TLDR
In the first part of this two article series on the imperative technologies for wastewater treatment, a review of oxidation processes operating at ambient conditions was presented It has been observed that none of the methods can be used individually in wastewater treatment applications with good economics and high degree of energy efficiency Moreover, the knowledge required for the large-scale design and application is perhaps lacking as mentioned in this paper.About:

Degradation of 1,2-dichloroethane from wash water of ion-exchange resin using Fenton’s oxidation
Miia Vilve,Sari Vilhunen,Mikko Vepsäläinen,Tonni Agustiono Kurniawan,Niina Lehtonen,Hannu Isomäki,Mika Sillanpää +6 more
TL;DR: Fenton’s oxidation could be used for organic destruction of wash water of ion-exchange resin to reduce environmental load and processing costs of wastewater and increase of Fe2+ and H2O2 doses improved the removal of 1,2-dichloroethane and TOC.

Abatement of phenolic mixtures by catalytic wet oxidation enhanced by Fenton's pretreatment: effect of H2O2 dosage and temperature.
TL;DR: The integration of Fenton reagent as pretreatment of theCWO process remarkably improves the efficiency of the CWO reactor and allows to obtain detoxified effluents at mild temperature conditions and relatively low W/Q(L) values.
Journal ArticleDOI
Enhancement of chloroform degradation by the combination of hydrodynamic and acoustic cavitation.
TL;DR: A synergistic effect has been obtained by the hybrid method of acoustic and hydrodynamic cavitation and this hybrid method can be visualized as a new step for wastewater treatment.

Photocatalytic and Sonophotocatalytic Degradation of Reactive Red 120 using Dye Sensitized TiO2 under Visible Light
S.K.Kavitha,P. N. Palanisamy +1 more
TL;DR: In this paper, the effect of sonolysis, photocatalysis and sonophotocatalysis under visible light has been examined to study the influence on the degradation rates by varying the initial substrate concentration, pH and catalyst loading.
