Abstract (en)
[origin: EP0318074A1] Tire marks on airport runways can form an impenetrable layer which prevents water from draining away when there is heavy rain. To remove this rubber deposit a device is employed comprising one or more nozzles which are connected by means of a pipe to a source for pressurized water, a circulation system which is movable with the nozzles and which is at least provided with a water tank (30), a pump unit (32) connected thereto for raising the water to very high pressure, a hood (5) with suction line (8) fitted round the nozzles, filter means for removing solids from the water extracted from the hood, and a return pipe to the tank (30). In order to get a very effective removing of almost all particles from the water the device is fitted with a cyclone (9) for the extraction of air, a filter (15) for coarse lumps connected to the cyclone, at least one bag-type filter (22, 23) for particles larger than 3 mu m and an activated carbon filter (28) for small particles.
