TL;DR: First-order rate constants for pharmaceutical removal, normalised to biomass, were significantly higher compared to other studies on activated sludge and suspended biofilms, especially for diclofenac, metoprolol and atenolol.

TL;DR: In this article, a pilot plant consisting of six moving bed biofilm reactors (MBBRs) in series was built to integrate Biological Oxygen Demand (BOD) removal, nitrification and denitrification as well as prepolishing Chemical O2 Demand (COD) for ozonation.

TL;DR: Results show that trimethoprim was eliminated by ozone easier than other pharmaceuticals, and fluorescence was found to be highly correlated to the removal of pharmaceuticals.

TL;DR: The effect of humic acid, as a model for complex organic substrate, was investigated in relation to the biodegradation of pharmaceuticals by suspended biofilm carriers adapted to polishing effluent water from a tertiary sewage treatment plant and shows that the presence of complex substrate stimulates degradation via a co-metabolism-like mechanism and competitive inhibition does not occur.

TL;DR: It is confirmed that ozone can improve RAS water quality, a better understanding of the ozone decay mechanisms that can be used to define further safe ozone treatment margins are provided, and that fluorescence could be used as a monitoring tool to control ozone.
