Abstract
An improved continuous process and apparatus for treating an impure liquid to produce purified liquid, particularly, water, the process having an electrically activating a thermoelectric module to provide a first heated surface and a cooler surface; feeding the impure liquid to the first heated surface to produce vapour of the liquid; and transferring the vapour to the cooler surface to effect heat transfer to the cooler surface, the improvement being directing a minor portion of the vapour to the cooler surface to maintain the cooler surface at a temperature at or near the boiling point of the liquid; and transferring a major portion of the vapour to a condenser remote from the module to effect heat transfer and condensation of the vapour to produce the purified liquid and collecting the purified liquid from the condenser. The process is continuous in that it does not need to be intermittently stopped, or require auxiliary cooling of the module. Preferably, the heat from the condenser is transferred to pre-heat the impure liquid feed.
