Abstract: The present invention relates to an apparatus for filtering a liquid through a movable filter bed consisting of granular material, with continuous scavenging of the bed material and having the characterizing functions as follows:the filtering takes place in that liquid from a central inlet passes outward and upward through the filter bed.the filter bed in operation moves continuously downward, and the bed material is renewed continuously by supply to the upper portion (A) of the filter.the separation of impurities in the liquid takes place substantially in the central portion (C) of the filter and to a small extent in the portions located closest to the outlet.the washing of polluted bed material takes place in several steps, the first one thereof by fluidization of the material in the lowermost portion (D) of the filter, and the last one with liquid and air in the upper portion (A) of the filter.polluted bed material is drained in the lower portion of the filter together with transport liquid to a sand washing equipment located outside the filter, from which equipment transport liquid is returned to the lower portion (D) of the filter and washed material of the bed is transported to the upper portion (A) of the filter to be finally washed and distributed over the entire surface of the filter bed.in the apparatus, liquid can be filtered, in which the permissible size of the impurities is limited only by the dimension of the inlet conduit. Owing to the function of the apparatus the risk is eliminated that outgoing filtered liquid is polluted by release of dirt from the filter bed or from bed material returning to the bed after washing.

Abstract: An apparatus for cleaning a metal filter comprises a cleaning bath having a predetermined size and connected to a cleaning solution tank, a jig which is vertically elevatable and horizontally slidable in the cleaning bath and to which the metal filter is fixed, a nozzle mounted so that a discharge hole thereof is faced upward in the cleaning bath, and a controller which controls supply and blocking of a cleaning solution from the cleaning solution tank to the cleaning bath, controls supply and blocking of compressed air or the water to the nozzle, controls movement of the jig, and controls filling or discharging of the water into/from the cleaning bath. The controller controls the movement of the jig and selectively controls the supply and blocking of the water, the cleaning solution, and the compressed air, and the draining of the cleaning bath according to predetermined logic.

Abstract: A cleaning method according to the present invention comprises mounting the metal filter on a jig that is vertically elevatable and horizontally slidable in a cleaning bath so that the opening is faced downward, descending the jig so that a first nozzle installed in the cleaning bath enters the opening, injecting a predetermined amount of water and a cleaning solution into the cleaning bath so that the metal filter is immersed, spraying compressed air through the first nozzle to discharge bubbles of the compressed air toward an inner surface of the metal filter, draining the cleaning bath, spraying water through a second nozzle to remove the cleaning solution from the metal filter, and spraying the compressed air through the first nozzle to dry the metal filter. An apparatus for cleaning a metal filter is also disclosed.

Abstract: The present invention relates to a multistage fiber filtering apparatus capable of selectively filtering depending on turbidity of raw water, in which a first filtration mode where the raw water passes through a fiber ball medium, a second filtration mode where the raw water passes through a fiber yarn medium, or a third filtration mode where the raw water passes through both of the fiber yarn medium and the fiber ball medium may be selectively operated.

Abstract: Method and apparatus are provided for treating and removing particulate matter from fluid or treating and removing fluid from a recoverable particulate matter from fluid circulating into, through and out of an industrial operation, and for washing a disposable cartridge filter used therein. The influent fluid is maintained at a flow rate such that the differential pressure across the cartridge filter is no greater than 10 psi to prevent the buildup of non-porous filter cake. A pressure detecting mechanism and method is also provided to detect the amount of deposited particulate matter inside the cartridge filter, so that an operator can determine whether the cartridge filter should be taken out to remove or recycle the deposited particulate matter.

Abstract: A screen decanter for decanting liquid from a reservoir, comprising at least one rack comprising screens and baffles forming the sides of a cavity; a frame attached to the screens and baffles and providing a barrier so that liquid cannot pass from outside into the cavity without passing through the screens; a patterned perforated drain pipe inside the cavity and leading to an opening through which liquids may drain out from the cavity. The pattern of the openings counteracts the hydrostatic head within the rack such that flow through the screens is uniform at all depths of immersion in the liquid reservoir. Preferably, the screens have a porosity of about 50 micrometers.

Abstract: A static screen has a plurality of screening bodies and a plurality of aeration devices downstream of the screening bodies. Each aeration device is associated with a set of one or more of the screening bodies. Each aeration device may be a pulsing aerator. The pulsing aerators do not all release air at the same time. Each screening body works through periods of dead end filtration separated by backwashing events. The backwashing events comprise introducing a slug or pulse of air into the bottom of the screening body. Flow through the static screen continues at all times because the screening bodies are not all backwashed at the same time. The static screen may be used to remove trash from water flowing to an immersed membrane unit. Alternatively, the static screen may be used to provide primary wastewater treatment.
Abstract translation: 静电屏幕具有多个筛选体和在筛选体下游的多个曝气装置。 每个曝气装置与一组或多个筛选体相关联。 每个曝气装置可以是脉冲曝气器。 脉冲曝气器并不能同时释放空气。 每个筛选机构通过反冲洗事件分离的死端过滤时间。 反冲洗事件包括将痰液或脉冲的空气引入筛选体的底部。 任何时候，通过静态屏幕的流动将继续，因为筛选机构并不都是同时进行反洗。 静态屏幕可用于从流入浸入的膜单元的水中清除垃圾。 或者，静态屏可用于提供初级废水处理。
