<p>Device consists of a shaft turning around a horizontal axis at a certain distance below the surface of the liq. in a tank or other recipient; the device is fitted with radial aeration blades in the form of small plates arranged at a certain distance from each other. The outside end dips into the liq, when the shaft turns. The two half blades consist of elements curved, in opposite directions, into two planes in the outside zone; the root of each blade is fixed to the shaft in a movable manner. The liq. is enriched with O2 to the max. extent with the optimum flow through the tank; both are attained with the min. of energy consumption.</p> |
