Abstract

PURPOSE: To enlarge the pressing power of belts while suppressing their tension, by alternatively laminating several sheets of endless belt material to form the upper and lower filter cloth belts in a manner such that each of them has a multi-layered structure at least at its contact surface part.
CONSTITUTION: Sludge with a flocculant is fed into a sludge-coagulating vessel 5, agitated in the vessel 5 to form coagulated sludge, and then fed onto the upper surface of a lower filter cloth belt 2. The fed sludge is dewatered by its own weight at the front side part of the upper stretched portion of the lower filter cloth belt 2, press-dewatered by the upper and lower filter cloth belts 1, 2, gradually clamped into a dewatering portion 13 defined by the belts 1, 2, and then wound around a press roller group 3 located at the dewatering portion 13 to dewater the sludge by pressure. A filtrate formed by the dewatering is let fall from the lower stretched portion of the lower filter cloth belt 2, collected in a water-collecting trough 7 and drained to the next process. Dewatered cake is dropped on a belt conveyer 6 and carried to the next process.
