Abstract
PURPOSE: To ensure that a cake adhered to a filter plate can be separated efficiently with a simple construction and operation, by a method wherein a filtrate discharge pipe and an air injection pipe both provided for each filter plate are composed of the same pipe used in common for both purposes, and the separation of the cakes adhered to the filter plates is conducted simultaneously for all filter plates by a single air source.
CONSTITUTION: When the filtration concentration in a filtering and concentrating tank proceeds, concentrated cakes 34 are adhered substantially uniformly onto both sides of each filter plate 10. Then, a filtrate discharge valve 14 is closed and an air injection valve 18 is opened, whereby the pressurized air supplied from the air source 20 can be simultaneously fed to the plurality of filter plates 10. In this case, since part of the filtrate remaining in each of the filtrate discharge pipes 12 and a single conduit 22 flows back into each of the filter plates 10, the filter plates 10 can be back-washed and the separation of the cakes 34 is facilitated.
