Selectively wasting poorer settling particles can promote not only better settling sludge, but also retainment of microorganisms beneficial for nitrification and a reduction in pathogens. This paper summarizes results from a pilot study of selective sludge wasting using hydrocyclones at a facility in Wichita, Kansas as well as the design for a full-scale hydrocyclone facility that will be constructed in a BNR upgrade of the City's Plant 2 WRRF.
