ABSTRACT:
A dual-belt method and apparatus for dewatering a water laden cake of material through the use of multiple primary dewatering rolls is disclosed. A pair of porous belts containing filter cake disposed between the belts are wrapped around a first and second primary roll so that the belts circumscribe more than a 180.degree. arc of each roll. The pressure applied to the belts, that is, to the filter cake, is greater on the second roll than on the first roll.
