in an inlet of a storm drain. Commonly the filter unit is fixedly mounted or
attached to the inlet of the storm drain in question. This approach results in a
troublesome and time consuming installation process. Also the removal of the
filter may be troublesome and time consuming. Moreover, the installation of a
filter may reduce the capacity of the storm drain concerned.
EP 2 620 561 A1 discloses a floating filter device for filtering storm
water inside a storm drain. The disclosed filter device uses various materials
for removing pollutants or contaminants from the storm water being filtered.
The disclosed device may suffer from stability problems when e.g. being
subjected to large flows of storm water.
Hence, there is a need for an improved device for filtering storm water
inside a storm drain.
Summary of the invention
lt is an object of the present invention to provide an improvement of the
above techniques and prior art.
A particular object is to provide device for filtering storm water inside a
storm drain. This and other objects as well as advantages that will be
apparent from the following description of the present invention are achieved
by a device for filtering storm water inside a storm drain according to the
independent claim. Preferred embodiments are defined in the dependent
claims.
Hence a device for filtering storm water inside a storm drain is

By means of the present invention it is possible to provide an improved
device for filtering storm water inside a storm drain by providing a metal
capturing ballast unit in the device. The use of a metal capturing ballast unit
brings about that the device experiences an increased stability as the ballast
unit counteracts any tilting momentum exerted to the device from e.g. large
flows of storm water reaching the device during heavy rainfall or from objects
impinging on or building up on the device. Moreover, the use of a metal
capturing ballast brings about that the storm water present in the storm drain
will contact the metal capturing ballast when the device is floating in the storm
drain. This brings about that metals present in the storm water of the storm
drain may come into contact with the metal capturing ballast and hence be
captured, resulting in that the metal is removed from the storm water of the
storm drain.
Hence, the present invention is based on the realisation that the use of
a metal capturing ballast unit may improve the stability of the device and at
the same time remove metal form the storm water in which the device is
floating during use.
The solid material of the metal capturing ballast unit may comprise slag
from production of raw iron by means of a blast furnace. The use of slag from
production of raw iron brings about that an efficient metal capturing is
provided and at the same time ballasting of the device is provided. Moreover,
the use of slag implies that the availability of the material is good and the
price is favourable.
The solid material of the metal capturing ballast unit may be produced
by cooling the slag by means of fresh water, which is advantageous in that a
porous material having an increased contact surface may be provided,
resulting in that the efficiency of capturing metal is improved.
The solid material of the metal capturing ballast unit may be a solid
granular material, which is advantageous in that the handling of the material
is simplified as the material may easily be loaded in the device.
The filter unit of the device may comprise a material selected from the
group consisting of porous polypropylene, slag from production of raw iron,
10

and activated carbon, which is advantageous in that an efficient filter unit may
be provided.
The metal capturing ballast unit of the device may further comprise
activated carbon, which is advantageous in that further pollutants or
contaminants may be removed from the storm water of the storm drain.
The metal being captured may be selected from the group consisting of
atomic metal, ionic metal, or compounds comprising metal, which is
advantageous in that metal may be captured in various forms.
The metal being captured may be a heavy metal, which is
advantageous in that toxic metals may be captured.
The device may further comprise a sheet of porous polypropylene
extending radially outside the device and being at least partially arranged at
the surface of the storm water, which is advantageous in that pollutants and
contaminants, such as oil, present on at the surface of the storm water in the
storm drain may be removed or captured.
The device may further comprise a compartment arranged below the
surface of the storm water, wherein the compartment may be provided with
porous polypropylene, which is advantageous in that further pollutants or
contaminants may be captured or removed from the storm water of the storm
drahm
As indicated above, the solid material of the metal capturing ballast unit
may comprise slag from production of raw iron by means of a blast furnace.
Slag of the present type is available under the trade name of ”“Hyttsand”” from
SSAB Merox AB, Oxelösund, Sweden. ln the following description, the
wording hyttsand will be used when exemplifying slag of the present type
used in embodiments of the present invention.
Further features of, and advantages with, the present invention will
become apparent when studying the appended claims and the following
description. The skilled person will realize that different features of the
present invention may be combined to create embodiments other than those
described in the following, without departing from the scope of the present
inven?on.

