Troubleshooting/Optimizing Activated Sludge Operations

Sessions dates and times (PDT) - 7 hours Total, .7 CEUs

Sep 29 (8 am - 10:10am, 11:10am - 1:20 pm), Oct 1 (8 am - 10:10am, 11:10am - 12:20 pm)

This goal for this workshop is for attendees to evaluate their treatment system and develop a list of opportunities to improve and optimize their plant operation. This course is for experienced operators and managers of activated sludge plants. A microscopic floc assessment including filament identification should be conducted prior to the workshop so we know the present sludge quaility conditions that can be applied in the workshop. Topics specific to successful activated sludge operations will be covered. At the conclusion of the workshop attendees will leave the workshop with a comprehensive plan to implement at their facility to improve/optimize plant performance.
