    Abstract: An accumulating tank serving as a filter for an overflowing swimming pool, and more particularly a device for filtering water from an overflowing swimming pool using an accumulating tank acting as a gravity filter. The accumulating tank (1) serves as a prefilter, and a filter for water from the pool; it filters by decantation through a filtering mass (8, 9). It comprises apparatus for cleaning the filtering mass (8, 9) by reversing the direction of water current (F2), so as to cause to overflow the volume of water from the accumulating tank (1) and recover the impurities by overflow of the used water into a gutter (15) and evacuation for emptying by a pipe (24).

    Abstract: A method of and an arrangement for thickening of suspensions includes filtering of a suspension through candlelike filter elements in a filter container, backwashing the filter elements individually without interrupting the filtration process by applying pressure impulses of gaseous backwash medium to the pressure elements in a direction opposite to the filtration direction, wherein the gaseous backwash medium forms a gas chamber over the filter elements separated from the suspension fluid and having an adjustable pressure.

    Abstract: The present invention relates to an apparatus for filtering a liquid through a movable filter bed consisting of granular material, with continuous scavenging of the bed material and having the characterizing functions as follows:the filtering takes place in that liquid from a central inlet passes outward and upward through the filter bed.the filter bed in operation moves continuously downward, and the bed material is renewed continuously by supply to the upper portion (A) of the filter.the separation of impurities in the liquid takes place substantially in the central portion (C) of the filter and to a small extent in the portions located closest to the outlet.the washing of polluted bed material takes place in several steps, the first one thereof by fluidization of the material in the lowermost portion (D) of the filter, and the last one with liquid and air in the upper portion (A) of the filter.polluted bed material is drained in the lower portion of the filter together with transport liquid to a sand washing equipment located outside the filter, from which equipment transport liquid is returned to the lower portion (D) of the filter and washed material of the bed is transported to the upper portion (A) of the filter to be finally washed and distributed over the entire surface of the filter bed.in the apparatus, liquid can be filtered, in which the permissible size of the impurities is limited only by the dimension of the inlet conduit. Owing to the function of the apparatus the risk is eliminated that outgoing filtered liquid is polluted by release of dirt from the filter bed or from bed material returning to the bed after washing.

    Abstract: An apparatus for cleaning a metal filter comprises a cleaning bath having a predetermined size and connected to a cleaning solution tank, a jig which is vertically elevatable and horizontally slidable in the cleaning bath and to which the metal filter is fixed, a nozzle mounted so that a discharge hole thereof is faced upward in the cleaning bath, and a controller which controls supply and blocking of a cleaning solution from the cleaning solution tank to the cleaning bath, controls supply and blocking of compressed air or the water to the nozzle, controls movement of the jig, and controls filling or discharging of the water into/from the cleaning bath. The controller controls the movement of the jig and selectively controls the supply and blocking of the water, the cleaning solution, and the compressed air, and the draining of the cleaning bath according to predetermined logic.

    Abstract: A cleaning method according to the present invention comprises mounting the metal filter on a jig that is vertically elevatable and horizontally slidable in a cleaning bath so that the opening is faced downward, descending the jig so that a first nozzle installed in the cleaning bath enters the opening, injecting a predetermined amount of water and a cleaning solution into the cleaning bath so that the metal filter is immersed, spraying compressed air through the first nozzle to discharge bubbles of the compressed air toward an inner surface of the metal filter, draining the cleaning bath, spraying water through a second nozzle to remove the cleaning solution from the metal filter, and spraying the compressed air through the first nozzle to dry the metal filter. An apparatus for cleaning a metal filter is also disclosed.
