Filaments are most prevalent in activated sludge systems but are typically found in low concentrations in aerated stabilization basins as well. The types of filamentous bacteria present can indicate certain things about a wastewater system, like nutrient availability or dissolved oxygen concentration.
What is an example of filamentous bacteria?
The most commonly encountered filamentous bacteria causing bulking problems belong to the Alphaproteobacteria ('Nostocoida'-like), the Gammaproteobacteria (Thiothrix and type 021N), the Actinobacteria (Candidatus'Microthrix', Mycolata) and the Chloroflexi (types 1851, 0041 and 0092).
How are filamentous bacteria formed?
Filament Structure
Shifts in the activated sludge environment, such as changes in pH, dissolved oxygen, nutrients, etc. will often cause a change in the behavior of the bacteria. Instead of single cells, small chains or clumps, the bacteria will begin to form longer "chains" which develop into filamentous bacteria.
