Separator for removing impurities, especially smaller particles, from rain water. It comprises a first reservoir (2) and a second reservoir (6). The first reservoir (2) performs the function of removing the heaviest portions of the impurities, but is also provided with a lamellar device (4), wherein
Separator for removing impurities, especially smaller particles, from rain water. It comprises a first reservoir (2) and a second reservoir (6). The first reservoir (2) performs the function of removing the heaviest portions of the impurities, but is also provided with a lamellar device (4), wherein small drops and impurities of the rain water may be combined to larger impurity aggregates. The second reservoir (6) is divided into a first chamber (6a) and a second chamber (6b), said chambers communicating with each other. A tube (5) provided with perforations (5′) is arranged above the lamellar device (4), through which rain water containing impurities is able to flow from the first reservoir (2) and into the first chamber (6a). The first chamber (6a) is provided with a filter (9). In this way, a more efficient purification of rain water than using the known separator is provided.

The invention claimed is: 1. Separator for removing impurities, especially smaller particles, from rain water, said separator comprising a first reservoir having an inflow and a second reservoir having an outflow, and where the first reservoir performs the function of removing big size impurities,
The invention claimed is: 1. Separator for removing impurities, especially smaller particles, from rain water, said separator comprising a first reservoir having an inflow and a second reservoir having an outflow, and where the first reservoir performs the function of removing big size impurities, a lamellar device provided in the first reservoir, wherein small amounts of impurities in the rain water may be combined to a major amount of impurities, whereby the second reservoir is divided into a first chamber and a second chamber, said chambers separated by a vertical baffle communicating with each other beneath said baffle, the first chamber provided with a horizontally-arranged filter separating the first and second chambers, characterized in that a tube provided with perforations is arranged above the lamellar device, through which rain water containing impurities is able to flow from the first reservoir and into the first chamber and then exit the second chamber after having passed the filter. 2. Separator as claimed in claim 1, characterized in that the filter is arranged at the transition between the first chamber and the second chamber. 3. Separator as claimed in claim 1, characterized in that the filter is adapted so as to be easily replaceable. 4. Separator as claimed in claim 1, wherein the filter has a plate construction, with the plates arranged vertically. 5. Separator as claimed in claim 1, further comprising a first pump installed in the second chamber, the pressure side of said pump connected to an outflow pipe provided with spray openings, said outflow pipe leading into the first reservoir through at least one wall. 6. Separator as claimed in claim 5, further comprising a second pump installed in the first reservoir, for evacuating rain water containing impurities from said reservoir. 7. Separator as claimed in claim 1, wherein the filter has a plate construction, with the plates arranged vertically and comprising a material selected from at least one of polyvinyl chloride and polyethylene. 8. Separator as claimed in claim 7, wherein the filter has a filter plate construction, with a distance between individual filter plates in a range of 0.5-30 mm. 9. Separator as claimed in claim 8, wherein the filter has a filter plate construction, with a distance between individual filter plates in a range of 5-10 mm. 10. Separator as claimed in claim 7, wherein the filter has a filter plate construction, with the filter arranged predominantly horizontally, and with the filter plates arranged predominantly obliquely and in series. 11. Separator for removing impurities, especially smaller particles, from rain water, said separator comprising: a first reservoir having an inflow, in which the first reservoir performs the function of removing big size impurities; a second reservoir divided into a first chamber and a second chamber, said chambers separated by a vertical baffle communicating with each other beneath said baffle, and the second chamber having an outflow; a lamellar device being provided in the first reservoir, the lamellar device causing small amounts of impurities in the rain water to collect; a filter arranged at the transition between the first chamber and the second chamber; and a tube with perforations arranged above the lamellar device, through which rain water containing impurities may flow from the first reservoir and into the first chamber, wherein after having passed the lamellar device the water passes from the first reservoir to the second reservoir through the perforations, and after ending of a rainfall, flushing the filter results in flushing the particles from the filter and back to the first reservoir, permitting discharge of the flushing water containing the smaller particles. 12. Separator as claimed in claim 11, wherein the discharge of the water containing the impurities permits discharge to a sewer. 13. Separator as claimed in claim 11, wherein the filter has a plate construction, with the plates arranged vertically and comprising a material selected from at least one of polyvinyl chloride and polyethylene, the filter adapted for easy replacement. 14. Separator as claimed in claim 13, wherein the filter has a distance between individual filter plates in a range of 0.5-30 mm. 15. Separator as claimed in claim 13, wherein the filter has a distance between individual filter plates in a range of 5-10 mm. 16. Separator as claimed in claim 13, characterized in that, the filter has a predominantly horizontally position with the filter plates arranged predominantly obliquely and in series. 17. Separator as claimed in claim 11, wherein the filter has a predominantly horizontal position. 18. Separator as claimed in claim 11, further comprising a first pump installed in the second chamber, the pressure side of said pump connected to an outflow pipe provided with spray openings, said outflow pipe leading into the first reservoir through at least one wall. 19. Separator as claimed in claim 18, further comprising a second pump installed in the first reservoir, for evacuating rain water containing impurities from said reservoir.
