fibers.
- the invention also finds applications in the field of biology, for the characterization of filaments derived from cytoskeletons, or the identification of pathogens.
- Wastewater treatment techniques in particular of the wastewater treatment plant type, are known from the prior art. Although these techniques make it possible to filter the majority of impurities contained in wastewater, they do not make it possible to filter the smallest waste, in particular microplastics.
- Microplastics which are defined as plastic particles less than 5 millimeters in size, are particularly harmful to the ecosystem due to their dispersion in rivers, lakes, seas and oceans, and ultimately their integration into the food chain of animals and humans.
- Synthetic fibers are found in wastewater, particularly following washing of synthetic clothing in the washing machine.
- the present invention aims to remedy all or part of the disadvantages of the state of the art cited above.
- the invention aims at a device for sorting fibers, in particular synthetic fibers, contained in a liquid loaded with fibers, the sorting device comprising a container extending in a substantially vertical direction and being adapted to contain the liquid, and a network of obstacles arranged in the container, the network of obstacles being configured so as to be able to be crossed by a fiber from an upper zone of the container towards a lower zone of the container, called recovery zone, under the effect of gravity, and the network of obstacles comprises a plurality of substantially parallel rods, extending substantially orthogonal to said substantially vertical direction, and in which the cross section of a rod is of shape triangular, and in which the orientation of a rod is such that a majority of the vertices of the triangular shape are closer to the upper zone of the container, than to the lower zone of the container, whereby the network of obstacles is configured to induce a lateral movement of said fiber differentiated according to the length of the fiber and/or the flexibility of the fiber, so as to sort fibers in the
- the sorting device is thus entirely passive, which allows the implementation of the device without requiring an external energy source.
- the vertical orientation of the container in use that is to say substantially parallel to the direction of the local gravitational field, makes it possible to ensure movement of the fibers in the container under the sole effect of gravity.
- the vertical orientation of the device therefore corresponds to a normal configuration of use of the device.
- sorting can be carried out in the device under the sole effect of gravity, and in particular in the absence of the effect of any active means to cause the fibers to cross the network of obstacles.
- the device makes it possible to filter a liquid loaded with fibers, as well as to sort the latter according to their type.
- the network of obstacles is in fact chosen so as to induce a lateral movement of the fibers which depends on their mechanical properties, that is to say which depends on the type of fiber, and here in particular on its length and/or or its flexibility.
- Sorting is carried out by the sole hydrodynamic interaction between the fibers and the obstacles of the obstacle network, immersed in the liquid.
- a liquid initially loaded with fibers poured into the container such as waste water loaded with synthetic fibers
- a rest time allowing the fibers to move towards the bottom of the container under the effect of their own weight.
- the fibers sorted according to their Mechanical properties can be recovered at the recovery zone.
- the sorted fibers can be revalorized, and the liquid previously loaded with fibers is filtered, and can for example be released into the environment without fear of microplastic pollution.
- the plurality of substantially parallel rods extending substantially orthogonal to said substantially vertical direction, form a network of obstacles in the manner of a fence, through which the fibers can move.
- the sorting device is particularly simple in design, which makes it both inexpensive and simple to maintain, and easily adaptable for different applications.
- Said triangular shape has rounded vertices.
- Said triangular shape is isosceles, and preferably equilateral.
- a base of said triangular shape is substantially parallel to a bottom of the container.
- the network of obstacles comprises a plurality of series of rods, arranged offset one above the other in said substantially vertical direction, so as to obtain a staggered arrangement of the rods in the substantially vertical direction .
- Such an arrangement has the effect of maximizing the probability of a fiber encountering an obstacle, and in particular several obstacles, during its movement through the obstacle network. As lateral movements can thus be combined, discrimination when exiting the network of obstacles is improved. In addition, such an arrangement favors fiber movements along diagonals of the sorting network, which reinforces the total lateral movement.
- the maximum dimension of the cross section of a stem is between 0.5 and 10 times the average length of the fibers intended to be sorted.
- Such a range of values represents a good compromise between the risk of fibers being blocked in the network, and the probability for a fiber to encounter a obstacle and being moved laterally.
- a maximum dimension of the cross section of a rod is between 1 and 3 times the average length of the fibers intended to be sorted may be preferred, and represents an ideal compromise.
