Abstract:
본 발명은 밸러스트수 여과장치에 있어서, 필터부를 수용하는 밸러스트수 여과장치 내에 동심원 방향으로 필터엘리먼트를 설치하고 여과장치 하단에서 밸러스트수를 유입시켜 여과장치 내부의 필터엘리먼트를 통과시켜 여과를 수행하면서, 구동부가 여과장치의 하단에 위치한 흡입부를 회전시켜 필터엘리먼트와 연결시키고 차압에 의해 필터 내부의 이물질을 포함한 역세수를 배출하는 밸러스트수 여과장치에 관한 것이다. 특히, 본 발명은 상기 구동부를 하우징의 하부에 위치시켜 하우징 내에 더 많은 필터엘리먼트를 수용하여 밸러스트수 처리에 적합하도록 여과효율을 높이고, 역세수의 배출라인 상에 배압방지탱크를 두어 배출라인 상의 배압이 증가하는 것을 방지하는 것을 특징으로 하는 배압형성을 방지하는 캔들 타입 밸러스트수 여과장치에 관한 것이다.
Abstract:
A monitoring system (10) is disclosed for monitoring the condition of a filter (16) filtering a gas or liquid. Using various sensors, the permeability of the filter is monitored on a continuous basis. A significant increase in permeability, decrease in permeability or rate of change of permeability can lead to an indication of filter failure, such as rupture, leakage, loading and unloading. The system can be monitored by a computer and monitored from a remote location through phone lines and Internet computer systems.
Abstract:
A filtering installation comprises two cartridge filters (34) each containing a filter cartridge (7) formed of an inner filtering element (9) and of an outer filtering element (10). The filtering elements (9 and 10) are separated by a flow channel (13) and are arranged on a housing plate (5). The cartridge filters (34), respectively the filter cartridges (7) are connected in parallel to a feeder channel (35). The flow channel (13) of each filter cartridge (7) opens out in a reflux channel (38). The housing plate (5) is welded to the casing wall (6) by the welding seams (33) and the two parts are rigidly connected. The passage section of the inlet opening (3) is larger than the passage section of the evacuation channel (13). Thereby, it is possible to obtain a hydrostatic pressure up to 10 Kg/cm2, and therefore a liquid flow rate in the order of 250 m3/h.
Abstract:
Systems and methods are provided by which filtration media may be backwashed more effectively. In especially preferred forms, the present invention is embodied in a filter cartridge assembly which includes generally tubular filter cartridge (16) and a tubular surge chamber (20) physically attached to one end of the filter cartridge (16) at one end thereof. The tubular surge chamber (20) thus provides for an available stand-by additional volume of liquid immediately adjacent the filter cartridge (16) so that, upon backwashing, the additional volume of liquid serves to direct a concentrated wave of energy into the filtration media.
Abstract:
In critical filtration applications, filter cartridges (200) are employed to replace ion exchange resin precoat filters to minimize the waste produced. The filter cartridges (200) which are housed in a multiple cartridge filter housing (300) with an inlet (320), an internal baffle plate (330) which defines an upper chamber (340) and a lower chamber (350), are backwashed with all gas via a gas inlet (410) and the liquid in the filter housing (300) provides an active scouring effect as a result of the high levels of turbulence produced. The baffle plate (330) is provided with ports (360) to receive the cartridges (200). Chamber (350) is provided with a filtrate outlet (380). The liquid, with entrained debris from the filter, is minimized in volume.
Abstract:
Eine Filtervorrichtung mit einer Mehrzahl von Filterelementen (21), die in einem Filtergehäuse (1) mit einem Filtereinlass (11) für zu filtrierendes Fluid und einem Filterauslass (13) für das gefilterte Fluid aufnehmbar sind, wobei während des Betriebs der Vorrichtung zu mindest eines der Filterelemente (21) zum Abreinigen seiner wirksamen Filterfläche mittels einer Rückspüleinrichtung rückspülbar ist, die eine Drucksteuereinrichtung (7) zur Unterstützung der Rückspülung beinhaltet, ist dadurch gekennzeichnet, dass die Filterelemente (21) jeweils in einem Elementgehäuse (30) aufgenommen sind, dass die Elementgehäuse (30) mit den den Filtrationsvorgang wahrnehmenden Filterelementen (21) mit ihrem einen offenen Ende (33) mit dem Filterauslass (13) fluidführend in Verbindung stehen, und dass das Elementgehäuse (30) des jeweils rückspülbaren Filterelements (21) mit seinem einen offenen Ende (33) ausschließlich an die Drucksteuereinrichtung (7) angeschlossen ist.
Abstract:
A filter assembly for use in filtering stormwater includes a bottom including a boss that includes a rib extending laterally along an inner surface of the boss. The rib includes a locking portion that mates with a corresponding locking portion on a peripheral surface of a connection to an outlet conduit for securing the bottom to the connection thereby inhibiting rotation of the bottom relative to the outlet conduit. A center tube is secured to the bottom using a locking mechanism that inhibits relative movement between the bottom and the center tube. The center tube is in communication with an opening in the bottom and a hood is secured to the center tube. A filter medium is located between the hood and the center tube.
