Filamentous micro-organisms in industrial plants

Filamentous bulking is still a serious problem in numerous industrial activated sludge plants.

During a six year (1998-2004), EU sponsored research program about 80 filamentous micro-organisms were observed in industrial sludges, many completely unknown so far. The samples originated from 175 treatment plants, covering a wide range of industrial sectors.

Every month one of these filamentous organisms will be presented on this website in a Pdf file. The information provided includes their morphological features, a photo and, when available, which probes should be used for identification through FISH, their nutritional requirements and control options. The complete results are summarized on a CD-ROM entitled "Identification and control of filamentous micro-organisms in industrial wastewater treatment plants (see 'our products' for ordering info).
