<p>Floating apparatus (11) which consists of a preferably inflatable cover (1) intended to be positioned above known devices for aeration/oxygenation of the water and is provided with a shut-off valve (5) controlled by a float (6) and intended to regulate the flow of oxygen to the inside of the inflatable cover. The result is that no oxygen is wasted, while the cover is always kept in the inflated condition, therefore resulting in optimum transfer of oxygen to the water.</p> |
