In the June issue of Water Environment Research (WER), an open-access research article explores the best model to use when examining the fate of microconstituents in wastewater.

In the article, “General Fate Model for Microconstituents in an Activated Sludge System,” researchers discuss evaluating biodegradation models for the microconstituents 17-ethinylestradiol, bisphenol-A, and triclosan. The study identifies biotransformation as the principal removal mechanism for microconstituents and the pseudo-second-order model as the most accurate.

“In their research on microconstituent removal in activated sludge systems, Banihashemi and Droste found that the solids retention time played a major role in developing a large enough degrading population to accomplish pollutant removal,” said Tim Ellis, WER editor-in-chief. “Evaluation of the mass flux of microconstituents in the system showed that biodegradation and not adsorption was the dominant removal mechanism. The authors determined that a pseudo-second-order model best described the removal rate.”
