摘要： A filtration apparatus includes a vertical column of filter media contained in and defined by a liquid-impervious vessel. A filtrate collection chamber is fixedly and centrally located in the media column. The collection chamber has liquid impervious top and sidewalls and an open bottom, whereby liquid to be filtered and introduced through a feed pipe at the top of the media column passes downward through the media column past the collection chamber and then upward into the collection chamber, is removed through a filtrate collection pipe. The apparatus may include equipment for continuously washing and recycling the filter media, and auxiliary alternatives for increasing the efficiency of the apparatus. Also included is the novel method for practicing the invention, particularly with the novel apparatus.
