Definitions

  • This disclosure relates to a rainwater treatment device configured to removably receive a cartridge with a substrate for treating a fluid such as rainwater. It further relates to the use of such a device for treating rainwater and to a method of producing such a device.
  • rainwater treatment devices which are designed to be mounted and used underground.
  • a rainwater treatment device receives a filter cartridge including a filter substrate in a cartridge accommodation space.
  • the substrate is configured to treat rainwater, e.g., for filtering substances such as metallic particles out of the rainwater.
  • This device is particularly useful near roads, where metal contaminations occur, e.g., due to vehicle breaking and/or drainage of building roofs containing metal.
  • the filtered water is fed back into the environment, for example, into the groundwater, or into a river or a lake.
  • the cartridge may be provided with a plurality of sidewall openings through which rainwater can enter.
  • the cartridge accommodation space of the device is designed such that, upon receiving a cartridge, a space remains between the cartridge side wall and the accommodation space side wall. Rainwater thus enters said space and flows into the cartridge through the sidewall openings. This enables a large rainwater throughput.
  • the space between a cartridge and the accommodation space side wall constantly fills up with new rainwater. Consequently, rainwater enters the cartridge through all of the cartridge sidewall openings.
  • Embodiments of a rainwater treatment device in accordance with the present disclosure are defined by the claims below.
  • One aspect of this disclosure relates to rainwater treatment device comprising a fluid inlet, a fluid outlet, a cartridge accommodation space for removably receiving a cartridge including a substrate for treating rainwater, a fluid receiving space for receiving fluid flowing out of the accommodation space, the fluid receiving space being fluidly connected to the fluid outlet by a drainage fluid path, and an overflow damming element provided in the drainage flow path and/or the fluid receiving space for damming up fluid in the fluid receiving space and the accommodation space and for reducing fluid throughput in the drainage flow path towards the fluid outlet for as long as the overflow damming element does not overflow.
  • the overflow damming element is provided in the drainage flow path.
  • the device may comprise one or several overflow damming elements.
  • a fluid e.g., rainwater
  • a fluid entering the device through the fluid inlet is (possibly, after having passed one or several other treatment stages) led into a cartridge received in the accommodation space.
  • the rainwater is treated (e.g., filtered in the cartridge) and then flows out of the cartridge (out of the accommodation space). The rainwater then flows into the fluid receiving space.
  • At least the part of the fluid receiving space may be provided below the cartridge accommodation space.
  • the term "below” makes reference to the direction of gravity when the rainwater treatment device is positioned/oriented so as to be in use. Fluid flows from the fluid receiving space through the drainage flow path to the fluid outlet.
  • the overflow damming element dams up fluid in (at least a part of) the fluid receiving space and/or in the accommodation space.
  • fluid first dams up in the fluid receiving space and then additionally also in the accommodation space.
  • fluid is, hence, dammed up in the cartridge.
  • the cartridge is therefore wet more homogenously.
  • different parts of the substrate(s) are wet for similar periods of time. This is true both when the fluid throughput is high (e.g., during periods of heavy rainfall) and when the fluid throughput is low (e.g., during periods of low rainfall).
  • As rainwater is dammed up in the accommodation space water may fill a space between a received cartridge and the accommodation space, also when the water throughput is low. Consequently, rainwater enters through a large number of or all of a plurality of openings in the sidewall of the cartridge, also when the rainwater throughput is low.
  • the overflow damming element is configured to reduce the fluid throughput in the drainage flow path towards the fluid outlet for as long as the overflow damming element does not overflow. When it overflows, the throughput is no longer (or at least to a lesser degree) reduced so that the damming up of fluid is not excessive.
  • the reduction of the fluid throughput in the drainage flow path is defined as a reduction relative to the fluid throughput in the drainage flow path towards the fluid outlet when the damming element overflows.
  • the reduction of fluid throughput for as long as the damming element does not overflow may be a reduction to zero.
  • the reduction is not absolute also when there is no overflow.
  • the damming element allows some fluid throughput also before overflowing.
  • the device according to the present invention promotes a more homogeneous use of cartridges (and of the substrates therein, in particular) irrespective of the level of fluid throughput. Costs are therefore saved as cartridges need to exchanged less frequently. The life span of cartridges is maximized as the device may ensure that the accommodation space and received cartridges run dry irrespective of the level of fluid throughput.
  • the overflow damming element comprises a wall of another type of baffle. That said, that damming element may also consist of one or more walls and/or one or several other types of baffles.
  • the damming element when the damming element is a wall, it may reduce fluid throughput in the drainage flow path towards the fluid outlet for as long as the water level does not exceed the height of the wall (i.e., before the wall overflows). When the wall overflows with fluid, the fluid throughput is no longer "reduced".
  • the implementation of the damming element with a wall is especially advantageous due to the simplicity of the construction.
  • the provision of a wall in the drainage flow path may be effected cost-efficiently.
  • the wall may be welded to the drainage flow path. This is simpler than, e.g., a complex construction of drainage system using different pipes etc.
  • the damming element in the form of a wall also requires less space.
  • the overflow damming wall is particularly useful for a rainwater treatment device of compact build.
  • the overflow damming element consists of a curved or straight wall portion.
  • the shape may conform to the shape of an adjacent wall part of the cartridge accommodation space and/or another constituent of the rainwater treatment device. This is especially advantageous when the accommodation space has an at least partially cylindrical shape. The latter is, e.g., the case when cylindrical cartridges are used.
  • the wall portion preferably has a height which lies in a range of 50% to 100% of the height of the type of cartridge which the accommodation space is configured to receive.
