Abstract

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).

IPC Classes  ?

• B01F 3/04 - Mixing, e.g. dispersing, emulsifying, according to the phases to be mixed gases or vapours with liquids
• B01F 13/02 - Mixers with gas agitation, e.g. with air supply tubes
• B01F 5/00 - Flow mixers; Mixers for falling materials, e.g. solid particles
• B01F 5/04 - Injector mixers
• B01F 13/10 - Mixing plant, including combinations of dissimilar mixers

Abstract

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.

IPC Classes  ?

• C02F 3/04 - Aerobic processes using trickle filters
• E03B 3/08 - Obtaining and confining water by means of wells
• E21B 43/30 - Specific pattern of wells, e.g. optimising the spacing of wells
• B09C 1/00 - Reclamation of contaminated soil

Abstract

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 ground water from surface water. The system
comprising a
basin of filling material creating a reaction zone, a feeding line, one or
more satellite wells,
at least one main well and a pumping well, whereby the feeding line is applied
in the upper
outer periphery of the basin and wherein the main well is connected to a
pumping well 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.
