Water Environment Research Open Access Article Investigates Activated Sludge Modeling

The open access article for the March 2016 edition of Water Environment Research (WER) investigates ways to improve sludge production predictions in the activated sludge process by examining the extent to which un-biodegradable organic fractions are actually degradable.

“In their paper on activated sludge solids modeling, Friedrich et al., used the oxygen uptake rate in batch tests to show that a portion of the organic material previously thought to be non-biodegradable was in fact slowly biodegradable,” said WER Editor-in-Chief Tim Ellis. “To help improve the activated sludge process, the authors propose an amended approach that combines volatile solids and oxygen uptake measurements to better distinguish this fraction.”

Selected WER articles such as this one are available free to the public on a monthly basis through an open-access program. Click here to download, “Experimental Assessment of the Degradation of “Unbiodegradable” Organic Solids in Activated Sludge,” by M. Friedrich, I. Takács, and Jens Tränckner.

Published by the Water Environment Federation since 1928, WER is a popular professional journal that features peer-reviewed research papers and research notes, as well as state-of-the-art and critical reviews on original, fundamental, and applied research in all scientific and technical areas related to water quality, pollution control, and management.

Originally known as the Sewage Works Journal, WER is available in both print and online formats and receives approximately 400 new research submissions each year.
