Nocardia takedensis sp. nov., isolated from moat sediment and scumming activated sludge.
Yamamura H, Hayakawa M, Nakagawa Y, Tamura T, Kohno T, Komatsu F, Iimura Y. Yamamura H, et al. Int J Syst Evol Microbiol. 2005 Jan;55(Pt 1):433-436. doi: 10.1099/ijs.0.63189-0. Int J Syst Evol Microbiol. 2005. PMID: 15653914
Chemotaxonomic and morphological characterization of two actinomycete strains, MS1-3T and AS4-2, respectively isolated from moat sediment and scumming activated sludge, was carried out. This characterization clearly demonstrated that strains MS1-3T and AS4-2 belong to the …

Candidatus Kaistella beijingensis sp. nov., Isolated from a Municipal Wastewater Treatment Plant, Is Involved in Sludge Foaming.
Song Y, Jiang CY, Liang ZL, Zhu HZ, Jiang Y, Yin Y, Qin YL, Huang HJ, Wang BJ, Wei ZY, Cheng RX, Liu ZP, Liu Y, Jin T, Wang AJ, Liu SJ. Song Y, et al. Appl Environ Microbiol. 2021 Nov 24;87(24):e0153421. doi: 10.1128/AEM.01534-21. Epub 2021 Sep 29. Appl Environ Microbiol. 2021. PMID: 34586909 Free PMC article.
K. beijingensis was not a core node among the WWTP community network, but its abundances were negatively correlated with those of the well-studied BFB Skermania piniformis among cross-season Qinghe WWTP communities. IMPORTANCE Biological foaming, also known as scumming, is …

Partial ozonation of activated sludge to reduce excess sludge, improve denitrification and control scumming and bulking.
Böhler M, Siegrist H. Böhler M, et al. Water Sci Technol. 2004;49(10):41-9. Water Sci Technol. 2004. PMID: 15259936
Partial ozonation of the return sludge of an activated sludge system reduces significantly excess sludge production, improves settling properties of the sludge and reduces bulking and scumming. The solubilized COD will also improve denitrification if the treated sludge is …

An examination of the mechanisms for stable foam formation in activated sludge systems.
Petrovski S, Dyson ZA, Quill ES, McIlroy SJ, Tillett D, Seviour RJ. Petrovski S, et al. Water Res. 2011 Feb;45(5):2146-54. doi: 10.1016/j.watres.2010.12.026. Epub 2010 Dec 28. Water Res. 2011. PMID: 21239035
With non-hydrophobic cells, an unstable foam was generated, and in the absence of surfactants, cells formed a greasy surface scum. Addition of surfactant converted a scumming population into one forming a stable foam. The ability to generate a foam depended on a threshold …

An investigation into studying of the activated sludge foaming potential by using physicochemical parameters.
Hladikova K, Ruzickova I, Klucova P, Wanner J. Hladikova K, et al. Water Sci Technol. 2002;46(1-2):525-8. Water Sci Technol. 2002. PMID: 12216681
The relations among activated sludge and biological foam hydrophobicity, scum index, aeration tank cover and filamentous population are evaluated. Individual parameter comparison reveals the scumming intensity can be estimated only on the assumption that foams is already e …
