摘要： A filter cartridge (10) containing resin beads (140) for purifying fluids such as water and chemicals has a cylindrical housing (5) with an interior compartment containing a fixed septum (150) and a moveable piston-like septum (130). The resin beads are packed between the fixed septum and the moveable septum. The moveable septum is displaced upstream to account for expansion of the resin beads while the flow of the fluid through the filter cartridge causes the upstream septum to maintain a packing pressure on the resin beads. The downstream fixed septum will preferably have a cone-like shape.

摘要： This invention relates to a novel intermittent slow sand filter and a method of using the intermittent filter. More particularly, this invention pertains to a novel slow sand filter which remains effective, even when intermittently operated, and which can be periodically cleaned without disturbing the action of the intermittent filter. A slow sand filter apparatus comprising: a container having an upper portion and a lower portion; a water inlet in the upper portion of the container, the water inlet being connected to a supply of water; a filter material filling at least the lower portion of the container, the filter material having a top surface below the water inlet; a schmutzdeuke layer on the top surface of the filter material; a water outlet in the lower portion of the container below the top surface of the filter material; and a water level maintenance device in the upper portion which maintains water in the upper portion of the container at a maintenance level above the top surface of the filter material, the maintenance level being a balance between (1) a water maintenance level that is sufficiently deep that water falling from the water inlet onto the top of the water in the container does not significantly disturb the schmutzdeuke layer; and (2) a water maintenance level that is sufficiently shallow that oxygen from the air above the water level can diffuse through the water and reach the schmutzdeuke layer so that the schmutzdeuke layer is maintained in living condition even when there is no flow of water through the water inlet.

摘要： The invention concerns a device for intake of water into a granular material bed filter such as filters used for water treatment for eliminating suspended materials comprising means for injecting water and air through the filter bed and a channel for evacuating filtered water and a trough for evacuating wash-water. The invention is characterised in that it comprises two superposed overflow levels: a lower level (6) for intake of filtered water and a higher level (7) for intake of dirty wash-water, means being provided for shifting from one overflow level to the second overflow level, the channel (8) evacuating treated water and the trough (9) evacuating dirty water after washing being superposed.

摘要： A compact, rapid upflow deep media filter (10) for removing suspended solids from a liquid flow, which includes: a filter casing (12) having a liquid inlet port (16), a liquid outlet port (18), and a filter bed (26) composed of a volume of granular filter media (24) and located between the inlet port and the outlet port; and a screen (32), selectably movable between a first operative position and a second operative position within the filter casing, whereat in the first operative position the screen maintains the filter bed in a packed state so as to permit filtration therethrough of a liquid flow from the inlet port to the outlet port, and whereat in the second operative position the screen does not maintain the filter bed in a packed state such that in the presence of a liquid flow from the inlet port to the outlet port the volume of filter media expands so as to enable separation therefrom of suspended solids accumulated during filtration of the liquid flow therethrough.
摘要翻译：一种用于从液体流中除去悬浮固体的紧凑型快速向上流动的深度介质过滤器（10），其包括：具有液体入口（16）的过滤器壳体（12），液体出口（18）和过滤床（26），其由一定体积的颗粒状过滤介质（24）组成并且位于所述入口和出口之间; 以及可在所述过滤器壳体内的第一操作位置和第二操作位置之间可选择地移动的筛网（32），其中在所述第一操作位置中，所述筛网将所述过滤床保持在挤压状态，以允许过滤通过其中的液体流从入口到出口，并且在第二操作位置，筛网不将过滤床保持在压缩状态，使得在存在从入口到出口的液体流的情况下，过滤介质的体积膨胀以使其能够与在其中流过的液体过滤期间积聚的悬浮固体分离。
