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:

Novel photocatalytic reactor for water purification
TL;DR: In this paper, a novel photocatalytic reactor design for water treatment is characterized by the use of new extremely narrow diameter lamps, thus allowing for much higher surface area for catalyst coating per unit reactor volume and consequently for higher specific reactor capacity.

Optimization of Hydrodynamic Cavitation Using a Model Reaction
TL;DR: In this paper, the effect of various parameters (inlet pressure, flow geometry of orifice plates) on the iodine liberation rate has been studied, and it is found that the flow geometry has a significant impact on the rate of the iodide removal.
Journal ArticleDOI
Decomposition of organophosphorus compounds on photoactivated TiO2 surfaces
TL;DR: In this paper, a mechanism of degradative oxidation on the TiO2 particles involving epoxidation by surface peroxo species and direct hole oxidation is proposed, which enhances dramatically the rate of catalytic activity by inhibition of the electron and hole back-reaction as well as direct oxidation of the substrate species by the strong oxidants themselves.
