<p>A water-purifying apparatus, which is especially adapted to reduce the radon content of radon-contaminated water, comprises a reactor tank (1) for treating the radon-contaminated water, a radon-releasing means (2) arranged in the upper part of the reactor tank to receive water from a first pump (3) adapted to supply water from a source of water containing radon-contaminated water, the water from the radon-releasing means accumulating in the reactor tank, an inlet duct (4) extending between the first pump and the radon-releasing means, an outlet duct (6) from the reactor tank, the outlet duct being connected to a water consumption system, and a radon-gas outlet (9) from the reactor tank. In a mixing means (11), water from the first pump (3) is mixed with water from the reactor tank (1) with the aid of a second pump (10) in order to produce such a water flow in the radon-releasing means as results in effective radon release. The radon-releasing means is in air communication (7, 34) with the surroundings of the reactor tank, so that air, via this air communication, is entrained with the water, which is supplied to the radon-releasing means via the mixing means, with a view to admixing air with the water and, hence, releasing the radon.</p> |
