Further information on the reduction of micropollutants in wastewater

Here we provide links to relevant articles and offer summaries of studies on micropollutants and its reduction from wastewater. We also discuss solutions and issues such as cost of removing pharmaceutical residue. New content will be added every month. Please feel free to comment or provide more information in any discussion.

Lester et al. (2013) investigated the applicability of ozone as a treatment step following activated sludge system to treat wastewater from a pharmaceutical formulation facility in Israel. The target drugs carbamazepine and venlafaxine were detected at extremely high concentrations in the raw wastewater therefore reducing its concentration prior to discharge into the local municipal WWTP is necessary.
