the increased presence in wastewaters, rivers and other aquifers is of environmental
concern. The search for new technologies that can solve the problem is imperative. This
work proposes the use of activated sludge for paracetamol (PARA) removal. Different
PARA concentrations were tested (0.4, 0.5, 0.6, 0.8, and 1 mg L-1) in a batch reactor
with a working volume of 4 L. The uptake values increased with increasing initial PARA
concentration, from 0.104 to 0.341 mg g-1, in agreement with the theoretically expected.
The removal percentage ranged from 93.3 to 98.8 decreasing with the increase on the
initial concentration. The removal mechanism is well described by the pseudo 1st order
model and pseudo 2nd order model, for all concentrations tested.info:eu-repo/semantics/publishedVersio
