The New Hampshire Department of Environmental Services will host a two-day class on advanced activated sludge process control on Oct. 20-21 at the Susan N. McLane Audubon Center in Conord. The class will be taught by Eric Wahlberg, PE., Ph.D., of WasteWater Technology Trainers, Fountain Valley, California. 

The class will give give activated sludge front-line supervisors and operators — and process control operators and engineers — a more in-depth understanding of the activated sludge process. With this understanding, effluent quality variability and process energy usage can be reduced. Topics to be presented include: wastewater characterization, biological N&P removal, the importance of sludge quality, measuring and controlling sludge quality, WAS flow control, BOD conversion vs. removal, RAS flow optimization, secondary clarifier performance diagnostic testing, and a state point analysis. Paper copies of the presentation will be provided. 

As WasteWater Technology Trainers’ president and primary instructor, Wahlberg is an operator, engineer and Ph.D. The Water Environment Federation has awarded him many awards for his efforts in research, contribution to operations and operational problem solving. He is well known for his work in developing activated sludge process control and performance tests and has written and presented extensively on those subjects. Wahlberg is also a nationally renowned expert in primary and secondary clarifier operations. More info:

The registration fee for the workship is $120, which includes lunch for both days. A total of 13 hours of training will give each participant 1.3 CEUs. You must attend both days to receive credit. 

The registration deadline is Sept. 28.
