A system for removing hazardous contaminants such as radon gas and volatile synthetic organic chemicals from domestic water supplies includes a perforated, horizontally-oriented tray (12) which is baffled to define a curved (e.g., serpentine, spiral) liquid flow path (18). Contaminated water is distributed upon a portion of the tray and flows as directed by the baffles (16) to a downcomer (22) and into a storage tank (68). Air is blown into the storage tank, which is located below the perforated tray, and up through the perforations (14). The forced air causes the water flowing across the tray to froth, and evaporates the contaminants out of the frothing water. The forced air, carrying the volatilized contaminants, is then vented outside the home. |
