Tetra Tech RTW developed the original Activated Sludge Troubleshooting Chart to present a clear, systematic approach to defining the nature of activated sludge control problems in order to determine appropriate actions for achieving more favorable plant operation.  The second edition of this classic operators’ aid employs a new, more readable format and discusses eleven additional conditions not addressed in the original chart.  Further, the 24” X 36” poster is now laminated, equipped with a dry-erase pen, and accompanied by a searchable digital manual in CD format.