Brief description of drawinqs
Aspects of the invention will be described in more detail below, with
reference to drawings illustrating embodiments of the invention
Figure 1 iiiustrates a device for fiitering stormwater according to an
embodiment of the present invention.
Figure 2 iiiustrates a device for fiitering stormwater according to an
embodiment of the present invention.
Detailed description
The following detailed descriptions of embodiments of the invention are
included as examples to improve the understanding of the invention and
should not in any way be interpreted as limiting the scope of the invention.
Figure 1 iiiustrates a device 1 for fiitering storm water. The device 1
may typically be used inside a storm drain, such as for example a storm drain
of a road or street or in the vicinity of a road or a street, for fiitering of
stormwater and capturing of compounds and particles present in the
stormwater. The device 1 is arranged to form a gap between the device 1 and
an interior wall of the stormdrain. The gap is arranged so that objects, such as
sediment, sand, gravel, pebbles, twigs, trash and similar can pass by the
device 1 to a catchbasin of the storm drain. Hence, the device 1 is arranged
to cover less than 100% of the cross section area of the stormdrain, such as,
for example, 50-90%.
Parts for the filter unit 2, the floating carrier 4 and the metal capturing
ballast unit 6 may be made of, for example, injection moulded plastic material.
For the purpose of fiitering storm water, the device 1 has a filter unit 2
for fiitering of storm water and removal of contaminants, carried by a floating
carrier 4. The floating carrier according to this example is an air filled plastic
container, but it is realised that other suitable materials and devices may be
used, such as, for example a body of foamed plastic. A ballast unit 6 provides
ballast to the device 1 and further comprises a solid material for capturing
metal from the storm water. When used in a storm drain (the storm drain is
10
15
20
25
30

not illustrated), the device 1 is arranged such that it floats in the storm water
with a surface of the storm water typically in the area of dotted line 5. The
ballast unit 6 may prevent the device from turning over, such as if hit by
gravel or rocks falling into the storm drain, or hit by heavy flows of storm
water.
Storm water entering the storm drain will, at least in part, contact the
filter unit 2, whereby storm water will pass through the filter unit 2. ln this
embodiment, the filter unit 2 comprises a cover 20 arranged to efficiently
allow storm water to enter the filter unit 2 while larger particles and objects,
such as gravel, rocks, or branches may bounce off the cover 20 and fall into
to the bulk of the storm water in the storm drain. For the purpose of cleaning
the storm water by removal of pollutions or contaminants, filter unit 2 may
comprise a material selected from porous polypropylene, slag from production
of raw iron, and activated carbon, or combinations thereof. Thus,
contaminants in the storm water may be captured, adsorbed or absorbed to
the material and, thus, removed from the storm water. As one result, storm
water with decreased levels of contaminants may leave the filter unit 2 and
enter the storm drain. lt is realised that the storm water inside the storm drain
may comprise contaminants, such as, for example, metals, such as heavy
metals, organic compounds, and inorganic compounds, metal-organic
compounds, or combinations thereof, as a result of the storm water entering
the storm drain comprises these compounds, and as the result of at least
parts of these compounds not being trapped by the filter unit 2. For the
purpose of further cleaning the storm water in the storm drain by removal or
capturing of contaminants, the ballast unit 6 comprises a solid material, which
may be, for example, slag from production of raw iron by means of a blast
furnace (not illustrated), such as hyttsand. Such material results in efficient
capturing of metals from the storm water. Thus, the hyttsand not only results
in efficient cleaning of storm water by removal of metals such as heavy
metals, but also provides ballast to the device. Hyttsand is, thus, very efficient
as it may provide both efficient removal of contaminants, and provides weight
suitable for providing ballast to the device 1.
10

