title: Efficient control of activated sludge filamentous bulking by means of a multi-component additive.
abstract: A multi-component additive formulated for a more efficient control of activated sludge filamentous bulking was evaluated at a full-scale treatment plant experiencing a severe filamentous bulking. It was found that, besides offering an immediate improvement of sludge settling, the multi-component additive was able to eliminate the filamentous bacteria causing the bulking. Hence, contrarily to ordinary additives, this novel additive yielded immediate as well as long-term improvement of sludge sedimentation upon a few additions.
