Abstract

A method and system (10) for treating feedwater includes evaporating a portion of the feedwater in a first evaporation chamber (78) so as to separate water vapor from the remaining feedwater. Droplets of the remaining feedwater are dispersed into a stream of hot air produced in a second evaporation chamber (26). The droplets evaporate and solids in the feedwater precipitate. The precipitated solids are collected in the lower section (30) of the second evaporation chamber (26). Water vapor discharged from both evaporation chambers (78, 26) can be treated in a cyclone separator (56) to remove residual solids therefrom. The cleansed water vapor output from the cyclone separator (56) can be condensed to recover clean water. Dry solids can be discharged from the second evaporation chamber (26) and the cyclone separator (56) for recovery.
