Elevated Organic Acid Concentrations: Filamentous bulking from many recognized filamentous bacteria morphotypes is correlated with elevated concentrations of low molecular weight organic acids. Generally, >80 mg/L of volatile acids is a recognized cause for selection of these filaments. Organic acids may be naturally occurring in many industrial wastes and septage or may be formed in areas of septicity/fermentation (i.e., collection systems, lift stations, eq basins, primary clarifiers).
