Abstract:
Increasing demand for freshwater has been necessary for the development of the urban community. Saline water is one of the problems for urban society in coastal areas. Separation techniques to distilled water from saline water were performed by using many different kinds of systems. In recent years, many kinds of technology had been developed to convert saline water into freshwater with various methods and apparatus. Ultrasonic atomization is one of the methods to generate very narrow water droplets on atmospheric pressure and ambient temperature. This project has experimented to observe the performance of new technology within the water purification process from saline water and it’s assisted by an ultrasonic humidifier for the humidification process. It has been performed a miniature technology which utilized a commercial ultrasonic humidifier with a power rating of 10 watts and resonance frequency 0f 1,65 MHz. Utilization of carbonactivated foam had been conducted to gain the perf
ormance of the humidification and dehumidification process. This work had been also analysed the measurement of the production of freshwater by its quality and quantity. The quality of the freshwater has been indicated by total dissolved solids (TDS) or salt concentrations of the output of this technology and also the number of output freshwater flow rates as their quantity. It has been measured about 2750-2850 ppm and the rate of freshwater production about 60-86 ml/h by a single unit of ultrasonic humidifier. It also indicated that influence of carbon activated foam to gain water output rate.
