Abstract
Two vertical flow filters for carrying out various methods for rapidly fluidizing a plug are disclosed. An apparatus comprises a vertical elongated granular media filter having vertically spaced apart plug-breaking-up jets on one side from top to bottom for ejecting high pressure fluid horizontally at the plug for fluidizing it, one portion at a time, starting either at the top or the bottom of the filter. The second apparatus comprises a horizontal cylindrical elongated granular media filter having vertically spaced apart groups of jets on both sides, the jets of each group being in horizontal rows on two opposite sides whereby each successive horizontal row, including both rows on each horizontal plane through the filter, breaks up its respective portion of the plug, starting either at the bottom and working up or starting at the top and working down.
