A porous screen fitted adjacent a vertical plate filter, in close proximity therewith, and means for oscillating or agitating the screen are provided, so that the screen acts to dislodge the filter cake which builds up on the filter plate. A method of dislodging a filter cake is provided which includes oscillation of a screen located adjacent a vertical plate filter having filtering media thereon for filtering fluids, and then continued oscillation of the screen while at the same time expanding the filtering media toward the screen and washing the filtering media with water.
