Working with What You Have: Optimizing Secondary Treatment Performance in Existing Plants

Using Primary Sludge as a Supplemental Carbon Source

Thursday, April 19
4:00 PM - 4:50 PM
Location: Meeting Room 313, Sacramento Convention Center

SWRCB Wastewater: 0.1 CEU

CWEA: 1 Contact Hour

Practice Area: Team Challenge Area: Nutrient Management and Removal

Biological nutrient removal facilities often utilize methanol or other chemicals as a supplemental carbon source for denitrification. This session will illustrate the pitfalls of relying on steady-state modeling for designing biological nutrient removal facilities while highlighting how dynamic modeling was used to identify a cost-effective, chemical-free supplemental carbon source.

Learner Outcomes:

Level: Intermediate; working knowledge of subject matter / journeyman level staff
