AIR LITT REACTOR

Airlift reactors are submerged reactors in which energy input is achieved by applying gas. Compressed air is often used as gas. During operation, compressed air enters the air transport reactor at the bottom through the gas distributor. The added air mixes with the contents of the reactor and rises in the form of air bubbles. Rising air bubbles cause upward flow. By doing so, some of the oxygen in the air dissolves into the water. The area with the upward flow is called the ascending column. The remaining air bubbles leave the water at the top of the reactor. The gas-free liquid is returned to the lower section of the reactor parallel to the riser. The area with the downstream flow of an air transport reactor is called the drop tube. During operation, the contents of the reactor are recirculated through the riser and downcomer. This recirculation is superimposed by perfusion in continuous operation. For this purpose an additional tank with feed pump is provided.
