TL;DR: In this paper, the authors investigated the effect of hydroxyl-, methyl- and chloride ring substitution on the oxidation mechanism of aromatic compounds and found that the readily biodegradable COD fraction of the WAO effluents was found by respirometric techniques.

TL;DR: A CWPO treatment at ambient conditions followed by a CWAO treatment at mild conditions is presented as high efficiency process for the decontamination of phenolic wastewaters.

TL;DR: The major product formed by wet oxidation of a series of model compounds: d -xylose, d -glucose, glucose and dextran, was formic acid as mentioned in this paper.

TL;DR: In this paper, regenerated adsorbent particles are recovered from a wet oxidation-regenerated mixed sludge liquor from a wastewater treatment system by diluting and settling a blowdown slurry (20) from the wet oxidation reactor (12) to obtain a first aqueous phase (32) containing primarily regenerated particles and fine ash particles and a first solids phase (28) containing mainly grit particles.
Abstract: Regenerated adsorbent particles, such as activated carbon, are recovered from a wet oxidation-regenerated mixed sludge liquor from a wastewater treatment system by diluting and settling a blowdown slurry (20) from the wet oxidation reactor (12) to obtain a first aqueous phase (32) containing primarily regenerated adsorbent particles and fine ash particles and a first solids phase (28) containing primarily grit particles. The first aqueous phase (32) is combined with a portion (16) of the regenerated adsorbent particle slurry withdrawn from the upper portion of the wet oxidation reactor (12) and, after treatment with a dispersing agent (36) and then an anionic flocculating agent (44), the resulting mixture (46) is settled to obtain a second aqueous phase (54) containing primarily fine ash particles and a second solids phase (50) containing primarily regenerated adsorbent particles. The second solids phase (50) is recycled to the wastewater treatment system for re-use and, after treatment with a cationic flocculating agent (58), the second aqueous phase (54) is settled to obtain a substantially particle-free third aqueous phase (66) and a third solids phase (64) containing primarily fine ash particles. Slurries (28) and (64) containing the grit and fine ash particles are combined and dewatered prior to disposal.

TL;DR: In this paper, a process to limit the corrosion of the materials of construction of a wet oxidation system treating wastewaters is described. But this process is particularly useful in the wet oxidation treatment of ammonium sulfate containing wastes such as acrylonitrile wastewater.
Abstract: A process is disclosed which limits the corrosion of the materials of construction of a wet oxidation system treating wastewaters. The process is particularly useful in the wet oxidation treatment of ammonium sulfate containing wastes such as acrylonitrile wastewaters. The wastewater is mixed with an oxygen containing gas such that a substantial residual oxygen gas concentration is maintained from before the stream-gas mixture is heated for wet oxidation until after the oxidized stream-gas mixture is cooled and separated. Preferably, in the treatment of acrylonitrile waste water the shutdown procedure comprises cooling said waste stream by introducing an aqueous liquid substantially free of organic impurities and containing a basic material.