- the invention also relates to a biological analysis installation comprising a sorting device as described above, for the characterization of biological fibers, in particular pathogens or cytoskeletons.
- the invention also relates to a wastewater treatment installation comprising a treatment circuit and a fiber sorting device, as described above, the device being arranged downstream of said treatment circuit.
- the invention also relates to the use of a device for sorting fibers, in particular synthetic fibers, contained in a liquid loaded with fibers, the sorting device comprising a container extending in a substantially vertical direction and being adapted to contain the liquid, and a network of obstacles arranged in the container, the network of obstacles being configured so as to be able to be crossed by a fiber from an upper zone of the container towards a lower zone of the container, called zone recovery, under the effect of gravity, the network of obstacles being configured to induce a lateral movement of said fiber differentiated according to its flexibility, to sort fibers in particular according to their flexibility by deposit at differentiated lateral positions in the zone of recovery.
- sorting can be performed based on the flexibility and length of the fiber, together determining a characteristic behavior of the fiber in the interacting liquid in the obstacle network.
- Sorting according to flexibility makes it possible to discriminate fibers according to their constituent material for example, unlike the known technique.
- sorting can be carried out under the sole effect of gravity, and in particular in the absence of the effect of any active means to cause the fibers to cross the network of obstacles.
- the obstacle network is chosen according to the fibers to be sorted, with the ratio between the length of the fibers and the maximum dimension of an obstacle of the obstacle network which is substantially equal to 1.
- the network of obstacles comprises a plurality of rods chosen according to the fibers to be sorted, with the maximum dimension of the cross section of a rod which is between 0.5 and 10 times the average length of the fibers intended to be sorted.
- the sorting of fibers is carried out so that the Reynolds number, characterizing the behavior of the liquid in the container, is less than 1, preferably less than 0.1.
- the device is used to sort fibers contained in a liquid loaded with fibers comprising water, in particular salt water.
- the device is configured in particular to be able to contain water, for example salty, intended to be treated.
- Water polluted with microplastic fibers is a type of liquid particularly likely to be filtered by the device.
- the device is used to pull fibers in a wastewater treatment facility or in a biological analysis facility.
- the invention also relates to a process for sorting fibers, in particular synthetic fibers, contained in a liquid loaded with fibers, according to their flexibility in particular, comprising the steps of:
- a sorting device comprising a container extending in a substantially vertical direction and being adapted to contain the liquid, and a network of obstacles arranged in the container, the network of obstacles being configured so as to be able to be crossed by a fiber from an upper zone of the container to a lower zone of the container, called the recovery zone, under the effect of gravity;
- the sorting process is passive, that is to say, it is enough to fill the container with liquid loaded with fibers, then let it rest, without external intervention and without intervention of an active element , so that fiber sorting can take place.
- the container can first be filled in whole or in part with liquid, in particular with liquid not loaded with fibers.
- the sorting can be carried out under the sole effect of gravity, and in particular in the absence of the effect of any active means to cause the fibers to cross the network of obstacles.
- FIG. 1 is a schematic representation of a sorting device according to a particular embodiment, in a sectional view.
- FIG. 2 is a detailed view of two obstacles of different types, in a cross section.
- FIG. 3 is a graph illustrating the lateral displacement of a fiber for different elasto-gravitational numbers Be.
- FIG. 4 is a graph illustrating the lateral displacement of a fiber for different ratios between maximum dimension of the obstacle and length of the fiber.
- FIG. 5 is a graph illustrating the lateral movement of a fiber for different shapes of obstacles in the obstacle network.
- FIG. 6 is a schematic representation of a wastewater treatment installation including a sorting device.
- Figure 1 schematically represents a sorting device 100 according to a possible embodiment, in a longitudinal sectional view.
- the sorting device 100 comprises a container, which is in particular a tank 110.
- the tank 110 is adapted to contain a liquid loaded with fibers 120, in particular synthetic fibers.
- a liquid can for example comprise water, and in particular a solute such as salt.
- the liquid may be silicone oil.
- the tank 1 10 comprises side walls 1 1 1, a bottom 1 12, and an opening 1 13 adapted to fill the tank 1 10 with a liquid.
