The activated sludge process is very widely used for biological wastewater treatment. This 2 hour course includes background on biological wastewater treatment, a general description of the activated sludge process, information about several variations of the activated sludge process, discussion of design calculations for an activated sludge aeration tank, and discussion of activated sludge operational calculations. Example calculations and discussion of using an Excel spreadsheet for making the calculations are also included.
This course is intended primarily for civil engineers, environmental engineers, and chemical engineers. After completing this course you will be familiar with the common variations of the activated sludge process used for biological wastewater treatment and be able to make typical aeration tank design and operational calculations.
