FILAMENTOUS ORGANISMS CAUSING ACTIVATED SLUDGE BULKING AND THEIR IDENTIFICATION

In This paper first the ninety years of identification of filamentpous bacteria causing bulking was reviewed on what achievments was made for each of the three distinguished periods: the first when Spaherotilus natans was concluded as the main causative organism, the second when filamentous bactyeria were classified by Eikelboom TYpes and the third when FISH a specific biomolecular Method was developed and applied.
