Activated Sludge - Evolution To Nitrogen Removal: TRE-5906-16-05: P

All Wastewater, Industrial Wastewater 5, 6, and 7 (Process)

What do you know about the various activated sludge configurations currently used, available, and evolving for activated sludge, BNR, and ENR processes? The objective of this class is to give activated sludge plant operators 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, RAS flow optimization, secondary clarifier performance diagnostic testing. Specifically, types of aeration diffusers (mechanical, fine bubble, and membranes) and blowers (positive, multistage, single stage, and high speed) will be addressed. The influence of MCRT and MLSS will also be addressed as to the efficiency, ease (or difficulty) and cost of aeration. Finally, helpful operating hints will be provided based on experiences from operating facilities.
