Activated Sludge Design and Process Control in a BNR World . . . . .A Companion Program to Workshop W206

Saturday, October 18, 8:30 am – 5:00 pm
1 day, 0.6 CEUs

This comprehensive workshop is presented by leading practitioners in their specific subject areas. Sharing their experiences in an interactive environment, makes this workshop a perennial favorite with WEFTEC participants.  This workshop is a companion to a Hands-on Workshop conducted the following day at the John E. Egan Water Reclamation Plant in Chicago by many of the same instructors and more.

The moderator and presenter of the “Basic Principles on BNR”, Jan Oleszkiewicz, is a professor at the University of Manitoba and has a vast teaching and design experience that spans North America and Europe. He is noted for his ability to set the stage for the entire day’s proceedings.

Glen Daigger, Senior VP of CH2M Hill has more design and practical operations experience than any other practitioner today. His module is especially geared to solving the practical design problems that have plagued many earlier BNR systems. Of special interest are his tips for making the processes work together as a BNR system.

Along with the widespread use of BNR systems has come the realization that a design is not complete without considering the impacts from various process sidestreams. B. Narayanan, a Principal with Carollo Engineers, has put together a comprehensive study of the various sidestreams and coupled it with useful design and operational considerations.

No biological process design is going to work without a fully functioning aeration system. Dave Redmon, President of Redmon Engineering, has been the leading aeration process performance practitioner for the past decade. His insights into the actual time sensitive field performance of different types of aeration systems are an invaluable asset for those who design, operate, or maintain the final products in the real world.

Woodie Muirhead, the Senior Operations Specialist with Brown and Caldwell, has combined his many years of working with operators and biological systems with an innate understanding of the physical and biochemical interactions. His presentation on “Process Control” yields an outstanding understanding of the entire interactive BNR system.

All these design and process considerations are brought together by Ron Schuyler, a Senior VP with RTW Engineers, in his comprehensive discussion of the microbiological considerations with BNR. Ron’s thorough presentation of the needs of the specific types of microorganisms that we confront in BNR systems is a key to finally exercising control over the process.

All this talk about growing and developing the right biomass would be for naught without an understanding of how we’re going to get them to settle! John Esler, President of CPE Services, Inc., draws on his many years of experience with the full-scale field evaluation of clarifiers of all sizes and types to bring BNR clarifiers to life. This often neglected unit operation has undergone a tremendous transition in recent years, thanks to the real-life data developed by actual field evaluations.