  • the height of the wall portion lies in a range of 50 to 100% of the height of a side wall of the cartridge accommodation space. The mentioned heights may aid in ensuring an adequate amount of reduction of fluid throughput in the drainage flow path.
  • the overflow damming element comprises at least one opening and/or leak allowing fluid to pass the overflowing damming element in the direction of the fluid outlet also when the fluid damming element does not overflow. This way, it is ensured that the fluid throughput is not zero also when the damming element does not overflow. Thus, it is a cartridge is not hindered from running dry.
  • the opening and/or leak may be formed in a lower portion of the damming element, preferably at the bottom thereof ("bottom” referring to the direction of gravity when the device is oriented in the position for use).
  • the opening and/or leak is arranged at or adjacent to the bottom of the fluid receiving space. The amount of fluid remaining in the fluid receiving space and/or the accommodation space when there is there is no more fluid throughput is reduced to zero or at least minimized. Moisture problems are, hence, avoided or minimized.
  • the overflow damming element is welded to the fluid receiving space and/or the drainage flow path, and the weld is leaky.
  • the damming element may be a curved or straight wall (or partially curved and partially straight).
  • the wall may be welded to the bottom of the fluid receiving space and/or the drainage flow path.
  • Making the weld "incomplete" such that the weld is leaky is an especially efficient way of ensuring that some fluid may always pass the damming element.
  • the leaky weld thus promotes that the accommodation space and, hence, a received cartridge runs dry when no new fluid enters the device.
  • the combination of the leaky weld with a wall as a fluid damming element is particularly advantageous.
  • the rainwater treatment device comprises a substrate cartridge including a substrate for treating rainwater.
  • the cartridge is removably mountable in the accommodation space.
  • the cartridge preferably comprises openings for letting fluid enter the cartridge in a side wall.
  • the cartridge does not comprise any openings for letting fluid enter in a top wall. Therefore, fluid preferably enters the cartridge from the plurality of openings in the side wall.
  • the cartridge is received in the accommodation space and a fluid inflow space is formed between a side wall of the accommodation space and the cartridge for letting a fluid flow from the fluid inflow space into the cartridge laterally.
  • the rainwater treatment device preferably comprises a sediment settling space which is separate from the cartridge accommodation space and the fluid receiving space.
  • the sedimentation treatment preferably does not (or at least primarily does not) occur in the accommodation space and/or the fluid receiving space and/or the drainage flow path.
  • the rainwater treatment device may have a modular construction comprising separable modules. This increases the versatility of the device and allows changing the relative orientation of components. This simplifies connection with other elements, etc.
  • the device comprises an inflow module.
  • the inflow module is provided with the inlet of the device and is axially rotatable with respect to at least one other module.
  • the inlet is preferably oriented in a lateral direction with respect to a central axis of at least one (preferably at least partially cylindrically shaped) further module.
  • the inflow module may be axially rotated so as to orient the inlet so as to conform to the surrounding (e.g., the orientation of a part to be connected to the inlet) in which the assembly is used/installed.
  • the device comprises a treatment module including the accommodation space, the fluid receiving space, and at least a part of the drainage flow path (preferably the entire drainage flow path).
  • the treatment module also comprises the fluid outlet of the device.
  • the rainwater treatment device comprises a settling module including a sediment settling space (preferably, a settling space as described above).
  • the sediment settling space may be provided at the floor of a shaft/manhole part of the device.
  • the substrate cartridge is at least partially cylindrically shaped and comprises a centrally located hollow space connected to the bottom of the substrate cartridge.
  • the space being "hollow” in this context means that no substrate is provided in said space. Fluid can be drained out of the cartridge through the hollow space.
  • the bottom of the substrate cartridge comprises perforations. These perforations are preferably located around the central hollow space.
  • the at least one substrate comprises a filter material, preferably selected from the group consisting of iron oxide hydrate, active carbon and/or zeolite, or any combination thereof.
  • a filter material preferably selected from the group consisting of iron oxide hydrate, active carbon and/or zeolite, or any combination thereof.
  • the cartridge prefferably be separately exchangeable/replaceable. In other words, it is preferable if an old cartridge is removable from the device and replaceable with a new one. A worn cartridge may, hence, be removed from the accommodation space and replaced with a new one.
  • the device comprises a cartridge
  • the cartridge comprises at least one opening in a side surface through which fluid can enter from the accommodation space when the cartridge is received in the accommodation space.
  • the disclosure also relates to the use of a rainwater treatment device according to any one of the described embodiments for treating rainwater.
  • the use may take place above ground and/or underground.
  • the disclosure also relates to a method of producing a rainwater treatment assembly according to any of the embodiments described above and to a cartridge for a rainwater treatment assembly according to any one of the embodiments described above.
  • the method comprises the step of welding the overflow damming element to another part of the assembly, wherein the weld is made such that it comprises at least one leaky spot.
  • the cartridge may contain a single substrate but preferably it comprises two or more substrates.
  • the substrate (s) is/are configured to filter filterable substances in the fluid such as mineral hydrocarbons, and/or dissolved metallic particles, especially dissolved heavy metals.
  • an exit is located in a lower part of the cartridge. More preferably, the exit is located at a lower end of the cartridge. The exit may be provided in a bottom surface of the cartridge.
  • upper and lower used when referring to the upper and lower parts/ends of the cartridge and the term “top” (e.g., in “top entrance”) pertain to the cartridge's orientation when the rainwater treatment device is brought into its operating position. Put differently, the terms pertain to the orientation when gravity pulls (substantially) in the direction from the upper part / top towards the lower part / bottom of the device.
  • the device is, hence, configured so as to be oriented such that a fluid flows into the cartridge at an upper position and flows out of the cartridge at a lower position under the influence of gravity.
