Water Environment Research’s (WER) newest open access article is on a combined approach to maximise wet weather treatment.
“In their paper on wet weather clarifier performance, Daigger et al. introduce a strategt to increase capacity by mitigating the effect of increased solids and hydraulic loading using a step-feed flow regime,” Tim Ellis, editor-in-chief of WER, said. “Using the City of Akron’s Water Reclamation Facility as a test case, the team used modelling 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 improvement. Effluent limits with respect to BOD5, TSS, ammonia, and total phosphorus were met during wet weather excursions using this strategy.”
Selected WER articles, much like this one, are available free online to the public on a monthly basis through an open-access programme, and Marry Step Feed with Secondary Clarifier Improvements to Significantly Increase Peak Wet Weather Treatment Capacity: An Integrated Methodology, by Glen T. Daigger; John S. Siczka; Thomas F. Smith; David A. Frank; and J. A. McCorquodale, can be downloaded from WER’s website.
