    2G 25 30 533 979 In the following, the invention is illustrated by means of application examples with reference to the accompanying drawings, of which Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 6 Figure 6 Figure 7 shows as a 'schematic section fi gur of an alterbasin with carrying pontoons , the carrying capacity of which is dimensioned to realize the method according to the invention; schematically shows an air suction apparatus used to perform a step of the method according to the invention; shows schematically a side view of an apparatus with which the method according to the invention can be realized utilizing wind power e.g. for water purification at beaches; shows a device according to Figure 3 schematically seen from the front; shows an apparatus according to another embodiment of the invention, in which replaceable filter bags 12 on the filter bottom 1 of the basins 2 are used, whereby the suction interval of the filter cloth bottom 1 is considerably extended; shows a device with which the method according to the invention can be realized in large watercourses, and shows as a schematic section a device of yet another embodiment with which the method according to the invention can be carried out efficiently.
    Figure 1 depicts an alter basin 2 with a filter cloth 1 on the bottom, through which cloth water with a content of blue-green algae is led to collect blue-green algae on the filter cloth bottom 1. Surface water with blue-green algae is sucked with a Dump 3 (Figures 3-6) to the filter basin 2. The filter basin 2 is supported by 10 15 20 25 30 533 979 3 pontoons 9, the load-bearing capacity of which is so dimensioned that the bottom of the filter basin 1 lies below the water level 10, as the basin 2 contains the water load of the water fed by the pump. The lower picture of Figure 1 shows the water level 11 inside the filter basin 2 during pumping, the water level 11 being slightly higher than the surrounding water level 10. The sides of the filter basin 2 can be water-impermeable or, like the bottom, provided with water-permeable filter cloth. The filter cloth 1, on the other hand, is based on the construction of the basin 2, which is net-shaped or grid-shaped or a perforated plate. The upper picture of the fi gure 1 shows how the 1lter bottom 1 rises above the water level 10, when the selection: - is not pumped into the basslter basin 2. The blue-green algae are sucked with a suction device, which is depicted in i- ”lgur 2, from the collection basin filter - cloth 1. The air vacuum cleaner has a suction nozzle 4, a suction and transfer hose 5 and an intermediate layer forming collecting chamber 6, on the bottom of which the blue-green algae 8 accumulate at the same time as air is diverted from the chamber 6 via the ascending drain pipe 7.
    In its simplest form, the device realizing the method according to the invention is realized so that the basins 2 are two to the number side by side and they are fed with blue-green algae containing water with a pump. When the basin 2 is filled with algae water, the pump jet is moved to the empty basin cleaned of algae. In this arrangement, the basins 2 can be firmly anchored to the pontoons 9, as the buoyancy of the pontoons 9 is dimensioned according to the previously stated method. The bottom of the filter basin 2 with the filter cloth 1 during the pumping is below the water level 10 of the watercourse and during the suction the filter pool 2 rises by itself (when the water load generated by the pumping is drained) to a level where the screen bottom 1 lies above the water level basin 10. i-' construction can be simplified by using an alteration principle, where at least two basslter basins 2 algae water are pumped in turn, the suction being carried out from the terlterbassin 2 to which water is not pumped. 10 15 20 25 30 533 979 4 In an advantageous embodiment of the invention PUFWPGS algVafïe-n fi "fi lïefbas' the bed with a propeller pump 3, which can be driven by a winch rotor 13 (Figures 3 and 4) of Savonius type. The rotor can be used for cleaning small or filter-delimited watercourses from algae, so diaphragm pumps, which are cheaper than propellerPumDaf, can also be used, since a lot of time is available for cleaning a small area.With the method according to the invention, the water lifting force is very small , whereby pumping of even large amounts of water very large effects are not required.An electric propeller pump can generate a flow of 5000 l / second.
    By using e.g. of a vessel towed basin compartments, which are fed by several propeller pumps 3, as shown in Fig. 6, large areas of water can be purified.
