Abstract: A suspension is delivered to a filter bed comprised of granular filter medium in a continuously working filter at the lower part of the bed and is then permitted to flow upwards through the bed. With the intention of optimizing the capacity of the filter, the suspension is now guided into a central region of the bed. The suspension is divided from this region into at least two specific proportional quantities which are each led from the filter bed in a respective ring-shaped pattern at mutually different heights in relation to the extension of the bed, these ring-shaped patterns having different diameters and each being adapted to the extension of the filter medium in the direction of the diameter.

Abstract: An apparatus for filtering liquids, such as fiber suspensions or polluted water, includes a hollow rotating filter body adapted to receive the liquid to be filtered within the body. A plurality of guide members are attached to the filter body and distributed around the latter to receive cloudy filtrate penetrating the filter body at the descending side. A basin is arranged at the descending side of the filter body to collect cloudy filtrate poured from the guide members. As a result, the cloudy filtrate is prevented from mixing with the clear filtrate.

Abstract: A method and a plant for the treatment of water or wastewater having impurities by filtration of the water through two granular media filter stages of the moving bed type operated in series. The method includes the steps of feeding the water/wastewater as a first influent to first stage granular media filters; filtration of the first influent in the first stage granular media filters to produce a first effluent; feeding the first effluent as a second influent to second stage granular media filters; and filtration of the second influent in the second stage granular media filters to produce a second effluent. The second stage granular media filters are operated with intermittent washing of the granular filter media.
