Well water cleaning

摘要

The system to clean ground water, in a well, has a gas introduced into the well pipe by gas injection or suction of emitted gas, to give a water recirculation. A carrier material to form colonies of micro organisms is built into the well.Pref. a high gas insertion is used to clean the water by stripping, or a low air supply is used to move the water without stripping. The carrier material has a lighter specific gravity than water, to give a floating bed action, or it is heavier than water to give a fixed bed working. The carrier material is secured into the well mantle zone or within the well. Air is delivered for aerobic degrading, and an inert gas is fed for an anaerobic processing.
