摘要： A method and a plant for the treatment of water or wastewater having impurities by filtration of the water through two granular media filter stages of the moving bed type operated in series. The method includes the steps of feeding the water/wastewater as a first influent to first stage granular media filters; filtration of the first influent in the first stage granular media filters to produce a first effluent; feeding the first effluent as a second influent to second stage granular media filters; and filtration of the second influent in the second stage granular media filters to produce a second effluent. The second stage granular media filters are operated with intermittent washing of the granular filter media.

摘要： A pilot filter system for monitoring water quality in a water treatment system is disclosed. The pilot filter system includes: a filter vessel containing a downward-moving bed of filtration media, the filter vessel being fluidly connected to the water treatment system such that sample influent water from the water treatment system flows into the filter vessel and over the bed, wherein the filter vessel has a filtrate outlet port through which some filtrate is discharged; a media recycle conduit fluidly connected to the filter vessel; and a media recycler for circulating a mixture of water and used filtration media through the media recycle conduit to a point upstream of the bed in the filter vessel.

摘要： An apparatus for removing impurities from water and/or wastewater and a method of installing a fluid distribution system in the apparatus. In the most preferred form of the invention, the fluid distribution system is an air scour system for directing air through the filter bed to assist in cleaning of the filter bed to remove impurities trapped in the filter bed during a service run. In the most preferred form, the method of installing the fluid distribution system in the filter bed is performed by imparting a force to the filter bed to permit the fluid distribution system to be installed in the filter bed without removing media. The fluid distribution system is preferably configured to permit the fluid distribution system to be readily installed in the filter bed and at an optimum orientation.

摘要： A filtering process for and apparatus separating air bubbles and granular filter medium from a filtrate contaminated by the filter medium and bubbles when passing through a filter bed formed by the filter medium for treatment of a suspension or liquid solution, a gas being passed through the filter medium in contact therewith, includes providing a treated filtrate zone (3) above the filter bed (2), collecting the treated filtrate in the filtrate zone, conducting granular filter medium from the filter bed (2) upwardly through a conveying pipe (4) to a position above the filter bed and thereafter downwardly through a washing apparatus (5) from which the filter medium is precipitated onto a plate (11) above the filter bed. Treated filtrate flows through a separate chamber formed by a cylinder (12) around the washing apparatus (5) and then upwardly through the lower end of the washing apparatus and outwardly through the upper end of the washing apparatus and thereafter leaves the system through an overflow outlet pipe (7). The filtrate leaves the system through a separate filtrate outlet (8). The filtrate flowing downwardly through the separate chamber functions as the washing liquid and flows at a rate sufficiently low for separation of gas bubbles in the chamber therefrom. The filtrate washing liquid flowing upwardly through the washing apparatus (5) flows at a rate sufficiently low for separating the downwardly conducted granular filter medium.

摘要： A deep bed upflow filter (10) for removing suspended solids from an influent stream to provide a clean filtrate, comprising an upright vessel (12) having a vertical axis (14), top and bottom ends (16,18) and contiguous upper (20), lower (22), and intermediate (24) regions between the ends. The upper region contains filtrate (26) up to a first elevation (28) and an outlet (30) for drawing the filtrate out of the vessel. The intermediate region contains particulate filter media (32) for removing the suspended solids from influent moving upwardly through the media as the media, dirtied with solids, moves downwardly into the lower region. The lower region is generally tapered (36) inwardly toward the vessel bottom and contains dirty media (34) that has moved downwardly from the intermediate region. Influent is introduced (44) between the intermediate and lower regions, and the dirty media is collected (46) at the bottom and transported (50) to a regenerative washing compartment (52). A portion of the reject flow (64 ) from the wash compartment is delivered (72,74) to the dirty media in the lower region of the vessel and another portion (72,78) is delivered to the area (46,48,50) where the dirty media is collected and transported. This latter portion is preferably introduced into a collection conduit (46) through a pipe (130) having a concentric inner tube (140) by which air is injected to fluidize and move the mixture of air, dirty media, and reject water in the conduit (46) toward an airlift (48,148).
