Claim 11:
12. A filter plate assembly, comprising:
a first filter plate having a first side surface;
a second filter plate having a second side surface;
a center plate having an outer surface, a first center plate side surface, a second center plate side surface, and an interior region, said center plate configured to be dropped or forcibly moved between an aligned position and a separated position relative to the first filter plate and the second filter plate,
wherein in said aligned position the interior region is bounded and sealed by the first side surface interacting with the first center plate side surface and the second side surface interacting with the second center plate side surface to form a filter chamber, and
wherein the center plate is configured to drop or move toward or to the separated position and suddenly stopped, wherein the center plate being suddenly stopped in the separated position generates a force that results in removal of filter cake from the interior region of the center plate.
