Vacuum filter apparatus and method for recovering contaminated liquid |
摘要 |
A filter system employs a pressure differential to draw liquid from a first liquid vessel through a filter media to a filtered liquid chamber. A pressure assembly generates a reduced pressure in the chamber. One embodiment of the filtration apparatus includes a liquid vessel above a filtered liquid chamber. A laterally extending fluid-pervious support forms a septum between the liquid vessel and the filtered liquid chamber. The support can be a perforate plate and supports filter media. The apparatus includes a wheel element mounted in spaced relation to the perforate plate and at least a portion of which is located in the vessel. An indexing mechanism, illustratively employing a pneumatic actuator selectively rotates the wheel element for indexing the media.
