This paper provides a critical review and analysis of the commonly accepted relationship between filament content and SVI, and demonstrates that a basic misconception of this relationship, propagated for the last three decades, has been based on an artifact of data presentation. This appears to be an original hypothesis that corrects what appears to be an error in the commonly accepted theory of activated sludge bulking, and so it seems likely to have a broad appeal to both researchers and practioners. The work is about 90% complete.
