Foaming-associated filamentous bacteria were isolated from activated sludge of a commercial wastewater treatment plan and identified as Gordonia species by 16S rDNA sequencing. Chlorinating Filamentous Bacteria. Why you may hesitate to chlorinate for filament control?Tried IT before and things got worse. Overdone! Your fellow wastewater treaters scared you off. Not done! Krishna Khairnar, Preeti Pal and Waman Paunikar. Activated sludge plants (ASP) are associated with the stable foaming problem worldwide. Apart from the physical and chemical treatment methods, biological treatment method have been least explored and may prove to be a novel and eco-friendly There are a number of types of filamentous bacteria which proliferate in the activated sludge process.Identifying the genus is usually specific enough to determine the role of the organisms found in a wastewater treatment system. Abstract Excessive growth of filamentous bacteria in activated sludge wastewater treatment plants (WWTPs) can cause serious operational problems.The availability of culture-independent molecular methods now allows us to identify many of the more common filamentous organisms encountered in Last Updated on Sun, 17 May 2015 | Wastewater Bacteria.By identifying the filamentous organisms that are responsible for operational problems, the operational conditions that permit the rapid and undesired growth of the filamentous organisms also can be identified (Table 15.3). One location great exchange of ideas, information and help. Category Archives: Filamentous. August 5, 2014 by WWHF Administrator Leave a comment.
