Details: Idaho wastewater operators and other water professionals are invited to attend. Each class in this series will provide current operational staff with complete knowledge of wastewater fundamentals. This class can help prep for the wastewater treatment examinations. The online wastewater school provides operators with a review of the current practice for each topic in wastewater treatment. If activated sludge has never made sense to you, but engines and other mechanical devices do, then this is the course for you. Inspired by the chief of maintenance at a Colorado WWTP, this course looks at activated sludge from a mechanical perspective. It introduces bacteria as the little combustion engines that they are. Seeing the mechanical inputs makes the inner workings of activated sludge crystal clear. This course introduces participants to the basics of activated sludge. It presents fundamental concepts such as space loading, F:M ratio, MCRT, SRT, solids loading and flux to the secondary clarifier, and surface overflow rate. We focus on how each of these variables is interrelated and how changing one necessarily changes the others. We will compare typical ranges for conventional and extended aeration-activated sludge plants.