- the tank 110 comprises an upper wall 114 provided with the opening 113.
- the opening 113 can however be made in a side wall 111.
- the tank 110 extends in a longitudinal direction between the bottom 112 and the upper wall 114.
- the height of the tank 1 10, defined as its dimension in the longitudinal direction, is here greater than its transverse dimensions.
- the tank 110 can also be wider than it is high, in other embodiment variants.
- the tank 1 10 can in particular have a rectangular base, although any other shape can also be suitable.
- the dimensions of a rectangular base of the tank 110 can be 40 centimeters by 60 centimeters. Its height is for example 80 centimeters.
- the sorting device 100 comprises a network of obstacles 130 arranged inside the tank 110.
- the network of obstacles 130 is configured to induce a differentiated lateral movement of the fibers 120, depending on their mechanical properties.
- the network of obstacles 130 extends between an upper zone 140 of the tank 110, and a lower zone 150, called recovery zone, of the tank 110, and can be crossed by a fiber 120 from the upper zone 140 to the lower zone 150.
- the network of obstacles 130 is arranged at a distance from the bottom 112, and at a distance from the upper wall 114.
- the network of obstacles 130 extends substantially from one side wall 111 to the other, being substantially parallel to the bottom 112.
- the obstacle network 130 includes a plurality of obstacles.
- the obstacles include rods 131, solid or hollow.
- the rods 131 are preferably rectilinear.
- the rods 131 extend substantially parallel to each other, in a transverse direction of the tank 110, which is in particular orthogonal to the longitudinal direction of the tank 110. In other words, the rods 131 are arranged substantially parallel to the bottom 112.
- the rods 131 can be arranged in a plurality of series 132 of rods, the series 132 being arranged offset one above the other in the longitudinal direction of tank 1 10.
- the network of obstacles 130 comprises between five and fifteen, preferably ten, series 132 of rods.
- each series 132 of rods comprises between five and ten rods 131.
- the distance d between two adjacent rods 131 belonging to two different series corresponds for example to between 1 and 2 times, preferably 1.5 times, the maximum dimension of the cross section of a rod 131.
- a cross section of a rod 131 is circular in shape.
- Such a configuration is shown on the right in Figure 2, which represents the cross sections of two variants of rods 131.
- a cross section of a rod 131 is polygonal in shape.
- the polygonal shape of a rod section 131 is a triangular shape.
- the triangular shape is isosceles, preferably equilateral.
- the polygonal shape of a rod section 131 has rounded or blunt vertices.
- a particularly preferred configuration is a rod section 131 of triangular shape, the vertices of which are rounded, as shown on the left in Figure 2.
- the triangular shape with rounded vertices is not limited to the representation made in Figure 2. Indeed, any shape of triangle going almost from a circle, to a “conventional” triangle, can be considered. In other words, the vertices of the triangular shape can be from slightly rounded to very strongly rounded.
- the orientation of a rod 131 is preferably such that a majority of the vertices of the triangular shape are closer to the upper zone 140 of the tank 1 10, that is to say of the upper wall 114, that of the lower zone 150 of the tank 1 10, that is to say of the bottom 1 12.
- such an orientation of a rod 131 corresponds to a triangular shape of its cross section which “points” towards the lower zone 150.
- a base of the triangular shape of the cross section of a rod 131 is substantially parallel to the bottom 112, being oriented in opposition to the latter.
- the dimensions of a cross section of a rod 131 are chosen according to the type of fibers 120 to be sorted.
- the maximum dimension of the cross section of a rod 131 is between 0.5 and 10 times, preferably between 1 and 3 times, the average length of the fibers 120 intended to be sorted. Such a dimension makes it possible to reduce the risk of blocking of the fibers 120 in the network of obstacles 130, and maximizes their reorientation.
- the dimensions of the cross section depend on the application envisaged for the sorting device 100.
- fibers 120 are of the order of centimeters or millimeters in the case of synthetic fibers in wastewater, and of the order of micrometers in the case of fibrous biological organisms.
- the maximum dimension of the cross section corresponds to its diameter, while for a triangular section, the maximum dimension of the cross section corresponds to the length of its base.
- the fibers 120 can be recovered directly in the recovery zone 150, following their deposit at differentiated lateral positions on the bottom 1 12, or indirectly downstream of the zone recovery 150.
