Abstract: The system and method for determining physical stability of dispersed particles in flowing liquid suspensions is performed by passing a fluid with suspended particulates in a column of filter elements having progressively smaller porosities. The fluid is received by a fluid supply receptacle and then passed through the column of filter elements. The filter elements are arranged so that successive filters are downstream of each other, with successive filters having successively smaller porosities. The porosity of an initial filter element has a sufficiently large porosity to filter a largest particle size intended for detection, and a final filter element has at least a sufficiently small porosity to filter a smallest particle size intended for detection. This results in the successive filters separating successively smaller particles from the fluid. Average particle size and particle count are obtained by removing a mesh filter element and performing SEM analysis on the filtered particles.

Abstract: The devices, systems, and methods of the present disclosure are generally directed to using an increase in gas pressure (e.g., through an increase in heat) to move an actuator that at least partially defines a volume containing a feed fluid in fluid communication with a membrane. As the increase in gas pressure moves the actuator, pressure on the feed fluid in the volume may increase beyond a threshold pressure sufficient to move the feed fluid through the membrane. Movement of the feed fluid through the membrane may reduce a volumetric concentration of one or more components of the feed fluid to form a permeate. For example, the increase in pressure may drive the actuator to increase pressure on salt-water in the volume and, ultimately, move the salt-water through the membrane to form the permeate as part of a reverse osmosis process achieved without the use of a mechanical pump.
