A filter press is disclosed for separating solid components from liquid components of a slurry. The filter press includes side beams and a plurality of filter plates oriented at right angles to the longitudinal direction of the side beams. The filter plates are adapted to move along the side beams. A stationary end is arranged on one end of the side beams and a movable head is adapted to transport the filter plates along the side beams. The filter press includes a press system adapted to exert a closing pressure on the filter plates to press the filter plates against each other. The press system further includes at least one electrically driven actuator adapted to generate an axially directed force on the filter plates by means of the movable head. The disclosure also relates to a method for separating the solid components from the liquid components of a slurry.

The present invention provides a system and methods for filtering fluid using filter papers, stationary paper, cloth sheets or any other porous material. In one embodiment, the present invention uses the lateral flow direction along the porous sheets, instead of conventional vertical flow direction, for the removal of bacteria and particle contamination in the range from nanometers to millimeters. The pore sizes in the filter media along the lateral direction are modulated by controlling the compression of the porous sheets, instead of conventionally designing filters with different pore sizes. The lateral flow fluid filter system is scalable simply by increasing the feed area, feed length, and the number of porous sheets. The invention presents a universal fluid filtration system for wide range of applications such as water purification, food processing, chemical industry, oil and gas industry, and biological applications.