ln addition to any Cleaning of the storm water by the filter unit and the
solid material in the ballast unit 6, the device may be provided with a sheet of
porous polypropylene 8, at least partially arranged at the surface of the storm
water. The sheet of porous polypropylene 8 may, thus, be particularly efficient
in removing contaminants present at the surface of the storm water, for
example oil, grease or other floating contaminants. Such floating
contaminants may also be removed by means of the filter unit 2 as it may be
arranged in contact with the surface of the storm water. Porous polypropylene
may be an efficient material for removal of oil and grease from the storm
water.
Further, the illustrated embodiment comprises a compartment 15
arranged below the surface of the storm water and provided with porous
polypropylene, and thus contaminants present below the surface may be
removed by means of porous polypropylene.
Figure 2 illustrates a cross-sectional view of a device according to an
embodiment. The discussions above with reference to figure 1 is referred to
with regard to figure 2. Filter unit 2 of the device 1 may be provided with a
plurality of compartments 10, 12, 14, each compartment communicating with
any above or below compartment 10, 12, 14 by being permeable to storm
water, such as by comprising perforations. Typically, storm water flowing into
the storm drain, will enter the filter unit 1 via compartment 10, in which it may
be contacted with porous polypropylene comprised therein (not illustrated)
such that contaminants may be removed from the storm water as the storm
water flows or trickles downwards through compartment 10. The storm water
may then enter compartment 12 via the perforated wall 11, which
compartment 12 may hold, for example, activated carbon (not illustrated)
which when contacted with the storm water may remove contaminants from
the storm water when the storm water is passing through the compartment
after which the storm water may enter compartment 14 of the filter unit 2 via
perforated wall 13, which compartment 14 may hold, for example, slag from
production of raw iron by means of a blast furnace, such as hyttsand, which
when contacted with the storm water may remove metal from the storm water.

From compartment 14, the storm water, now with lower concentrations of
contaminants as compared to prior to having passed the filter unit 2, will be
forvvarded to the storm water of the storm drain.
Although the perforated walls 11 and 13 may be efficient means for
providing compartments 10, 12, 14, it is realised that an embodiment may be
efficient in absence of the walls 11 and 13 such as by the suitable provision of
layers of, for example, porous polypropylene, activated carbon, and hyttsand.
According to one embodiment, the compartments 10, 12, 14 are separated by
means of perforated plastic sheets or layers.
From the above, it is realised that the device of embodiments filters
storm water, for example, as larger particles present in the storm water, such
as gravel, may be prevented from entering the device or may be trapped in
the filter unit, as well as removes contaminants, which may be for example,
compounds or molecules, by binding or capturing the compounds or
molecules to material of the device 1.
According to an embodiment, a device, as illustrated in figure 2, may
be provided with porous polypropylene in compartment 10, 1 kg of activated
carbon in compartment 12, 1.5 kg of hyttsand in compartment 14, and 4.2 kg
of hyttsand as solid material in the metal capturing ballast unit 6, wherein the
floating carrier provides a lifting force corresponding to 8.5 kg.
The above exemplified device 1 and the disclosed embodiments
thereof may by employed with sensors and communication capabilities, not
shown. By employing the device with sensors, conditions of the device itself,
such as the degree of saturation, may be monitored. Additionally, sensors
may be provided at different locations in the storm drain for monitoring
environmental conditions of the storm drain itself, such as the level of storm
water in the storm drain or the amount of water entering the storm drain.
Moreover, the sensors provided on the device or in the storm drain
may be remotely monitored by arranging the sensors in communication with
communication units. Further, remote sensors not present in the storm drain
may be monitored using the same communication units or additional
communication units.

storm drain is disclosed in EP 2 620 562 A1 . The device of the present
invention may advantageously be used in the system and method disclosed
in EP 2 620 562 A1.
Even though the invention has been described with reference to
specific exemplifying embodiments thereof, many different alterations,
modifications and the like will become apparent for those skilled in the art.
