Water aeration apparatus.

摘要

The apparatus is used for aeration purposes in water-filled areas such as dams, impounding reservoirs, and lakes and marshes, and causes large quantities of water to be exposed to the lifting action of air to be supplied under pressure, thus raising the water up to the surface through the above means. The apparatus may be used for water purification, or for anti-freezing purposes particularly in the cold climate regions. The apparatus comprises a column (2) and a multiple-partitioned or common air supply chamber (3) below. The column (2) has a plurality of longitudinal air and water passages (1) which are provided by dividing the interior of the column into several longitudinal passages or by combining individual tubes together.
