Definitions
- Filter device comprising a bionic filter element and method for separating microplastics from fluids
- the invention relates to a bionic device and a method for separating microplastics from a fluid
- the device consists of at least one housing and at least one filter element or at least one self-supporting filter element, which is gill-shaped and the fluid enters the housing and the filter element or the self-supporting filter element at one end via an inlet opening and at the other end the separated microplastics accumulate as retentate through a circular flow within the filter element and can be drained or sucked off centrally in the area of the filter element via a retentate drain and can be collected and removed in a container, wherein the housing and the filter element or the self-supporting filter element have an opening angle to the inlet opening of a « 90 ° to generate the circular flow and are at least partially conical, wherein the filter element at least partially has a mesh or pore-shaped filter structure and the fluid exits laterally through the mesh or pore-shaped filter structure of the filter element.
- EP 4041429 A1 describes a separator for separating microplastics from wastewater comprising a chamber with an inlet and an outlet, a sieve structure forming a permeable barrier between the inlet and the outlet, and a washing device for washing the sieve structure, wherein the sieve structure comprises a first net within the chamber.
- EP 4037804 A1 discloses a device for filtering water, comprising a filter which forms a permeable container for the liquid to be filtered, an actuation inlet for providing a water flow, a filter liquid inlet for providing the liquid to be filtered to the filter and a rotatable cleaning structure for cleaning the filter, wherein the structure comprises at least one scraper.
- the scraper is rotatably mounted with respect to the first surface of the filter and has at least one rotatable element which is arranged to receive the water flow.
- EP 1528139 A2 describes a device for cleaning tissues comprising a container for the relative movement of the tissue to be cleaned, a means for introducing a working fluid to the container, a cross-membrane filter, a compressor-driven refrigeration system and a heat exchanger with a coolant side and a pump to move the working fluid from the container through the working fluid side of the heat exchanger and then through the filter means.
- US 2022154385 A1 discloses a washing machine with a hydrocyclone and a filtration hybrid system, in which the fibers that break off during the washing process are passed through the hydrocyclone to be separated from the drain water.
- the fibers separated from the drain water are transferred to the microfilter structure located behind a detergent box together with the water remaining in a tub at the end of the pumping process, while the fibers are retained by the filter structure in order to release and drain the cleaned water into the tub.
- WO 2023/172344 A1 describes a method for improved, more efficient or more effective filtering of materials, such as microplastics, from liquids.
- a vortex filter provides vortex cross-flow filtration, whereby the vortex filter has a tapered spiral configuration that can be conical and can also assume a conical-helical configuration.
- At the bottom of the vortex filter there is a collecting container through which flow is continuously carried out, whereby the microplastics are collected and can be removed.
- a surface filter which is intended to be a further development of a so-called Sanderson filter.
- Two flow paths are provided in the housing of the filter, whereby a first flow path guides a fluid with a smaller proportion of microfibers laterally through the filter structure, while a second flow path runs essentially along a central longitudinal axis, via which residues from the first flow path can be entrained towards the outlet and prevent the filter from becoming clogged.
- WO 2013/184814 A1 shows a Sanderson filter.
- DE 19748233 A1 discloses a filter device for solids, particularly coarse dirt, from wastewater, in which the wastewater is initially accelerated helically via an inlet and a subsequent spiral channel. A vortex is generated along a filter element below the inlet, which presses the solids contained in the wastewater against the wall of the filter element, whereby solids-free wastewater can exit the filter element through openings laterally present in the filter element. The remaining solids can be moved along the filter element in the direction of flow to the outlet and continuously deposit in a solids container or a sedimentation basin.
- the filter element has a mesh or pore-shaped filter structure, which ensures that the fluid can escape from the mesh or pore-shaped filter element and the solids within the filter element If the filter element is arranged as an insert in the housing, it can be removed and/or washed individually.
- the retentate can be collected in a container and removed from the container, whereby the container can be made of stainless steel or plastic. It is also possible to pass the retentate directly on by taking it to further technical processing, for example a centrifuge, in order to separate fluid adhering to the retentate or to feed it to further filtration, for example. Furthermore and additionally, the retentate can flow into a press that can compress the retentate and remove remaining fluid from the retentate.
- the shape of the container is variable and depends on the respective design of the bionic device, in particular the filter element and/or the housing surrounding the filter element.
- the bionic device can have an analog or digital control mechanism, according to which the amount, strength, i.e. the speed or pressure and temperature of the fluid inlet into the bionic device is regulated.
- the helical flow within the filter element can also be generated or at least supported by the amount, speed and/or pressure and/or temperature of the fluid inlet.
- the interruption of the fluid inlet and/or the drainage or suction of the microplastics or solids from the area of the filter element in general, for example the microplastics still suspended in the fluid or the microplastics already at the bottom of the filter element, can also be ensured by the control mechanism.
