The development of process kinetics for a waste treatment system utilizing filamentous microorganisms
… waste treatment system designed to utilize filamentous microorganisms were defined in this study. Various chemical and physical tests such as pH, suspended solids, COD, BOD, sludge production, and oxygen utilization were used to determine the effects of parameters like flow rate, support …

Factors affecting the growth of Nostocoida limicola II and other filamentous microorganisms in activated sludge systems
… responsible for the prolific growth of various filamentous microorganisms in the bulking activated sludge at the Hoechst Celanese wastewater treatment plant. First, futile attempts were made to isolate the filamentous bacterium, <i>Nostocoida limicola II</i>, from activated sludge for purposes …

The effect of high purity oxygen on the activated sludge process
… concentration is susceptible to takeover by filamentous microorganisms. A model was proposed to explain this phenomenon. Results also suggest that it is not the use of oxygen which is responsible for differences in substrate removal rates and yield observed between air and oxygen activated …

The effect of anoxic selectors on the control of activated sludge bulking and foaming
… uptake to occur predominately by floc forming microorganisms while the high substrate removal efficiency ensures that a feed-starve cycle is created whereby filamentous microorganisms are selected against. The reported metabolic mechanisms responsible for substrate uptake in the selector are …
