Ecophysiology of the filamentous Alphaproteobacterium Meganema perideroedes in activated sludge.
A comprehensive study of the ecophysiology of the filamentous Meganema perideroedes affiliated to the Alphaproteobacteria, possessing a "Nostocoida limicola Type II" filamentous morphology was conducted. This morphotype often causes serious bulking problems in activated sludge wastewater treatment plants, and hardly anything is known about its physiology. The study was carried out by applying a...
متن کاملEcophysiology of abundant denitrifying bacteria in activated sludge.
The abundance of potential denitrifiers in full-scale wastewater treatment plants with biological nitrogen and phosphorus removal was investigated by FISH and various oligonucleotide probes. The potential denitrifiers were characterized as probe-defined populations that were able to consume radiolabelled substrate with oxygen, nitrate and nitrite as electron acceptor as determined by microautor...
متن کاملInfluence of different anoxic time exposures on active biomass, protozoa and filamentous bacteria in activated sludge.
Medium-sized wastewater treatment plants are considered too small to implement anaerobic digestion technologies and too large for extensive treatments. A promising option as a sewage sludge reduction method is the inclusion of anoxic time exposures. In the present study, three different anoxic time exposures of 12, 6 and 4 hours have been studied to reduce sewage sludge production. The best ano...

متن کاملReliability of Morphological Approach for Bulking Filamentous Bacteria Identification in Activated Sludge Plants
Activated sludge process is the most commonly applied technology for the biological treatment of wastewater. However, operational failures and deterioration of treatment efficiency due to extensive and uncontrolled growth of filamentous bacteria have been reported worldwide as common problems of this method. Over the years, various methods have been developed and applied for the identification ...
