Bug of the Month: Filament Type 0092 and Wastewater Treatment

One way Eickelboom filament type 0092 is unique is that for morphotype identification purposes, Neisser positive staining characteristics must apply. Filament type 0092 diameter is typically between 0.8-1.0 µm and these filament types are generally less than 200 µm in length. Type 0092 filaments are usually located within the floc, and if they are causing/contributing to filamentous bulking, it is usually due to these filaments creating open/diffuse flocs. In certain issues, type 0092 filaments appear capable of also growing dispersed. The recognized growth cause of type 0092 filaments is elevated concentrations of low molecular weight organic acids. Organic acids are a
