Japanese Patent JPS60176300
Kind Code:
U
Abstract:
A water aeration apparatus is used for aeration purposes in the water-filled areas such as dams, impounded water or reservoirs, and lakes and marshes, and includes a tubular casing and supply chamber that causes large quantities of water to be exposed to the flotation action of air supplies under pressure, thus raising the water up to the surface. The apparatus may be used for water purification, or for anti-freezing purposes particularly in cold climate regions. The apparatus includes a collective tubular casing and a multiple-partitioned or common air supply chamber below the casing, the tubular casing including a plurality of tubular air and water passages formed by dividing the interior of the casing into several longitudinal passages by combining individual tubes together.
