Next Steps: Secondary Clarification Design and Operation as the Result of Aerobic Granulation

Aerobic sludge granulation is an area of interest from both a research and implementation standpoint. Significant advancements have occurred at both the lab and full-scale levels that have furthered understanding on primary mechanisms for granule formation. As this work continues to advance a necessary compliment to this is also how sludge granulation impacts other processes, specifically secondary clarification. This paper and presentation will begin to highlight the potential considerations related to clarification, underflow, and influent configurations as they relate to sludge granules. One well understood aspect of sludge granulation is the increased clarification capacity as a result, however realizing and taking advantage of this capacity must also be understood.
