How Do Different Odor Management Approaches Impact Downstream Processes? Nutrient Removal, Harvesting, and Odor Control Assessed through Whole Plant Sulfur Modeling

Abstract

Odor control modeling has not been a focus of treatment plant modeling in the past, but not because of a lack of importance. Large facilities in North America can spend over $1 M USD on chemical addition and operation annually. While sewer process models such as WATS and SeweX are widely used for sulfide modeling in collections systems, integrated sulfur models for whole plant process optimization and design are still not well used in practice. Historically, odor control was often viewed as a separate "black box" from whole plant process simulation work without a significant consideration for overall process impacts. The inclusion of sulfur cycling in whole plant simulation tools has given process engineers a new tool of investigation for whole plant impacts of odor control chemical addition. The results from TRA indicate there is value from an odor control perspective, but also from a plant wide operation and nutrient harvesting perspective. Increased use of whole plant modelling in combination with collection system odor control modelling can further increase the accuracy of future evaluations.

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

Abstract

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.
