Abstract
Liquids, e.g. sewage sludge, waste water or oxygen-poor natural water, are treated with gas for enrichment (especially oxygenation) by forcing the liquid downwardly through a perforated wall in a vessel containing the liquid. The perforated partition subdivides the liquid forced downwardly through the column into a plurality of partial streams which open into a gas space above the downwardly moving column of liquid in the melt. Bubbles of the gas, e.g. oxygen, pass upwardly through the column of liquid in the shaft.
