Frame Filter

Plate & Frame Filter The plates are covered with filter cloth. The plates are hung on a pair of horizontal support bar and pressed together during filteration to form a water tight closure between plates. The press can be closed manually, hydraulically or by a motor drive. The slurry to be processed is pumped between the plates where the filterate is collected along a channel system or through individual laps at each of the plates. The cake between the plates is then washed until it is free of the mother liquor. The discharge of solids is released by opening the closing device.
