A combined approach to maximize wet weather treatment is the topic of the open access article in the August 2017 edition of Water Environment Research (WER).
“In their paper on wet weather clarifier performance, Daigger et al. introduce a strategy to increase capacity by mitigating the effect of increased solids and hydraulic loading using a step-feed flow regime,” said Tim Ellis, WER editor-in-chief. “Using the City of Akron’s Water Reclamation Facility as a test case, the team used modeling and computational fluid dynamics to determine that the wet weather capacity of the existing facility could be more than doubled using the step feed strategy and minor clarifier improvements. Effluent limits with respect to BOD5, TSS, ammonia, and total phosphorus were met during wet weather excursions using this strategy.”
Selected WER articles such as this one are available free to the public on a monthly basis through an open-access program. In addition, authors can pay a fee to make their accepted articles open access.

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.
The Water Environment Federation (WEF) is a not-for-profit technical and educational organization of 33,000 individual members and 75 affiliated Member Associations representing water quality professionals around the world. Since 1928, WEF and its members have protected public health and the environment. As a global water sector leader, our mission is to connect water professionals; enrich the expertise of water professionals; increase the awareness of the impact and value of water; and provide a platform for water sector innovation.
