Patent number: 5685976Abstract: 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 which is baffled to define a curved (e.g., serpentine, spiral) liquid flow path. Contaminated water is distributed upon a portion of the tray and flows as directed by the baffles to a downcomer and into a storage tank. Air is blown into the storage tank, which is located below the perforated tray, and up through the perforations. 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.Type: GrantFiled: May 8, 1995Date of Patent: November 11, 1997Assignee: North East Environmental Products, Inc.Inventor: Bruce L. Lamarre

Patent number: 4869832Abstract: A radon removal system includes a packed mass transfer material aeration column and is sized to fit within a single story of a residential building. A residential water supply that is naturally contaminated with radioactive radon gas is connected to the top of the column. The water is preferably distributed across the top of the mass transfer packing by a coarse mist spray nozzle. The water splashes down through the packing and collects in a holding tank at the bottom of the column. Air, blown up through the column packing, comes into contact with the radon-laden water, and evaporates the radon out of the water. The radon-laden air is then vented outside the home.Type: GrantFiled: July 13, 1987Date of Patent: September 26, 1989Assignee: North East Environmental Products, Inc.Inventor: Bruce L. Lamarre
