Abstract

Graphical abstract: Highlights: Pallet wood was the best substrate for the immobilization of Trametes versicolor . Trickling packed and fluidized bed reactors were proved for HWW treatment. The use of complex pellets for HWW in fluidized bed reactor resulted not scalable. High removals of PhACs were obtained with a trickling packed reactor for 49 days. Abstract: Hospital wastewater is a major source of pharmaceutically active compounds (PhACs), which are not all removed in conventional wastewater treatment plants. White rot fungi can degrade PhACs, but their application has been limited to non-sterile conditions due to the competition with other microorganisms for growth. In this study, immobilization of Trametes versicolor on different lignocellulosic supports was studied as strategy to ensure fungal survival under continuous treatment conditions. A fluidized bed reactor and a trickling packed-bed reactor with T. versicolor immobilized on pallet wood were employed for the removal of ibuprofen, ketoprofen and naproxen. Best results were obtained with the trickling packed-bed reactor, which operated for 49 days with high removal values in real hospital wastewater.
