ABSTRACT:
Organic constituents in a liquid, such as a waste water from a municipal or industrial process (e.g. bleach plant extraction liquor from the bleaching of paper pulp) may proceed effectively without the addition of alkali. When the organic constituents are reacted with an oxygen containing gas at appropriate pressure and temperature conditions, oxidized organics and gaseous acidic products of oxidation (e.g. CO.sub.2) that are produced are continuously and immediately removed from the liquid so that they do not significantly contribute to lowering of the pH of the liquid, so that the reaction may proceed and the liquid remain alkaline. This may be accomplished in a gas sparged hydrocyclone in which the liquid is introduced into the first end of a vortex while oxygen is introduced from exteriorly of the vortex into contact with the liquid, or may be accomplished by causing the liquid to flow in a thin film in a downwardly extending spiral path and removing the acidic gases from a center portion of the spiral path. A reactor for effecting the last mentioned specific procedure includes a pressurized vertical vessel having a downwardly extending stationary spiral surface mounted in the vessel substantially concentric with it. Surface manifestations may be provided on the spiral surface for enhancing mixing of liquid with surrounding gas.
