摘要： The invention relates to a filtering apparatus including, inside a filtering tower (1), a filtering section (r), a liquid collecting section (7) and a liquid feeding section (e). The liquid feeding section (e) includes a diffuser (A) attached to an upwardly oriented orifice (5a) formed at a leading end of a liquid feeding pipe (5). The object is to provide an apparatus which allows use of the existing filtering tower without its enlargement and which allows uniform falling of the filtering liquid over the substantially entire top surface of the filter medium layer, thus making it readily possible to maintain the flatness of the top surface of the filter medium layer even when light-weight medium is employed, thereby to allow the filter medium layer as well as the entire filtering apparatus to achieve their desired filtering performance. The diffuser (A) includes a damping portion (k) for damping the momentum of the liquid discharged from the orifice (5a), a first discharging portion (8) for upwardly discharging the liquid damped by the damping portion (k), a second discharging portion (9) for laterally discharging the liquid damped by the damping portion (k), and a third discharging portion (10) for downwardly discharging the liquid damped by the damping portion (k), said first, second and third discharging portions being stacked one on another from the top to the bottom in the mentioned order.

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： A filter device for removing contaminants from liquid flowing therethrough comprising a vessel having an inlet for providing a contaminated liquid flow into the interior thereof and an outlet through which filtered liquid can exit the vessel. A screen means contained within the vessel supports a filter media thereof. A pump has a suction and discharge located within the vessel and respective to the screen whereby the filter media can be fluidized and thereby cleaned without removing the media from the vessel. The scrubbing action transfers the contaminants from the filter media into the scrub water and thereby enables the contaminants to be removed from the vessel by discharging the scrub water therefrom.

摘要： A flume distribution system includes a distributor having a stationary lower portion and a removable upper portion. The lower portion defines a duct which is in fluid communication with a flume and at least one underdrain lateral. The lower portion also includes an apertured end wall which abuts one of the underdrain laterals at a lateral inlet, and a stop is disposed within the duct and spaced from the end wall. The duct receives a removable orifice plate which is adapted to pivot between a slant inactive position abutting the stop and an upright active position restricting the aperture in the end wall. During backwash operations, water is introduced to the flume and enters each duct in the lower portion of the distributor, and the pressure of the incoming water causes the orifice plate to pivot from the slant position to the upright position, reducing the cross-sectional area of the aperture in the end wall and thereby regulating the velocity of backwash flow from the flume into the lateral inlet. The orifice plate is held in place by a pressure differential across the plate, but it returns to the slant inactive position during filtration when flow through the system is reversed. The upper portion of the distributor may be removed as needed to place different sized orifice plates within the ducts for obtaining uniform backwash distribution.
摘要翻译：水槽分配系统包括具有固定下部和可拆卸上部的分配器。下部限定与水槽流体连通的管道和至少一个缺口侧向。下部还包括一个有孔的端壁，其在侧向入口处邻接一个下划线，并且止动件设置在管道内并与端壁间隔开。管道接收可移除的孔板，该孔板适于在靠近止挡件的倾斜非活动位置和限制端壁中的孔口的直立活动位置之间枢转。在反冲洗操作期间，将水引入水槽并进入分配器下部的每个管道，并且进入的水的压力使得孔板从倾斜位置枢转到直立位置，从而减小横截面积的端壁中的孔径，从而调节从水槽进入侧向入口的反冲洗流速。孔板通过板上的压差保持在适当位置，但是当流过系统的过程中，孔板返回到倾斜的非活动位置。可以根据需要去除分配器的上部，以将不同尺寸的孔板放置在管道内以获得均匀的反冲洗分布。
