Abstract
Activated sludge, as an aerobic environment rich in organic matter, often provides the optimum conditions for the development of colourless filaments. From the taxonomic point of view, these colourless filaments can be divided into three groups of basic characteristics: bacteria, cyanophyceae and fungi. The effort to distinguish these three groups is not only inspired by the endeavour to classify them taxonomically correctly, but rather by possible different physiological efficiencies of the individual groups. This may be their basic significance for the determination of technical parameters of the activated sludge process.