- the control mechanism allows the solids to be drained away from the area of the filter element in order to enable ongoing, continuous or periodic cleaning of the fluid by the bionic filter element. This also includes the generation of a backflow into the fluid in the area of the base of the filter element so that any solids adhering to the walls of the filter element can be fed back into a removal, drainage or suction process. The induced backflow can therefore be used to clean the filter element.
- the control mechanism can be designed as a valve or as a flap or sieve or hydrodynamic resistance and can control the opening or closing of a valve unit or flap arrangement or a sieve or a hydrodynamic resistance.
- the control mechanism can control or include one or more valves, flaps, sieves or hydrodynamic resistances.
- one control mechanism can be arranged in the area of the retentate drain and another in the area of the filtrate drain.
- the control mechanism regulates, for example, the switching of valves and is intended to generate a suction/negative pressure with turbulent flow in the area of the filter element. This becomes stronger if, for example, a valve in the area of the filtrate drain closes while a valve in the area of the retentate drain opens.
- the retentate valve is opened, for example, the particles still suspended in the fluid within the filter element in general and/or in the fluid within the filter element and/or the microplastics or microparticles already in the area of the bottom of the filter element are sucked out or drained away and can be collected in a container and then removed.
- the control mechanism determines the cleaning interval, i.e. how often or at what intervals the retentate valve is opened, and the cleaning duration, i.e. how long the retentate valve is open, for example.
- the control mechanism then backwashes the filter element in the form of a pressure pulse to the outer wall of the filter element in order to remove microplastics or particles adhering to the filter element wall with the retentate fluid.
- cleaning or backwashing can also be carried out by using the control mechanism in the area of the filtrate outlet to force fresh water against the filter element via a hose that is attached to the filtrate outlet, for example, before cleaning the filter element.
- Backwashing with fresh water can be pulsed or continuous. Cleaning with fresh water is preferably carried out with the filtrate valve and retentate valve closed, for example.
- the microplastics or particles detach from the filter structure.
- the control mechanism in the area of the retentate drain is opened, the microplastics or particles detached in this way are sucked off or slid away with the microplastics or particles already present in the filter element before cleaning or backwashing and can be collected in a container and then removed.
- the filter element can also be cleaned by backwashing by alternating filtrate fluid and/or fresh water in order to make the cleaning as effective and cost-effective as possible.
- the control mechanism usually regulates a cleaning interval in a range of 13s to 86s and a cleaning duration in a range of 0.6s to 6.5s.
- the interval and duration can be set variably and include longer or shorter cleaning intervals or durations.
- microplastics adhering to the inner wall of the filter element in the area of the filter element or the filter structure can initially be detached from the filter structure by the pressure pulse triggered on the outer wall of the filter element, for example by briefly closing and then reopening the filtrate valve, and can be drained or sucked away with the microplastic particles already present within the filter element when the retentate valve is opened.
- the detached microplastic particles can therefore be sucked away or drained away with the particles already suspended within the filter element in general or in the fluid within the filter element and/or with the particles already located in the area of the bottom of the filter element and collected in a container and then removed.
- a pressure pulse to detach adhering microplastics or particles is optional, i.e. it can be carried out, but is not absolutely necessary.
- the filter element can also be cleaned when the filtrate valve is open, for example, by the control mechanism opening the retentate valve and draining or sucking off the retentate without the filtrate valve having to be closed.
- additional sensor monitoring can be carried out, e.g. via the pressure difference on the filter element, which is connected to the control mechanism. If the sensor measures that a lot of microplastics or particles are accumulating in the filter and the filter element is in danger of becoming clogged, the control mechanism can control the valves or flaps or sieves or hydrodynamic resistors and carry out cleaning.
- the cleaning interval can therefore be flexible depending on the load on the filter.
- the design of the bionic device is chosen so that flange connections are present in the area of the inlet opening. These can also be present in the area of the housing or the filter element or the pre-chamber and are intended to provide a tight connection between the area of the inlet opening in the filter element and the housing or the pre-chamber.
- the pre-chamber can, for example, be designed in two parts with the housing and/or the filter element, or the pre-chamber can be designed in one piece with the housing or only the housing with the filter element.
- the two- or multi-part design and one-piece design of the housing, the pre-chamber and the filter element with or without an insert or adapter are in the foreground, whereby all possible variations are claimed as part of the invention, but not all of them are listed here exhaustively.
- bionic devices or filter elements can be arranged or connected in series. These can all have the same or different design with regard to the arrangement of the filter element, the shape of the insert or adapter, the housing or the pre-chamber.
- filter elements can also be arranged in one housing.
- the other elements mentioned in the previous designs such as a housing with or without an insert or adapter or a pre-chamber with or without an insert or Adapters may be present in one or more housings or devices arranged together or separately to improve the purification of the fluid containing the solids.
