摘要:
The present invention is aimed at treating rainwater in a combined sewer system, while enabling removal of a majority of pollution substances even if a large amount of entering rainwater. The invention relates to a rainwater-treating apparatus in a combined sewer system, said apparatus comprising a plurality of upward flow type high-speed filter vessels each having a layer of a floating filter medium, a common treated water vessel which is located at upper faces of said high-speed filter vessels and is adapted to collect treated water from the high-speed filter vessels, a used wash water vessel which collects used wash water from said high-speed filter vessels, a rainwater inflow channel for distributing the entering rainwater into upper portions of the high speed filter vessels, and rainwater inflow portions for flowing downwardly the rainwater distributed from the rainwater inflow channel under the respective floating filter media of the filter vessels.
摘要:
A filter unit for removing leukocytes from a leukocyte-containing suspension by passing the suspension through a filter unit. The filter unit may comprise a main filter for blocking the leukocytes and a post-filter for preventing leakage of the leukocytes having a higher median pore size than the main filter and placed downstream of the main-filter.
摘要:
The invention relates to an oil system, in particular a hydraulic oil system or a lubricating oil system, comprising a sensor for monitoring the impurity content of the oil in the oil system, the sensor detecting a value which is correlated with the impurity content. A particularly cost-effective construction is achieved, if the sensor is configured as a turbidity sensor which measures the turbidity of the oil, which has been caused by the impurity content.

A screen system used in fluid channels has emergency discharge doors. The emergency discharge doors are located within the debris plate of the bar screen system and can be opened, as needed, to prevent fluid from overflowing should the grid screen become obstructed. The emergency discharge doors are located within rectangular openings in the debris plate in which the doors sit flush with the debris plate when closed. The emergency discharge doors can be opened manually, when needed, with handles that are preferably located at the top of the screen system. Lifting the handles releases the locking pins that keep the doors in place, allowing the doors to open freely in response to the fluid pressure on the upstream side of the screen system.

A continuous flow slurry cleaning method, apparatus and system including a filter portion and a mud re-circulation manifold for receiving partially filtered slurry, containing the slurry and mixing the slurry with liquid ready for use and thereby enabling a continuous, re-circulating flow through the filter portion. The continuous flow slurry cleaning apparatus and system further include a tank for storing and delivering liquid ready to be used by a drilling machine. The continuous flow slurry cleaning method, apparatus and system further includes a mud circulation/agitation system for keeping solids in suspension and for mixing additives along with the liquid ready for use and thereby modifying the makeup of the liquid ready for use.
摘要:
Method and arrangement for filtering particles out of a liquid, in which the liquid containing particles is supplied to a sedimentation tank (12), and the liquid is made, by means of hydrostatic liquid pressure prevailing in the tank, to flow through a filter member (18) on the shell surface of a drum (14) mounted in the tank (12). When the liquid in the tank has risen to a predetermined level above the drum (14) as a result of clogging of the filter member (18), cleaning of the filter member (18) in situ in the tank is initiated.
摘要:
For separating solids contents from a pulp, the pulp is concentrated in a filter device by intense movement up to a predetermined solid matter content. In the filter device, the dynamic pressure and Venturi effects are utilized to support the filtering process. During the discharge of the filtrate, pulp is supplied to keep the filter device in filled condition. The concentrated pulp is batch-wise transferred into a pressing chamber in which the discharged batch is mechanically pressed-out. The pressing cake generated thereby is mechanically comminuted.

A carded nonwoven filter media comprising one or more layers of core-sheath fibers wherein the sheath portion of a fiber is bonded to one or more adjacent core fibers is disclosed. In a preferred embodiment, the nonwoven filter media includes an antimicrobial fiber component.
摘要:
A method of operating a plant for filling containers by moving a liquid such as water through an apparatus with at least one portion for receiving the liquid before it is filtered and at least one portion for receiving the liquid after it is filtered, so that the liquid moves from at least an upper area of apparatus to lower area of the apparatus to be transferred to bottles or other containers.
摘要:
A deep bed liquid treatment apparatus and process in which the liquid and a granular media is periodically agitated to create a liquid-media slurry, and outflow of the liquid and entrained contaminants is induced through a separator having an inner diameter screen with openings sufficiently small to prevent the escape of media granules. A rotor is rotated within the separator to create turbulent flow at the screen to dislodge the granules drawn onto the screen openings.
