Description

Biology of the Activated Sludge Process: The Bacteria” provides a review of the roles performed by the significant groups of bacteria in the activated sludge process. The class introduces the activated sludge process as a “river in a box” by comparing the natural cleansing action of wastewater by a river to the degradation of wastewater by the activated sludge process. Bacterial structures, e.g., cell wall, cell membrane, etc., are identified and their roles in the treatment process are presented. In addition, the response to inhibitory and toxic wastes and harsh conditions are provided. The difference between bacterial growth and reproduction (sludge production) is offered as well as a review of the bacterial “growth” curve and its relationship to sludge production. Because MLVSS does not include only bacteria, a description of the MLVSS is provided with caution in interrupting MLVSS as only bacteria. Floc formation, the “key” to successful wastewater treatment is illustrated along with acceptable floc formation and unacceptable (interruption of) floc formation. Finally, a brief description of the significant groups of bacteria is presented.