- the sorting device 100 can also include recovery units 160 for fibers 120, as shown in Figure 1.
- recovery units 160 taking the form of containers are arranged near the bottom 112, inside or outside the tank 110.
- the recovery units 160 thus make it possible to easily collect and recover the sorted fibers 120.
- the sorting device 100 operates as described below.
- the tank 110 is filled with a liquid loaded with fibers 120, which is intended to be filtered and whose fibers 120 are intended to be sorted.
- the liquid can for example include water.
- the liquid may also include a solute such as salt, i.e. the liquid includes salt water, such as sea water.
- the liquid is generally a liquid polluted by fibers 120, which are in particular synthetic fibers.
- Synthetic fibers can come from human activities, such as washing synthetic clothing.
- the synthetic fibers contained in the liquid include polyester, polyolefin, acrylic and nylon fibers.
- the tank 110 is previously filled with an identical or different liquid, so as to at least immerse the network of obstacles 130.
- the sorting of fibers is preferably carried out when the liquid contained in the tank 110 is almost at rest.
- the Reynolds number, characterizing the behavior of the liquid in the tank 1 10, is less than 1, preferably between 0.1 and 10 -6 .
- the fibers 120 contained in the liquid move under the effect of their own weight towards the bottom 1 12 of the tank 110.
- the tank 1 10 is arranged substantially vertically, in accordance with what has been been described further upstream.
- Each fiber 120 has its own mechanical properties. These mechanical properties include in particular geometric characteristics of the fiber 120, such as its length, and intrinsic mechanical properties, such as its flexibility, expressed in particular by its Young's modulus.
- the lateral displacement of a fiber 120 is inversely proportional to the adimensional elasto-gravitational number Be of the fiber, defined
- Figure 3 is a graphic representation of the lateral displacement of a fiber 120 for an elasto-gravitational number equal to 200 (chronophotograph on the left and plot ⁇ ) as well as for an elasto-gravitational number equal to 1000 (chronophotograph on the right and plot ⁇ ).
- the ratio between the length of the fiber 120 and the maximum dimension of an obstacle of the obstacle network 130 (also designated by ) corresponds here to 2.
- the obstacles are of circular section.
- Figure 4 is a graphic representation of the lateral displacement of a fiber 120 for an elasto-gravitational number equal to 200, for a ratio between the length of the fiber 120 and the maximum dimension of an obstacle of the network of obstacle 130 of 1 (plot ⁇ ) as well as for a ratio between the length of the fiber 120 and the maximum dimension of an obstacle of the obstacle network 130 of 2 (plot ⁇ ).
- the obstacles are circular in section.
- the network of obstacles 130 makes it possible to induce a differentiated lateral movement of the fibers 120, with a view to their sorting, or discrimination, according to mechanical properties.
- Figure 5 is a graphic representation of the lateral movement of a fiber 120 for obstacles of circular cross section (left chronograph and plot ⁇ ) as well as for obstacles of rounded triangular cross section, oriented towards the bottom of the tank (chronophotograph on the right and trace ⁇ ).
- the ratio between the length of the fiber 120 and the maximum dimension of an obstacle of the obstacle network 130 corresponds here to 2.
- the obstacles are of circular section.
- the elasto-gravitational number is equal to 200.
- a circular cross-section shape induces the lateral displacement of a fiber 120 to be greater in comparison to a triangular shape with rounded vertices, for a constant elasto-gravitational number.
- a triangular shape with concave sides can make it possible to induce a greater lateral movement of a fiber 120.
- the choice of such a shape can thus be made with the aim of amplifying the lateral movement, but it nevertheless implies a risk of trapping the fiber in the network of obstacles, in particular in the case of long and flexible fibers which risk getting stuck on a vertex of the triangular shape.
- the residence time of the fiber 120 in the obstacle network 130 is then increased.
- the ratio between the length of the fiber 120 and the maximum dimension of an obstacle of the obstacle network 130 can be chosen in the vicinity of 1 . In fact, long fibers tend to get stuck on obstacles 131.
- the orientation of the obstacles can be chosen such that a majority of the vertices of the triangular shape of the obstacle section are closer to the lower zone 150 of the tank 1 10 than of the upper zone 140 of the tank 1 10, in other words that the triangular shape “points” towards the upper part.
