Study on Pharmaceuticals Removal by Activated Sludge Treatment

Abstract

- This study refers to the fate and elimination during activated sludge treatment of Permethrin and Atenolol pharmaceuticals found as pollutants in wastewaters. So, using the SimpleTreat model is estimated the pollutants removal efficiency by biodegradation in activated sludge as a function of retention time (2, 5 and 10 hours). As predicted by the model, the results are correlated with pollutants properties, i.e. biodegradation rate constant and solubility in the liquid phase.
