| Research Abstract |
Filamentous bacteria belonging to the phylum Chloroflexi were frequently identified in activated sludge systems, where their presence seriously compromised liquid/solid phase separation in the secondary clarifiers. In municipal wastewater treatment plants, particularly in summer, levels of these filamentous Chloroflexi correlated with biomass sludge volume index. Also, a competitor probe was designed for the precise identification of filamentous Chloroflexi in FISH experiment. A hydrophilic polytetrafluoroethylene membrane was developed to allow effective liquid/solid phase separation of activated sludge.
