Monday, May 20 | Tour

Tour A: HRSD’s Nansemond Treatment Plant and SWIFT Research Center
Monday, May 20, 12:30 p.m. – 5:00 p.m.

Join us for a tour of the HRSD SWIFT Research Center, a 1 MGD indirect water reuse demonstration at the Nansemond Treatment Plant. The education and research center houses the advanced water treatment process which consists of flocculation/sedimentation, ozonation, biologically active filtration, granular activated carbon, UV, and then aquifer recharge. We will also tour the Nansemond Treatment Plant, a 5-stage ABAC process with anaerobic digestion and sidestream phosphorus recovery already implemented. WASSTRIP, Partial Denitrification/Anammox, and sidestream partial nitritation/anammox are in construction. Presentations by HRSD will cover current and future work. Note: Lunch is not included, so please eat ahead of this.

MABR is experiencing accelerated adoption due to its ability to offer process intensification in combination with energy savings and potential N2O mitigation. At the same time researchers continue to study the fundamentals and new potential applications for this technology. This session will explore these areas in two parts.

1. From theory to modeling to practice. What makes MABR unique and how it can be modeled. This will be followed by a practitioner perspective of how MABR technology is being used today to deliver value for utilities. This includes process configurations, value propositions, and key learnings from full-scale and research interests such as the fate of N2O.
2. Emerging Applications. Experts from the three leading MABR technology suppliers will provide their perspectives on new applications for MABR, including sidestream treatment, coupling with other intensification solutions, and synergies with hydrogen production.
