Abrégé

The invention relates to a method for gassing liquids, in particular for aerating water, wherein gas is fed to a mixing tube (2) via a gas inlet (7) and liquid via a liquid inlet (13) such as to form a mixture of gas and liquid, which is characterised in that the liquid is introduced centrally via a feed pipe (12) and the mouth opening (13) of the latter into the mixing pipe (2) and is spread in the region of the mouth opening (13) by means of an impact onto a spreader (18).

Abrégé

The present invention relates to an artificial aquifer for decreasing the contents of metals, metalloids, nitrate, nitrite, pesticides and organic micro contaminants in natural ground water or artificial infiltrated groundwater from surface water. The system comprising a basin ( 1 ) of filling material creating a reaction zone (5) a feeding line (3), one or more satellite wells (4), at least one main well (6) and a pumping well (7). whereby the feeding line (3) is applied in the upper outer periphery of the basin ( 1 ) and wherein the main well (6) is connected to a pumping well (7) via a bottom outflow provided with a regulating valve to maintain a given level of water in the aquifer The invention further relates to a method for purifying water.
