摘要： A particulate media filter employing a continuous media backwash, designed to promote mass or plug flow of the filter media within a filtration vessel and to eliminate areas of stationary media particles. The filter vessel contains a filter bed moving downwardly, countercurrent to an upwardly-moving solids-contaminated influent or feed stream. The contaminated liquid is cleaned by its passage through the filter bed, and is removed as filtrate from a location in the vessel above the top of the filter bed. The downwardly-moving filter bed media becomes progressively more contaminated, and is removed from the filtration stream near the bottom of the filter vessel for cleaning and recycling into the filter stream. A frustoconical skirt-like perimeter feed profile is disposed on the interior of the vessel, surrounding a conical center feed profile, under which may be placed a coaxial center feed pipe. A single, large, substantially unobstructed annular channel for countercurrent flow of influent and filter media is defined between the two profiles. The influent is introduced into the filter vessel between the perimeter feed profile and the wall of the vessel, and under the center feed profile via separate feed distribution channels fed by a common feed header, subsequently entering the filtration stream from underneath the profiles.
摘要翻译： 采用连续介质回洗的颗粒介质过滤器，设计用于促进过滤介质在过滤容器内的质量或活塞流动，并消除固定介质颗粒的区域。 过滤器容器包含与向上移动的固体污染的流入物或进料流逆流的过滤床。 被污染的液体通过其通过过滤床进行清洁，并从过滤床顶部上方的容器中的位置作为滤液除去。 向下移动的过滤床介质逐渐被污染，并且从过滤器容器底部附近的过滤流中除去，用于清洁和再循环到过滤器流中。 截头圆锥状的裙状周边进给轮廓设置在容器的内部，围绕圆锥形的中心进给轮廓，在该锥形中心进给轮廓下可以放置同轴的中心进给管。 在两个轮廓之间定义一个单一的，大的，基本上无障碍的环形通道，用于逆流流入和过滤介质。 流入物在周边进料轮廓和容器壁之间以及在中心进料轮廓下通过由共同进料头进料的分离的进料分配通道引入过滤容器中，随后从型材下方进入过滤流。

摘要： The invention relates to a gravity filter comprising a housing (1), a cavity (3) with a base in the form of a cone, an inlet for a liquid to be cleaned, with tubes (4, 5, 6) for discharging the cleaned and cleaning liquid, a filtering medium (7) placed in the housing (1), a structurally combined unit, fixed along the vertical axis of the housing (1), which in turn contains an airlift (8) with an air tank (10) that is configured in communication with a compressed air source, a cleaning element (9), which preferably comprises two parts, and which is fixed over the airlift (8), wherein the cleaning element (9) has one compartment with a zigzag channel (14), and wherein the cleaning element (9) has, especially concentrically located, compartments (15, 16), the internal and the external ones, and a tube (4, 5, 6) for cleaning liquid drainage, in communication with the latter; furthermore, the filter has distribution units (12, 11) for liquid and for the filtering medium. The filter is characterized in that it is further equipped with a vibration aerator (20), which is inserted or configured to be inserted into the zigzag channel (14) of the cleaning element (9), especially of its lower part (13) of the structurally combined unit, and/or with a means for pressure and speed reducing of the upward flow of the cleaning liquid in the internal compartment of the cleaning unit, especially its upper part, and/or with a means for providing the airlift (8) vibration.

摘要： The present invention is a dual-stage, gravity continuously-backwashed filtering system for filtering contaminants from wastewater. This filtering system has a first sand-filter unit that is loaded with wastewater influent. The filtering sytem has injection points for coagulation chemicals and disinfection chemicals. The first sand-filter unit is connected in series to a second sand-filter unit of similar design. The first sand-filter unit is made up of large-grained sand, the second sand-filter unit fine-grained sand. The second sand-filter unit receives its influent from the effluent weir of the first sand-filter unit. The reject water from the second filter unit is re-introduced into the influent that is fed to the first filter unit. The reject matter from the first filter unit is passed to waste.
