The study has been carried out during September 2006–January 2007 at Wastewater Treatment Plant Constanţa Sud and it had the aim to identify main microorganisms responsible for bulking upsets. A comparative survey of abundance and size of floc-forming and filamentous bacteria has revealed that proportion of these bacterial groups could significantly change at different sludge volume index (SVI) values. Dominant filamentous bacteria have been identified as Eikelboom type 0041, Nostocoida limicola, and Sphaerotilus natans. It seemed that their proliferation would be supported by oxygen fluctuations and fully mixed operational mode of the treatment plant.
