    The device works as follows,
    Water under pressure from the tank 11, containing dissolved air and lyelectrolyte, is supplied to the inner tank 2 through conduit 33 In the distribution pipe 13, in the form of a rectangle, there are openings for water release to tank 2a. The distribution pipe 13 is installed in the upper central part of the tank 2 directly Below the surface of the water in tank 2, before it flows into the outer tank 1, the tiny air bubbles in the water coming out through the versts in pipe 13 are attached to flakes that carry particles in water as it is poured into the reservoir 1, and then the flakes float to the surface of the water in the reservoir 1, forming a layer of sludge on it "
    In the center of the device, above the internal reservoir 2, is located a windrower 5, intended for receiving the sludge collected by the bucket 7 and discharged from it through the pipe 7a. the inner tank 2, its upper end is connected to the funnel 5 and passes through the tanks 1 and 2; On pipe 7a near the main bucket. 7. An auxiliary bucket 76 is installed.
    The conical bottom of the inner tank 2 in the center is connected to a bottom pipe 29, through which heavy solid sediments, such as sand, are accumulated in the bottom of the inner tank.
    To clean the surfaces of the filter layers, the Za serves as a suction bun “- ker 20 suspended from platform 6 by a rod 34 connected to an electric motor 25 mounted on a platform"; The rod is surrounded by a housing 35 attached to the platform, Internal - 5 th hopper volume 20 s By means of the pipeline 36, the vacuum is connected to the “-to4o som 26, which is also installed on the platform 6 and to which the exhaust pipeline 28 is connected, the outlet to the“ - 0 ”is connected to the internal volume of the tank 2" The electric motor 25 lowers the bunker 20 to each filter "- layer Pro and lifts it from this layer. The dimensions and shape of the bunker 5 20 at its bottom are such that the bunker in its lowest position fits snugly to the surface of the corresponding layers of sand. Moving the booth 20 relative to the fixed 0 casing 35 is possible due to the use of plastic material, for example measures of elastic plastic for pipe "- wires 36"
    The rotation of the platform 6 is controlled by a chick switch 38 mounted on the platform and having a drive lever 40 running outside and down from the platform. The micro switch 38 is connected to the electric motor 24 and is pre-assigned to turn on and off the latter. To the wall of the tank 1 is attached a plurality of protruding parts (rods or rods) spaced apart around the circumference, assigned to contact the switch actuating lever 40 as the platform rotates. The number and relative position of the rods determines the number and The position of the filter layers of the Za layers, and the operation of the electric motor "- body 24, is thus controlled by a switch and a timer. The vacuum bunker 20 is lowered only onto the advanced filter layers during each complete rotation of the platform 6, as described . For monitoring, timer 37 has a pre-settable pulse switch of known type

    When the device is in operation, the initial clarified water is sent to the apparatus through conduit 14 and is premixed with a flocculating substance, such as alum, introduced through conduit 17, and this mixture enters tank 2 through nozzle 16 In tank 2, floccules (flakes) are formed. as the water moves in a spiral to the top of the apparatus, while the water is thoroughly mixed with flakes, thereby improving the deposition of particles that pollute the water obliquely. The mixture of partially clarified water with dissolved air and the floccule polyelectrolyte enters reservoir 2 through feed conduit 33 and is discharged at the top of the reservoir through a perforated pipe 13, where the flakes with entrained particles are attached to air bubbles released by this method of releasing water from the 13C pipe. the mixture flows into tank 1, and the flakes with adhered particles are carried with air bubbles onto the liquid surface in tank 1, forming a layer of floatable sludge on the liquid surface. As the platform 6 rotates, scoop 7 collects sludge and unloads t in the funnel 5, from where it is discharged through pipe 23 for appropriate disposal of
    Most of the contaminated particles are removed from the unclarified water using the described flotation and sludge removal process. Then, as unlighted water continuously enters the tank 2, the water in tank 1 with residual flakes and contaminated sediment flows to the bottom of the tank and passes through a row of sand filters in the annular chamber 30, after which it is removed through the pipe 21 as clear water
    As sludge accumulates on the surface of sand filters, the flow of liquid through the sand decreases. To maintain the required flow of liquid through the system, the sand in each is filtered, the layer is periodically cleaned. This is done by lowering the vacuum bunker 20 with predetermined intervals On each filtering layer after stopping the platform 6 When the vacuum pump 26 is running, water is sucked through the filtering
