摘要： A filtering system (10) includes a filtering apparatus having a filter unit for receiving liquid to be filtered, a receptacle for receiving filtered liquid, and an adapter (14) for coupling the filter unit to the receptacle, and also includes a base (12) having a cradle (26) for receiving the filtering apparatus and a base vacuum delivery port (28). The adapter includes an adapter vacuum receiving port (22) coupled to the vacuum delivery port for driving the liquid through the filter and—as filtered liquid—into the receptacle. The cradle and the adapter have an interlocking mechanism (52, 54) that locks the filtering apparatus to the cradle in a locking position in which the vacuum receiving port is sealingly coupled to the base vacuum delivery port. The base vacuum delivery port has a vacuum valve (30) constituted as a normally-closed valve automatically forced open when the filtering apparatus locks to the cradle.

摘要： A method and system for water-priming carbon micropore filter media using negative pressure. The method includes placing dry filter elements in a polymer bag, applying a vacuum of no more than approximately 33 kPa above zero pressure, and heat-sealing the bag using a heat-set bar; submerging, by a consumer, the vacuum-sealed bag with its the filter elements in water; the filters in the vacuum sealed bag are at least partially submerged, puncturing the bag to form one or more small openings in the bag below the water line. Breeching the vacuum causes the water to flow through the openings into the bag and the filter(s) to equalize the pressure between the water and the previously vacuum environment of the plastic bag, causing the surrounding water to quickly flow into the micro-pores of the filter media, thereby priming the carbon filter for use in the gravity-fed water-purification system.

摘要： A shaker separates components of a slurry. The shaker has a screen with a pressure differential applied to the screen to remove a portion of a slurry. The pressure differential across the screen can be toggled or pulsed. Generally, various types of separators are used to separate liquids and solids. For example, oil-field drilling operations use separators with screens to remove solids from a slurry. One type of apparatus used to remove solids from drilling mud is commonly referred to in the industry as a “shale shaker.”

摘要： Disclosed are an apparatus and a method for reducing a processing liquid consumed for removing bubbles from a new filter unit, and shortening a start-up time when the filter unit is attached in a processing liquid supply passage. The method includes: filling the processing liquid into a new filter unit, decompressing inside of the filter unit into a first pressure atmosphere in order to remove bubbles from the filter unit, boosting a pressure of the inside of the filter unit, flowing the processing liquid into the filter unit from a primary side of the filter unit, and supplying the processing liquid flowing from the filter unit to an object to be processed through a nozzle thereby performing a liquid processing and quickly removing the bubbles.

摘要： A liquid removal apparatus adapted to separate liquid from a composite slurry of liquid and solids. The apparatus includes a movable, permeable membrane having opposing first and second sides. A ‘loaded belt portion’ of the second side is configured to receive the slurry. A permeable membrane support system is configured to provide movable support for the loaded belt portion and includes a transport deck located in contact with the first side of the permeable membrane below the loaded belt portion. The liquid removal apparatus has a housing with a low-pressure chamber in sealing contact with the first side of the permeable membrane. A pressure conditioning system applies a differential pressure via the housing to generate a lower pressure on the first filter belt side than on the second side. The transport deck is located within the low pressure chamber.

摘要： The present invention provides a vacuum filter device including a filter body having two holders on opposite sides of a filter. Each holder contains a closed container in a fluid-tight, sealed relationship. The filter is retained by a compression sealing element that resiliently applies sealing pressure to the upper surface of the filter. The sealing element is maintained in place by a compression element formed of a ring that applies a desired compressive force to the sealing element. The compression element is bonded to a portion of the body to hold it, the sealing element and filter in place and under a compression seal. The invention also can provide for an alignment feature on the compression element that ensures the port is in alignment with the vent of the device. The device also includes a vacuum port communicating with the downstream side of the filter, and hence the filtrate container.
