Combination of Advanced Oxidation Processes and biological treatments for wastewater decontamination—A review
TLDR
The main conclusions arrived at from the overall assessment of the literature are that more work needs to be done on degradation kinetics and reactor modeling of the combined process, and also dynamics of the initial attack on primary contaminants and intermediate species generation.About:

Gaining further insight into photo-Fenton treatment of phenolic compounds commonly found in food processing industry
Sara García-Ballesteros,M. Mora,R. Vicente,C. Sabater,Maria-Angeles Castillo,Antonio Arques,Ana M. Amat +6 more
TL;DR: In this paper, a mixture of eight phenolic compounds, namely 2,4-dinitrophenol, tannic, ellagic, gallic, protocatechuic, vanillic, syringic and sinapic acids, have been treated by means of a photo-Fenton process under simulated and real sunlight.

Photocatalytic and biological oxidation treatment of real textile wastewater
TL;DR: In this paper, the use of TiO2 as photocatalyst and the effect of the addition of H2O2 on color removal was investigated, and their combination resulted in a high extent of color removal (93.3%), and chemical oxygen demand (COD) reduction (90.4%).

Performance evaluation of a novel pilot-scale pinned disc rotating generator of hydrodynamic cavitation
Jurij Gostiša,Brane Širok,Sabina Kolbl Repinc,Marjetka Levstek,Marjetka Stražar,Benjamin Bizjan,Mojca Zupanc +6 more
TL;DR: Experimental results show that at a given rotational speed and liquid flow rate, the pinned disc generates more intense cavitation than the serrated disc, while also consuming less energy per liquid pass, which is comparable to the best cases of lab-scale orifice and venturi devices operating at much lower wastewater processing capacity.
