An aqueous solution of NaCl was atomized by irradiating ultrasonic of 1.6 MHz and was brought into contacted with dry air to remove water for the enrichment. The generated mist was send to a cyclone to classify droplets into large ones and smaller ones along with water vapor. The mixture of small droplets and water vapor was cooled to condense in the condenser. Effluents from the cyclone and condenser were weighed and analyzed to determine the NaCl concentration. Gas velocity at cyclone inlet has a significant effect on the NaCl concentration and the amount of recovery of both effluents. With increasing gas velocity, the NaCl concentration of cyclone effluent increased due to the evaporation from the larger droplets that consist of the feed solution. While the effluent of condenser enriched with water. The enrichment of NaCl aqueous solution was attained by ultrasonic atomization with the mist classification using a cyclone. The gas velocity at cyclone controlled the water separation from the feed aqueous solution.
