Modelo de gestão de RCD´s em territórios de baixa densidade populacional

No âmbito da gestão dos resíduos, em geral, urge a problemática dos RCD, cada vez mais actual e de grande importância, sendo o problema ainda mais marcante em zonas de baixa densidade populacional. Os RCD apresentam uma composição muito heterogénea, motivo pelos quais as suas fileiras devem ser separadas em obra e posteriormente encaminhadas para a indústria recicladora. O planeamento e os meios postos à dispos...

Strategies to enhance the removal of Fluoroquinolones

Fluoroquinolones (FQs) are broad-spectrum antibiotics that play an important role in the treatment of serious bacterial infections. Currently, several FQs are available but ciprofloxacin (CPF), ofloxacin (OFL) and norfloxacin (NOR) are amongst the most worldwide prescribed antibiotics. Antibiotics can reach wastewater treatment plants (WWTP) from different routes. Thus removal of these contaminants during the b...

Studies on enantioselective biodegradation of fluoxetine

Fluoxetine (FLX) is a chiral fluorinated pharmaceutical indicated mainly for treatment of depression and is one of the most dispensed drugs in the world. There is a clear evidence of environmental contamination with this drug. Granular sludge sequencing batch reactors (SBR) constitute a promising technology for the treatment of effluents containing micropollutants. In this study, a SBR was operated in order to...

Pharmaceuticals biodegradation by activated sludge and pure cultures

The occurrence of pharmaceuticals in the environment have been a topic of increasing concern. Most of the pharmaceuticals are not completely mineralized in the human body and are released on the sewage systems as the pharmaceutical itself and as their “biologically active” metabolites through excretion, as well as by improper elimination and disposal. Once current wastewater treatment plants (WWTPs) are not des...