- the bionic device can also include a vent and/or a siphon to ensure that the fluid drains away and to prevent odors from contamination the environment.
- the present invention also discloses a method for separating solids, in particular microplastics, from fluids, wherein the fluid enters a filter element via an inlet opening, generates a circular flow within a filter element through an at least partially conical design, wherein the filter element at least partially has a mesh or pore-shaped filter structure and then the fluid exits laterally through the mesh or pore-shaped filter structure of the filter element and the solids can be drained or sucked off as retentate in the region of the bottom of the filter element or a container arranged there, which can be a separate part or a component of the filter element, and can be collected and removed.
- the choice of opening angle depends on various parameters such as the type of fluid, the type of solids, the flow velocity, the pressure and/or temperature of the fluid.
- the aforementioned parameters can, individually or in combination, determine the size of the opening angle relative to the inlet opening in order to enable optimal separation of the solids from the fluid. This applies in particular to the selection of the insert or adapter as part of the pre-chamber to create the circular flow.
- the insert or adapter as part of the pre-chamber or as an external part without a pre-chamber can, individually or in combination with the aforementioned parameters, help to determine the size of the opening angle relative to the inlet opening and to generate optimal circular flow and/or achieve filtration of the fluid.
- the choice of insert or adapter inside or outside the pre-chamber therefore also contributes to the generation of the circular flow in the filter element.
- the selection of the insert or adapter or the parameters is also important for the arrangement of the other components of the bionic device such as the housing, the pre-chamber and the filter element as a separate element or part of the housing or the filter element of the bionic device.
- the filter element requires a smaller opening angle at the inlet of the filter element (40°) in order to ensure that the solids sink or roll down the wall areas of the filter element more easily and thus ensure better separation of the solids from the fluid.
- the analogous considerations also apply when changing the size of the solids, the type of fluid, the pressure and/or the flow speed as parameter variations.
- the circular flow of the fluid with the solids can be determined by choosing the aforementioned parameters and/or choosing the insert or adapter to generate a circular flow. It is not important whether the insert or adapter is part of the housing of the filter element, the pre-chamber or the housing or is arranged separately from it, but that an optimized separation of solids and fluid can be achieved by generating a circular flow within the filter element.
- the fluid and/or the retentate can be drained or removed from the bionic device periodically or continuously. This is done by means of an analog or digital control mechanism that drains or sucks the retentate out of the area of the filter element.
- This bionic device is intended to be used in water remediation, wastewater and food processing, in particular for removing microplastics from the wastewater of dishwashers or washing machines.
- other applications can also be used, so the above possible uses are only examples and are not exhaustive.
- a siphon was formed with the filtrate outlet pipe and valves were installed as control mechanisms in the retentate and filtrate outlets.
- the volume flow was provided with the spiral-shaped pre-chamber.
- the control mechanism comprised two automatic valves in the area of the filtrate and retentate outlet to clean the filter element at certain intervals.
- the filtrate outlet was opened and the retentate outlet for 0.6 s and 1.3 s when 10 I and 20 I passed through the filter element.
- the cleaning effect on the volume flow was tested with plastic flock fibers (0.1 g/l), as this combination is most similar to the application in washing machines. 10 I were filtered and the filter element was cleaned after 5 I and 10 I. This process was repeated five times. Between the individual tests, the test bench was rinsed with clean water and the filter element was washed manually to remove any remaining particles.
- control mechanism closed the valves, filled the filter element with clean water and vented it, and mixed 20 l of tap water, 0.5 g of flock fibers and 5 ml of liquid detergent together.
- the control mechanism opened the valve in the area of the filtrate outlet to start the test. Cleaning was automatically stopped when 5 l and 10 l passed through the filter element. After the second cleaning, the test was stopped and the control mechanism closed the valves.
- Periodic cleaning can prevent the filter element from becoming clogged. Cleaning increases the volume flow of a fiber suspension compared to a non-cleaned filter fabric. The effect can be even stronger if the cleaning frequency is increased.
- FIG. 1 shows the bionic device 1 in a schematic side view. It is schematically indicated that a fluid (upper arrow) enters a pre-chamber 11. Below the pre-chamber 11 there is a housing 2 into which the fluid flows from the pre-chamber 11 and on which a vent 12 is arranged. Inside the housing 2 there is a filter element 3 (not shown) through which the fluid flows. The fluid flow or the concentration of the solids in container 7 is regulated by a control mechanism 8. In the area of the vertical fluid outlet there is a siphon 10 which serves, among other things, to regulate the fill level in the housing 2.
- FIG. 2 shows a filter element 3 with an inlet opening 4, a filter structure 5 and the opening angle 6.
- the filter structure 5 tapers conically from the inlet opening 4 to the outlet opening in the central lower area of the filter element 3.
