摘要
Oxygen deficient water is aerated by dispersing bubbles of air or oxygen gas in a forced downflow of water through a downwardly diverging funnel trapping the bubbles therein for prolonged contact with the water. The bubbles are displaced by crowding from the lower end of the funnel after some of the oxygen has been absorbed in the water and in some cases partially replaced by nitrogen gas stripped from the water.
