    Abstract: フィルタエレメント組立体は、少なくとも2つの円筒形で同心に配置されているフィルタ媒体スリーブを有し、それぞれのスリーブは、スリーブの一端で入口プレートに接続され、他端で端部閉プレートに接続されている。 開口が入口プレート内に設けられ、これにより、ろ過する液体は、フィルタスリーブとフィルタスリーブとの間の環状スペース内に入り得る。 端部閉プレートは、ろ過されない液体がスリーブとスリーブとの間の環状スペースから流出するのを阻止して、液体がスリーブの多孔性媒体を通過するように強制し、ろ過が行われる。

    Abstract: A filter candle element which is mounted in depending manner in a pressure container has a support body and a filter tissue which covers the support body and has at least one impermeable portion so as to prevent the depositing of a continuous filter cake. Through provision of a plurality of impermeable portions, the filter cake is divided into several pieces which do not obstruct their removal. The impermeable portions are obtained by spraying of synthetic material onto the filter tissue. These filter candle elements are especially suitable for alluvial filters of large dimensions.

    Abstract: A filter element assembly has at least two cylindrically shaped and concentrically arranged filter media sleeves (11, 12) each connected at one end thereof to an inlet plate (13) and each connected at the other end to a closed end plate (20). Openings (16) are provided in the inlet plate (13) to permit entry of liquid (A) to be filtered into the annular space between the filter sleeves (11, 12). The closed end plate (20) prevents flow of unfiltered liquid from the annular space between the sleeves so as to force the liquid through the porous media of the sleeves to effect filtration.

    Abstract: PROBLEM TO BE SOLVED: To provide a filtering system for separating the solid phase in a slurry from the liquid phase.
    SOLUTION: The method of forming a filter cake from a slurry comprises the steps of: feeding the slurry into a filter housing that includes a plurality of vertical filter elements; pressing the slurry into the filter housing against the filter elements resulting in (i) a filtrate passing through the filter elements and exiting out an exhaust port of the filter housing; (ii) forming a solid cake on the filter elements; feeding a wash liquid into the filter housing while draining out the slurry by opening the slurry drain valve; closing the slurry drain valve and then continually feeding wash liquid through the cake and into the filter tube; stopping the feed of wash liquid; introducing a gas and draining out the wash liquid by opening a bottom drain valve; stopping the gas flow and opening a drain valve to exit most of the gas and remaining wash liquid; opening the bottom cake discharge valve; and back pulsing by a gas to break and to release the filter cake from the filter elements.
