Activated Sludge Solids Inventory Control Using the State Point Concept
Author: Eric J. Wahlberg
Date: 3/296
Presented at Central States Water Environment Association Enhancing the Design and Operations of Activated Sludge Plants, Madison, Wisconsin, March 28, 1996

Activated sludge solids inventory control using the state point concept initially appears to many to be as nonsensical as "Form form from from." However, once understood (like "Form form from from"), the state point concept affords operators a powerful tool for understanding the movement of solids through the activated sludge process, for making timely process control decisions, and for optimizing the activated sludge process.
