dc.description.abstractORGANIC MICROPOLLUTANTS (OMP) IN THE HOUSEHOLD AND INDUSTRIAL WASTEWATER ARE NOT EFFICIENTLY REMOVED BY CONVENTIONAL TREATMENT PROCESSES AND A SIGNIFICANT FRACTION ENDS IN SLUDGE. PROPER VALORIZATION TECHNOLOGIES BECOME FUNDAMENTAL TO ATTAIN SUSTAINABLE SEWAGE SLUDGE MANAGEMENT, WITH ANAEROBIC DIGESTION (AD) AS ONE OF THE PREFERRED STRATEGIES. HOWEVER, IT EXHIBITS SOME LIMITATIONS THAT CAN BE OVERCOME WITH PRE-TREATMENT PROCESSES. IN THIS STUDY, THE INFLUENCE OF DIFFERENT PRE-TREATMENT CONFIGURATIONS OVER OMP CONCENTRATION AND REMOVAL DURING AD WAS ASSESSED. THE INCORPORATION OF A SEQUENTIAL US - TT-PT RESULTED IN DECREASED CONCENTRATIONS OF 7 OF THE 9 DETECTED COMPOUNDS IN BIOSOLIDS COMPARED TO CONVENTIONAL AD DIGESTATE, WITH BISPHENOL-A AND TER-OCTYLPHENOL SHOWING THE OPPOSITE EFFECT. THE RESULTS SUGGEST THAT THE ASSESSED PT COULD IMPROVE THE REMOVAL OF SEQUESTERED OR HIGHLY HYDROPHOBIC COMPOUNDS THROUGH THEIR SOLUBILIZATION AND INCREASED BIOAVAILABILITY.
