Abstract: Liquid compositions containing solid or semi-solid constituents are resolved by atomizing the liquid to droplets of approximately 0.5 to 6 microns diameter, projecting the droplets at speed of 600 feet per second to sonic velocities into an ambient air entrainment zone wherein the droplets lose water rapidly by evaporation within a short distance, e.g., 30 cm. from their point of ejection, and recovering solids and liquids from the entrainment zone. The entire process is conducted at ambient temperature in the absence of any added heat.
