Abstract
A liquid separator to extract liquid, usually water, from a water-solid mixture. The liquid separator has a housing with an inlet and an outlet separated by a liquid extraction chamber. The housing sidewalls defining the extraction chamber are porous, and are preferably comprised as a plurality of spaced apart rails or slats. The spacing between the rails provides a porosity for extraction of water. The rails are movable inwardly and outwardly relative to the housing in order to vary the volume of the extraction chamber. Bias means are provided that normally bias the rails inwardly of the chamber. A water-solids mixture is pumped through the chamber and tends to expand the chamber against the force of the biasing means. The combination of effects upon the subject mixture is to cause water extraction through both the squeezing by the slats and the friction occassioned by the dewatering of the subject mixture.
