A review of imperative technologies for wastewater treatment I: oxidation technologies at ambient conditions
TL;DR: In this article, the authors highlight five different oxidation processes operating at ambient conditions viz. cavitation, photocatalytic oxidation, Fenton's chemistry, ozonation, and use of hydrogen peroxide.
Journal ArticleDOI
A review of imperative technologies for wastewater treatment II: hybrid methods
TL;DR: 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.