- the orientation of the obstacles can be chosen such that a majority of the vertices of the triangular shape of the obstacle section are closer to the upper zone 140 of the tank 1 10 than of the lower zone 150 of the tank 1 10, in other words that the triangular shape “points” towards the lower part.
- the surface roughness of the obstacles of the obstacle network 130 can be reduced in order to minimize the risk of trapping by friction of the fibers 120.
- a wastewater treatment installation 200 is schematically illustrated, such as a wastewater treatment plant.
- the treatment installation 200 comprises a wastewater treatment circuit 210, which may for example include a pretreatment station aimed at separating large solid elements, sediments and fats.
- a pretreatment station aimed at separating large solid elements, sediments and fats.
- such a circuit 210 then includes biological treatment basins and clarifiers.
- the treatment installation 200 may include a sorting device 100, preferably downstream of the treatment circuit 210. Indeed, it is preferable to filter water that has already been largely purified, so that the sorting device 100 can take effect under optimal conditions.
- the treated effluents leaving the treatment installation 200 are thus decontaminated and contain little or no fibers, particularly synthetic ones.
- the order of magnitude of the fibers is that of the millimeter.
- the dimensions of the obstacles of the network of obstacles 130, and their spacing, are then chosen in this same order of magnitude.
- a biological analysis installation may include a sorting device 100 for the characterization of biological fibers, in particular pathogens or filaments originating from cytoskeletons.
- a certain number of pathogens can be likened to fibers from a mechanical point of view, so that discrimination of the latter according to their mechanical properties can be used for characterization or identification purposes.
- a biological analysis installation of this type essentially comprises a sorting device 100, as well as any other means necessary for the analyzes to be carried out, such as for example means to guarantee the sterility of the installation.
- the order of magnitude of the agents and cytoskeletons comparable to fibers 120 is that of the micrometer.
- the dimensions of the obstacles of the network of obstacles 130, and their spacing, are then chosen in this same order of magnitude.
- the invention also relates to the use of a sorting device 100 for sorting fibers 120 as described above.
- the use of the device 100 can be in a biological analysis installation or a wastewater treatment installation 200, or any other type of installation or system.
- the invention also relates to a process for sorting fibers (120), in particular synthetic fibers, contained in a liquid loaded with fibers, the sorting being a sorting according to the flexibility of the fibers in particular.
- the method comprises the step of providing a sorting device 100, for example as described previously.
- the device 100 comprises a container 110 extending in a substantially vertical direction and being adapted to contain the liquid, and a network of obstacles 130 arranged in the container 110, the network of obstacles 130 being configured so as to be able to be crossed by a fiber 120 from an upper zone 140 of the container towards a lower zone 150 of the container, called recovery zone, under the effect of gravity.
- the method then comprises the step of introducing liquid loaded with fibers into the sorting device 100, that is to say into the container 1 10.
- the fiber-laden liquid may be a liquid polluted by synthetic fibers
- the container 110 may have been filled with liquid, for example not loaded with fibers, in whole or in part, and for example at least so as to cover the network of obstacles 130.
- the method then comprises the step of letting the sorting device 100 and the fiber-laden liquid contained rest, in order to operate under the effect of gravity a sorting of fibers 120 in particular according to their flexibility, by depositing at differentiated lateral positions in the recovery zone.
- the step of letting the device and the liquid rest can last from a few minutes to a few hours or days, depending on the type of liquid and fibers in particular.
- the step of letting the device and the liquid rest is preferably a step during which no active intervention, external or internal, is carried out. Only the effect of gravity is sufficient to sort the fibers, which move towards the bottom of the container 1 10 under the effect of their weight while moving laterally, which has the effect of sorting the fibers 120.
- the method then includes the step of recovering the sorted fibers 120 at the recovery zone.
- the fibers 120 for example synthetic fibers, can for example be recycled, or simply removed from the liquid which is thus decontaminated.
- the recovery of a certain type of fiber at a certain lateral position at the recovery zone can also be used to indicate the type of pollution to which the liquid is exposed.
- the fibers can be biological fibers, and can be characterized according to the sorting carried out.
