PROCESS AND APPARATUS FOR IN-SITU DECONTAMINATION OF HEAVY METAL CHARGED GROUND WATER

In the process for in-situ decontamination of ground water contaminated by heavy metal ions, a ground water dome (26) is built up in a well shaft (10) by introducing gas, thus forcing the flow of ground water. This is taken through a siphon with an ion exchanger (50), to which the heavy metal ions a...

Zusammenfassung:In the process for in-situ decontamination of ground water contaminated by heavy metal ions, a ground water dome (26) is built up in a well shaft (10) by introducing gas, thus forcing the flow of ground water. This is taken through a siphon with an ion exchanger (50), to which the heavy metal ions are transferred from the water flow by application of a voltage.
