Abstract

A multiple effect distillation chamber includes a plurality of separate distilling chambers and a drain chamber at a downstream end of the distilling chambers. The drain chamber functions to create a vacuum to draw volatile gases and impurities collected at the end of the distilling chambers into the drain chamber. The drain chamber cools the volatile gases via cooling water, whereby the cooling water and volatile gases are not mixed during the cooling process, such that the cooling water may be recycled and reused. The drain chamber may include two heat exchangers, each receiving cooling water from a separate water source. Utilizing separate water sources in conjunction with the dual heat exchangers of the drain chamber enables the flow rates of the cooling water sources to be adjusted to enable the disposal of waste water from the distiller at any desired temperature without affecting other functions of the distillation system.
