ABSTRACT:
Liquid treating apparatus especially useful for water purification, including an output section and an input section interconnected at their tops by a closed condensation chamber. The input section includes raw liquid supply and return columns, opening at their bottoms into a raw liquid supply open to the atmosphere, and the output section includes treated liquid supply and return columns open at their bottoms into a treated liquid container also open to the atmosphere.
Treated liquid is cooled and circulated in the output section to produce and maintain negative pressure at one end of the condensation chamber, and raw water in mixed liquid and vapor form is supplied by aspiration in the input section, the vapor phase passing through the condensation chamber, and the liquid phase being used to drive the pump which causes the circulation in the output section. Several embodiments of the invention are shown.
