Filed: 1980-07-25
Abstract: PURPOSE: To make the rate of dehydration of each filter plate uniform, and to improve dehydration efficiency by applying pressure from the inlet side of a filter body and the opposite side thereof thereby maintaining the liquid pressure in the filter body uniform over each filter plate.  
     CONSTITUTION: Water to be treated is pumped 19 to a feed hole 24A via a feed pipe 22 and a force feed pipe 23A and to a feed hole 24B via a branch point 22B and a force feed pipe 23B, respectively. The liquid to be treated force fed into a filter body 6 passes through the central holes 3A of filter plates 2 and passes through filter cloths 25, by which it is separated of solids. The treating water having undergone the solid-liquid separation flows through the conduit holes 3C in the clearances between the filter cloths 25 and the filter plates 2 and flows from the body 6 down into a receiving plate 18. Since the water to be treated is fed to the filter body 6 from both ends with partition wall plates 2C as a boundary, there are not much differences in the distributions of filter pressure between the filter plates 2 and the filter plates 2 adjacent to the plates 2C, and the amounts of the cake stuck to the filter cloths 25 of the eespective plates 2 are approximately uniformalized. Upon ending of the solid-liquid separation, the cake is dislodged from the filter cloths 25 by a vibrating machine.
