Sludge Settling

During a brief period of low pH in the primary aeration basin of an industrial wastewater treatment system, severe sludge settling problems (i.e., bulking) occurred. Microscopic examination of the sludge solids revealed a profusion of fungal hyphae disrupting proper floc formation. A yeastlike fungus was isolated from the sludge capable of growth on compounds common to the treated chemical waste and with a preference for lower pH values. The fungus, identified as Geotrichum candidum, disappeared from the sludge upon raising the pH of the aeration basin with the concomitant return of normal settling characteristics.
