Abstract: A belt filter press-type apparatus receives a partially dewatered "cake" comprising a liquid/solid suspension which has been processed by conventional liquid/solid separation equipment; the apparatus removing additional moisture from the cake. The apparatus comprises two liquid-permeable belts which are driven by belt driving means along respective predetermined paths. The belts, however, share respective portions of their paths substantially in common. The cake is sandwiched between the two belts and driven through the common portions of the respective belt paths. The combination of the belts with the the cake interposed therebetween meanders around a plurality of rollers which create tension and pressure on the belt and the cake, thereby driving part of the liquid content out of the trapped suspension.
