ABSTRACT:
In order to remove certain contaminants such as hydrocarbons and phenols from water, one or more streams of water to be purged are injected into a vessel in which the pressure is maintained low enough to let the water partly evaporate together with the contaminants at or possibly below room temperature. The vapors are exhausted and the remaining water is led off to a reservoir. The vessel may be provided above the water level with baffles or with a particulate filler serving to delay the removal of the vapors therefrom.
