A filter press for separating solid components from liquid components of a slurry. The filter press includes a compression system coupled to a stationary pressure plate of the filter press. The compression system includes at least one electrically operated compression actuator having a planetary screw assembly, and a transport system coupled to a displaceable pressure plate of the filter press. The transport system includes at least one electrically operated transport actuator having a rack and pinion drive assembly. The compression system rigidly connects to the transport system so as to form, for each respective pair of compression actuators and transport actuators, a common actuator link which extends linearly from the stationary pressure plate to the displaceable pressure plate along the longitudinal dimension. A retrofitting kit for a filter press, a method for replacing an existing compression and transport system for a filter press and a method for controlling a filter press are set forth.

A handling system of a subframe forming part of a filter plate frame assembly in a horizontal filter press of a tower type is provided. The handling system includes a supporting structure and a suspension arrangement. The supporting structure includes a first longitudinally extending rail and a second longitudinally extending rail which are interconnected with a support surface configured to slidingly support a subframe when being moved in and out of the filter plate frame assembly. The suspension arrangement is arranged in a first end portion of the supporting structure. The suspension arrangement is configured to allow the supporting structure to be selectively and removably connected to the filter press in an area adjacent a filter plate frame assembly. Further, a method of performing maintenance of a subframe is provided, which method involves the use of such handling system.

A filtration apparatus that can include a filtering device can be configured as a pressure filter. The filter device can facilitate rapid cycling of cake discharge so that the cake formation and discharge sequence can complete itself in a short period of time (e.g. a few seconds, no more than 30 seconds, no more than 10 seconds, up to 18 seconds, less than a minute, less than 3 minutes, etc.).
