    Method and device for purification of stormwater comprising a back-pressure filter (22) which is based on a new way of thinking and is based on the back-pressure principle which works by polluting polluted water from above via a sludge funnel (20). After which the water is led through a channel / pipe (5) down to the lower part of the counter-pressure filter (22) to a distribution chamber (26). Then the water is pushed upwards in the opposite direction through the filter mass (8), to finally have its outlet of purified water in the upper part of the counter-pressure filter (22) below the sludge funnel (20). The filter mass (8) in the new back-pressure filter (22) is based on a mixture of organic material and mineral material. As the new counter-pressure filter (22), the residence time of the water to be treated is many times longer than in previous filters.

    25 30 534 598 it is of the utmost importance to be able to capture these emissions that are toxic to the environment.
    E85 evaporates rapidly in the air and when penetrated into deeper soil layers, evaporation is considerably made more difficult. New EU directives and stricter high environmental requirements for VA have consequences for guideline values, sampling and detailed planning. The Floods Directive is a directive that requires preparation and an action plan to adapt sizing and stormwater facilities for long-term sustainable management of stormwater. The petrol companies are calling for a solution where older oil separators can be supplemented with something so that they can meet the requirements from the authorities for what is emitted from the separators.
    It is therefore an object of the present invention to provide a simple, inexpensive and compact device which provides a solution to the problem described above and which can meet the needs of the market, especially in view of the petrol stations. The back pressure filter is based on a new way of thinking and is based on the back pressure principle which works in the way that polluted water is led from above via a sludge funnel. Where the water is led through a channel / pipe down to the lower part of the back pressure filter to a distribution chamber. Then the water is pushed upwards in the opposite direction through an assltennassa, to finally have its outlet of purified water in the upper part of the counter-pressure filter under the sludge funnel.
    Description The back pressure filter is based on a new way of thinking and is based on the back pressure principle which works in the way that polluted water is led from above via a sludge funnel. After which the water is led through a channel / pipe down to the lower part of the counter-pressure filter to a distribution chamber. Then the water is pushed upwards in the opposite direction through an asslter mass, to finally have its outlet of purified water in the upper part of the back pressure filter under the sludge funnel. The principle of fl fate management is based on the pressure difference in the different water columns. The filter mass in the new back-pressure filter is based on a mixture of organic material and mineral material. An effect of the invention of the new counterpressure filter is that the residence time in the backpressure filter for the water to be treated increases more than eight times than in previous filters. This means that the purification result also increases. The back pressure filter is built with a vertical outer cylinder that is open at the top and has a welded tight bottom. In the center of the cylinder, a vertically open center tube is arranged. The center tube is threaded at both ends. A perforated disc adapted to the inner diurnets of the cylinder has a hole in the center where a pipe sleeve is welded. The disc with the pipe sleeve is threaded into the lower part of the center pipe so that it all ends at a distance adapted to the amount of water above the cylinder bottom. The space between the cylinder bottom and the roundabout forms a distribution core for the water that flows through the back-pressure filter. Another perforated disc adapted to the inner diameter of the cylinder is located in the upper edge of the cylinder. The roundabout has a hole in the center where a threaded nipple is welded. Around the outer edge, the roundel further has a welded ring, the outer diameter of which is adapted to the inner diameter of the cylinder. This disc is threaded into the top of the center tube. To secure the center tube with the discs in place, screw the top disc into its ring, from the outside through the cylinder wall. A cone which in its lower narrow is provided with a threaded sleeve is threaded at the top of the center tube. A sludge funnel is immersed in the cone. The sludge funnel is adapted to the cone, so that there is a certain distance between the inside of the cone and the outside of the sludge funnel, depending on the amount of water which is intended to flow through the back-pressure filter. The sludge funnel is tight at the bottom and up to about a third up the side, after which the side is perforated. A suitable asslter mass is applied between the center tube and the inner wall of the cylinder. The filter mass covers everything between the lower and upper disc. The polluted water is led down into the funnel, where gravel, sludge and smaller particles are separated and settle to the bottom. The water is led further out through the perforation in the upper perforated wall of the sludge funnel and down into the cone and further through the center pipe to the dry dividing chamber. From the drying chamber, the water is then pushed up through the fórlter mass and, after cleaning, fl pours out over the edge of the cylinder and down into the well for further transport to a recipient.
