Abstract: A suction device for a disc filter includes at least one suction bar per discoid filter body and a suction slit designed for suctioning the impurities of the filter cloth, as well as a suction pump for suctioning the impurities. The suction bar is movable radially from the axis of rotation of the disc filter.

Abstract: A device for cleaning and/or suctioning pile fibers for pile fabric filtration can be brought into a fluid connection with a suction source and includes at least one suction slot. The device for cleaning and/or suctioning has structure for mechanically cleaning, restoring and profiling the pile fibers. The structure increases the cleaning effect and simultaneously realigns the pile fibers and thus restores the pile fibers layer.

Abstract: An adsorbent and a metering unit are used in a facility for processing liquids for removing dissolved organic and/or inorganic substances. The water-soluble metering unit, which contains an adsorbent, is metered into the liquid to be treated, in order to remove dissolved organic and/or inorganic substances depending on the amount of dissolved organic and/or inorganic substances to be removed, wherein the adsorbent is released. When metered into the liquid to be treated, the metering unit disintegrates or disperses and releases the adsorbent which, on account of the then extremely large surface area, can bind high quantities of dissolved organic/inorganic substances.

Abstract: A method for removing dissolved organic substances in liquids with a superfine adsorbent includes the method steps of measuring the concentration of dissolved organic substances in the liquid, adding pulverized activated carbon in the submicron range according to the measured concentration of organic substances to the liquid to be treated and mixing the powdered activated carbon with the liquid to be treated, leaving the mixture for a sufficient residence time to allow the powdered activated carbon to adsorb the dissolved organic substances in the liquid, and removing the pulverized activated carbon from the liquid by filtration.
