Abstract
The invention provides a filter plate of increased size which includes a reinforcing bar which subdivides the inner face of the plate into distinct drainage areas. The drainage areas are in liquid flow communication with each other via recess formed in the reinforcing bar. The plate is provided with raised spacing elements which are positioned in a special pattern to provide uniform deflection across the plate when the filter press is under pressure. The plate is further provided with a staggered, offset pattern of drainage ribs which enhances filter cloth support, increases plate strength and improves liquid flow around the spacing elements.