    In all embodiments, the water flows through the cloth 1 back to the sea or lake and the algae remain on the cloth 1.
    In the embodiment according to Figure 5, the need for the cleaning suction of the cloth bottom 1 can be reduced by using replaceable cloth bags 12, which connect to the feed water pipe 14 by means of an ON / OFF valve. By regulating the valves, it is then always possible to interrupt the water supply to the collecting basin 2, the lower part 12 of which is to be replaced and / or the bottom of the cloth 1 of which is to be sucked clean.
    In all embodiments, the accumulation of algal water at the pump 3 can be promoted with V-shaped expanding collecting blade 15. The pumping can advantageously be carried out with a pump 3, which is placed partially or completely below the water level 10 during the pumping. In addition to a propeller pump and diaphragm pump, other types of pumps, such as vane, screw, hose, etc. can also be used. pumps come into play. The catamaran-type pontoon vessel, which carries the whole, may be statlonal or it may move with its own power source or the vessel may be towed or propelled forward. 10 15 20 25 30 533 979 5 The cleaning suction of the bottom of the alter basin can be performed manually, as shown in Figure 2, but the movement of the suction nozzle can of course be automated.
    A suction nozzle 4 can, if necessary, be used for bottom cleaning of more than one filter pool. Likewise, the pump 3 can be arranged on a separate pontoon for movement to a position in front of the current basslter basin, which is to be filled. In the embodiments according to Figure 6, a separate pump 3 has been arranged for each basslterbassängrad. Likewise, each pool row can have its own suction device, the nozzle of which moves in turn on the bottom of each separate pool 2.
    Alternatively, the suction can also be carried out so that the bottom 2 of the cloth of the basin forms a uniform cloth conveyor, which is shifted periodically or continuously towards the suction compartment. Such an embodiment is depicted in Figure 7.
    In it, clean cloth 1 is fed from a roller 17 to the bottom of the filter basin 2, which is below the ambient water level 10 and at which the level 11 of the pumped water is above the level of ambient water. From the bottom of the filter basin 2, the filter cloth 1 is moved to the suction point 4, which is above the water level 11 of the filter pool. The guide roller 20 in front of the air suction 4 presses excess water from the filter cloth, which water flows back to the pool 2 or watercourse.
    From the air suction 4, the filter cloth 1 is moved to a machine-rotatable roller 19.
    The air suction is made more efficient by blowing through 4a of the filter cloth. The suction and blowing can be realized by using a fixed suction beam 4 and a fixed blow beam 4a, between which the filter cloth 1 is pulled to the roller 19. The filter cloth 1 is displaced on rotating rollers 8 at the bottom of the filter basin 2. The filter cloth 1 is displaced across the flow basin the direction of flow of the water and / or the alter basin transporting the direction of travel of the vessel. The reference number 21 indicates the end of the water supply pipe, from which the pumped water is discharged into the basin 2. With this arrangement the required lifting height of the water can be minimized and the amount of flow maximized in relation to the pumping effect. The height difference h between the water levels 10 and 11 produces a pressure difference which forces water through the displacement speed of the filter cloth 1. The filter cloth 1 is kept suitable, so that blue-green algae do not have time to clog it and the flow in the basin 2 is preserved. As the mass of water in the basin 2 is for the most part below ambient water level 10, the pontoons 9 can correspondingly be less dimensioned and the return flow of the basin 2 can take place calmly, whereby the risk of clogging of the cloth 1 decreases and it is easier to clean with suction. the 2 sides of the base bed and the bottom of fi lterduk 1 are formed and the gables consist of water-impermeable walls.
    As a cloth can be used e.g. geotextiles, used in earthworks. Such a cloth is typically one made of thin polypropylene or polyester fibers, which is well water permeable, but so dense that even very small particles get stuck in it. In addition, such a cloth is cost-effective, whereby also large areas of it can and it can be replaced with a new one, the filtration capacity and / or the water permeability has been weakened.