- the conical shape of the filter element 3 enables the particles or solids to sink or roll along the filter element 3, which are caught, collected or concentrated in a central area of the filter element in the form of a collecting container, a capsule or sleeve.
- the filter element 3 itself has a rigidity that largely withstands tensile, shear, bending and/or torsional forces. This is important so that the filter element 3 can ensure a constant conical or at least concave shape that withstands the helical, circular or circular movement of the fluid with the solids within the filter element 3.
- the filter element 3 is provided with frame elements which run through the filter element 3 in the form of ribs or gills.
- the filter element 3 has a mesh or pore-shaped filter structure 5 (not shown) between the rib or gill-shaped frame elements, through which the fluid can escape from the mesh or pore-shaped filter element 3, while the solids remain within the filter element 3.
- Figure 2 shows the filter element 3 with housing 2 with a pre-chamber 11 and an insert/adapter 15 in a two-part embodiment in a vertical cross-section. A fluid with solids flows (indicated by the upper vertical arrow) into a pre-chamber 11, in which an insert/adapter 15 is arranged.
- the insert/adapter 15 is in the present case spindle-shaped, so that the fluid flowing in with the solids already experiences a circular rotation within the pre-chamber 11.
- the pre-chamber 11 is connected to the housing 2 via flange connections 9.
- the fluid with the solids flows from the pre-chamber 11 into the filter element 3 via an inlet opening 4. Due to the induced circular flow, the solids of the fluid in the area of the filter element 3 are pressed laterally against the filter structure 5, which in this case is surrounded by gills or arches with frame elements, and move in a rolling or sinking movement towards the bottom of the central area of the filter element 3.
- the solids can also be sucked out of the collecting container, the capsule or the sleeve via a valve or removed as retentate or concentrate via an outlet 14 of the bionic device 1.
- the fluid that has escaped laterally from the filter structure 5 and been filtered can be fed back into the fluid or (waste) water circuit via a filtrate outlet 13.
- Figure 3 shows the filter element 3 with housing 2 with a pre-chamber 11 and an insert/adapter 15 in a two-part embodiment in a vertical cross-section.
- a fluid with solids flows (indicated by the upper vertical arrow) into a pre-chamber 11 in which an insert/adapter 15 is arranged.
- the insert/adapter 15 is in the present case spindle-shaped, so that the fluid flowing in with the solids already experiences a circular rotation within the pre-chamber 11.
- the pre-chamber 11 is connected to the housing 2 via flange connections 9.
- the fluid with the solids flows from the pre-chamber 11 into the filter element 3 via an inlet opening 4.
- the solids of the fluid in the area of the filter element 3 are pressed laterally against the filter structure 5, which in this case is surrounded by frame elements in the form of gills or arcs, and move in a rolling or sinking movement towards the bottom of the central area of the filter element 3.
- the filter structure 5 which in this case is surrounded by frame elements in the form of gills or arcs, and move in a rolling or sinking movement towards the bottom of the central area of the filter element 3.
- a collecting container, a capsule or a sleeve in which solids are collected or concentrated.
- the solids that have reached the collecting container, the capsule or the sleeve can be removed as retentate or concentrate via an outlet 14 of the bionic device 1.
- the fluid that has escaped laterally from the filter structure 5 and been filtered can be fed back into the fluid or (waste) water circuit via a filtrate outlet 13.
- Figure 4 shows a vertical cross-section of the pre-chamber 11 with a spindle-shaped insert/adapter 15.
- a spindle-shaped insert/adapter 15 arranged within the pre-chamber 11, which widens conically towards the outside, which sets a fluid with solids in a circular preferential movement in the direction of flow.
- the fluid which is set into a preferential movement by the spindle-shaped insert/adapter 15, can flow with the solids into a subsequent filter element 3 (not shown).
- the solids Due to the circularly induced flow in the area of the filter element 3, the solids are separated from the fluid at the filter structure 5 (not shown), in that the fluid exits laterally through the mesh-like or pore-like filter structure 5 and the solids sink downwards or roll downwards along the filter structure 5.
- Figure 5 shows a plan view of a helical prechamber 11 which has a circular flange with holes.
- a fluid with solids is set in a circular preferential movement in the direction of flow by the helical design of the prechamber 11.
- the fluid with the solids exits as flatly as possible and directly onto the filter structure 5 (not shown) at the edge of the filter element 3 (not shown) through an opening in the helical prechamber 11.
- the fluid with the solids can then flow into the filter element 3 (not shown) following in the direction of flow.
- the solids Due to the circularly induced flow in the area of the filter element 3 (not shown), the solids are separated from the fluid at the filter structure 5 (not shown) by the fluid exiting laterally through the mesh-like or pore-like filter structure 5 (not shown) and the solids sinking or rolling downwards along the filter structure 5 (not shown).
