Question: A watertreatment plant periodically has problems sludge bulking, the question was to analyse with ORVIdetect quantitative PCR to gain insight into the filamentous growth in the sludge.
Work done: ORVIdetect analyses for several filamentous micro-organisms were performed on the sludge. At the moment of sampling, the treatment plant did not have problems with bulking sludge.
Results: The filamentous bacteria Microthrix parcivella was found in low amounts in the WWTP.
