Abstract
The present invention is a method and device for removing radon from groundwater without substantially reducing wellhead pressure. The pressurized radon stripper of the present invention has two principal components: a novel Venturi injector assembly which introduces air into a water process stream from a water source such as a well or the like; and a packed bed contactor which enhances air-liquid contact and serves as a gas-liquid separator. Over two thirds of the radon removal occurs in the Venturi injectors due to the intense gas-liquid turbulence in the throat of the Venturi valve.
