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.

Wittmer et al. (2015) investigated the change in UV absorbance of wastewater effluent before and after ozone treatment as a simple control strategy to optimize ozone dose for micropollutant removal. Laboratory batch experiments were carried out using wastewater effluent from 3 different Swiss WWTPs (Eawag, Werdhölzli and Uster).

For Mitigation of Filamentous Bulking Sludge & Reduction of Pharmaceutical Discharge

Alleviation of filamentous bulking sludge and reduction of pharmaceutical residues are both possible to achieve with ozone. This thesis presents results from two full-scale installations focused on mitigation of filamentous bulking sludge as well as one pilot-scale trial in which ozone was combined with a pre-treatment to remove pharmaceuticals from treated wastewater.

Schaar, et al. (2010) investigated the efficiency of a pilot-scale ozonation in removing micropollutants from the effluent of a full-scale biological WWTP in Austria. The WWTP was upgraded from high-loaded to low-loaded with nutrient removal.
