ABSTRACT:
An aerating apparatus or aerator for expelling the impurities from ground water, especially for ground water under an overpressure, in which the impurities are expelled by generating a partial vacuum in an aeration shaft in the vicinity of ground water to be purified and by feeding fresh air below the water level in the aeration shaft, the aeration shaft is closed on its upper end with a pressurized receiving chamber. The pressurized receiving chamber permits fresh air to be brought in at an air pressure balancing the ground water pressure. Moreover a vacuum generator producing the partial vacuum is located in the pressurized receiving chamber.
