摘要:
Method and apparatus for aerating bodies of open water utilize unbalanced water columns interconnected at their upper ends to provide continuous aeration of the water at any desired depth. The head on one column is attained by the introduction of air into the other column which serves both to raise and to aerate the water therein. Alternatively, the water may be circulated by mechanical means and the air introduced at the top of its travel. Undissolved air is permitted to escape as it passes between the columns before it enters the return column.

An installation for the treatment of sewage comprises a tank having an inner wall dividing the tank into a central digestion zone and peripheral zones of decantation and removal of treated effluents, the lower portion of the tank being in the form of a reversed truncated cone and having a series of small upwardly directed conduits connecting the bottom of the tank with the upper zone of decantation.
