Filter press-type filtering apparatus using rigid filter element |
摘要 |
There is disclosed a filtering method comprising using a filter-press-type device in the chambers whereof filtering means divide a compartment for material to be filtered from a filtrate-collecting compartment, compressing the possibly-washed material to be filtered by reducing the volume of the compartments for material to be filtered, discharging washing solute and filtrate which have passed through the filtering means, and dismantling said filter-press. The method makes use of filter means which are resistant and undistortable under the method conditions, and retains the filtering means in a relative position to the filtering chamber axis which is identical during all the filtering steps.
