ABSTRACT:
A method of removing iron from ground water located in a water well and of preventing production of hydrogen sulphide in such water including positioning a bubbling device in the well below the waterline. This device, which is connected to a source of pressurized air, is operated to produce a continuous flow of air bubbles in the water to render dissolved iron in the water insoluble so that the latter precipitates out and the well water aerobic. The insoluble iron can then be gathered from the well periodically. In one version, an iron collecting device in the form of a bag is placed around the bubbling device. The bag is removable from the well in order to remove and dispose of collected insoluble iron. Calcium carbonate can be used to adjust the pH level to pH 7. When the bubbling device is introduced into water containing sulphur, the air stream of bubbles has a double action and prevents hydrogen sulphide production.