    An embodiment of the invention is described in the following and illustrated in the accompanying drawing, which according to Fig. 1 shows a partially slit view of the back pressure filter.
    Fig. 2 shows how the back-pressure filter is ready for placement in a stormwater well.
    The back pressure filter shown in Figures 1 and 2 may represent the construction applied in the example referred to here. 10 15 20 25 30 534 S58 Method for purifying contaminated water according to figure 1 shows a partially slit picture of the back pressure filter (22) which consists of a vertical outer cylinder (1) which is open at the top and has a welded tight bottom (2) . In the center of the cylinder (1) a vertically open center tube (5) is arranged. The center tube (5) is threaded at both ends. A perforated disc (4) adapted to the inner diameter of the cylinder (1) has a hole in the center where a row sleeve (6) is welded. The perforated disc (4) with the pipe socket (6) is threaded into the lower part of the center pipe (5) so that it all ends at a distance adapted to the amount of water in the amount of solder above the cylinder bottom (2).
    The gap between the cylinder bottom (2) and the perforated disc (4) forms a dry-sharing canister (26) for the water flowing through the back-pressure filter (22).
    Another perforated disc (3) adapted to the inner diameter of the cylinder (1) is located in the upper edge of the cylinder (1). This perforated disc (4) has in the center a hole where a threaded nipple (24) is welded. Around the outer edge, the perforated disc (3) further has a welded ring (23), the outer diameter of which is adapted to the inner diameter of the cylinder (1). The perforated pad (3) is threaded into the upper part of the center tube (5). To secure the center tube (5) with the perforated disc (3) in place, screw the upper perforated disc (3) into its ring (23), from the outside through the wall of the cylinder (1) with screws (25). A cone (9) which in its lower narrow part is provided with a threaded sleeve (7) is threaded at the upper edge of the center tube (5). In the cone (9) a sludge funnel (20) is immersed. The sludge hopper (20) is provided with a handle (13) and adapted to the cone (9), so that there is a certain distance between the inside of the cone (9) and the outside of the sludge hopper (20), depending on the amount of water which is intended to fl desolate through the back pressure filter (22). The sludge funnel (20) is tight at the bottom (1 l) and up to about one third up the side (10), after which the side (12) above is perforated.
    A purpose-built asslter compound (8) is applied between the center tube (5) and the inner wall of the cylinder (1). The filter mass (8) covers everything between the lower perforated pad (4) and the upper perforated pad (3). The contaminated water is led down into the sludge funnel (2) according to the arrow (14), where sludge and smaller particles are separated and settle to the bottom (10). The water is led further out through the perforation in the upper perforated wall (12) of the sludge hopper (20) and down into the cone (9) and further through the center pipe (5) to the distribution core (26). From the drying chamber (26) the water is then pushed, according to the arrows (16) up through the assltennassa (8) to after the cleaning fl spill out over the edge of the cylinder (l) according to the arrows (16) and down into the well for further transport to a recipient. 10 15 20 25 30 534 998 The method for purifying contaminated water according to Figure 2 shows how the pressure medium (22) is ready for placement in a stormwater well. The back pressure filter (22) is suspended in chains (18) to a guide plate (17) which is adapted to the opening of the stormwater well. The guide plate (17) which is provided with a guide funnel (21) directs the storm water towards the mud funnel (20) and holds the structure in place under the well grid through unfolded seams (19).
    The water passes through the back pressure filter (22) as described in Fig. 1 and flows out through the upper perforated disc (3) and further over the edge of the outer cylinder (1). In the embodiment now described, the figures show an example of a back pressure filter with dimensions for a specific water flow. Of course, the back pressure filter can have other dimensions, both vertically and horizontally, as the fate through the back pressure filter is adapted to the prevailing run-off from the catchment area. Likewise, the space for the asslter mass can be varied according to the need for degree of purification. In the embodiment now described, a center pipe is also shown, but the water can also be led down through a channel with varying geometric sections. The invention has been described in accordance with the preferred composition and design, and it is to be understood that certain substitutions and modifications may be made without departing from the spirit. The invention shall thus not be taken as limited to what has been shown and described above, but similar variants are included in the invention tariff and may be considered to be included within the scope of the appended claims.
