Abstract
Two basic methods for rapidly fluidizing a plug and two vertical flow filters for carrying out the methods are disclosed. One method comprises injecting a horizontal high pressure plug-breaking-up fluid jet at the bottom portion of the plug for breaking up that portion, injecting another horizontal plug-breaking-up jet at the plug at a predetermined distance above the previous fluid jet for breaking up the next lower portion of the plug, and continuing injecting successive horizontal plug-breaking-up jets, each jet being spaced above the last jet until all of the plug is broken up for rapidly fluidizing the filter media plug. The other method starts fluidizing at the top of the plug and works down. Another method comprises injecting a plurality of horizontal high pressure plug-breaking-up fluid jets simultaneously at the bottom portion of an elongated horizontal plug in a horizontal flow filter for breaking up that portion, injecting another plurality of horizontal plug-breaking-up fluid jets simultaneously at the horizontal plug at a predetermined distance above the previous fluid jets for breaking up the next lower portion of the plug, and continuing injecting successive groups of horizontal plug-breaking-up jets, each group of jets being spaced above the last group until all of the elongated horizontal plug is broken up for rapidly fluidizing the elongated horizontal filter media plug.
