2022 AWWA Water Quality Technology Conference (WQTC)
Duke Energy Convention Center
Join us at the premier conference for water quality, 2022 AWWA WQTC.
We’re excited to be a silver-level sponsor and presenting at the 2022 Water Quality Technology Conference. We hope you will join us as we share research, case studies, and insight on topics such as:
- Selecting treatment technology to improve taste & odor
- Optimizing a treatment plant to maximize carbon life and minimize life cycle costs
- Advancing treatment opportunities in water reuse
- Case studies for managing PFAS at utilities
Our WQTC Conference Sessions
Monday, November 14
Lessons Learned on Road to Compliance | 11:30 a.m.
- Speaker: Pierre Kwan
Taste & Odor – Source to Treatment
Dealing with Taste & Odor Issues from Watershed to Tap for Maryville, MO | 1:15 p.m.
The City of Maryville, Missouri, is currently experiencing issues with harmful algal blooms in Mozingo Lake, their surface water supply, resulting in taste and odor events within the distribution system. Long-term solutions will look at major rehabilitation work at the existing plant, or construction of a new WTP designed for treating surface water with T&O. HDR assisted the city with several short-term mitigation measures to reduce T&O while the ultimate long-term solution is developed, including implementing an algaecide application program for control of HABs, and installation of a granular activated carbon contactor at the existing WTP for removal of T&O.

A Unique Cost Optimization and Breakthrough Forecasting Tool for PFAS Adsorption with GAC | 3:15 p.m.
The presentation showcases a unique operating cost optimization tool for PFAS treatment with GAC. The tool combines a cost model for organics removal via convention treatment (coagulation/flocculation/sedimentation/filtration) and an adsorption model that predicts breakthrough curves for PFAS compounds based on carbon type, influent TOC and PFAS concentration, and operational setpoints. The combination of these approaches results in an optimization tool for the whole plant to maximize carbon life and minimize life cycle costs. This is applied to two case studies, Greensboro, NC, and Cape Fear Public Utility Authority, to demonstrate that it can be used broadly by utilities across the U.S. to save significantly on GAC costs.

Recognizing Successes in Biological Treatment Advanced Operations
Who are the Worker Bees in Biofiltration? Using Bioinformatics for Operational Adjustment | 8:15 p.m.
This presentation will share results from a one-year biofilter benchmarking study that goes beyond traditional biofiltration monitoring to understand biological and physical performance to enhance operation. The benchmarking focuses on characterizing biofiltration efficacy for several advanced techniques like next generation sequencing, ATP coupons, and surrogate water quality monitoring at different loading rates (up to 6 gpm/sf) and ozone doses. The results of the study will demonstrate how to use NGS/bioinformatics to inform operational adjustments to ozone-biofiltration systems.

Advancing Treatment Opportunities in Reuse
Our wAAter Program: Implementing Indirect Potable Reuse in Maryland | 2:30 p.m.
To improve long-term water supply resiliency and water quality in the Chesapeake Bay, the Anne Arundel County, Maryland Our wAAter Program is evaluating different management strategies to reduce nutrients and provide augmented water supply options to the region. This presentation will highlight the County’s approach to implementing managed aquifer recharge as part of indirect potable reuse. The presentation will provide results from characterization of WRF effluent and steps taken for implementing a non-membrane-based pilot treatment train.

Managing PFAS at Utilities: Pilot – and Full-Scale Results
Managing the Unknown Unknowns in PFAS Treatment: Implications of Pilot Scale Results on Full Scale Design | 1:30 p.m.
The City of Greensboro has been operating a year-long pilot study to evaluate GAC, ion exchange, and nanofiltration membranes to treat PFAS. This presentation will cover PFAS results from the study along with key findings that impact full scale design. Additional focus areas include managing bioaccumulation when treating PFAS in surface waters, how PFAS treatment techniques aid in the removal or mitigation of other emerging contaminants and managing the impact of waste streams.
- Speaker: Katie Walker

PFAS Treatment on a Postage Stamp Site: Aqua NJ’s Lawrenceville Well Station | 4 p.m.
The state of New Jersey was one of the first to adopt a Maximum Contaminant Level for PFAS compounds in drinking water. Aqua NJ intends to meet this new regulatory requirement utilizing Anion Exchange treatment at their Lawrenceville Well Facility. This project involved treating multiple groundwater sources, including two wells under direct influence of surface water. The presentation will describe obstacles encountered during the selection of a treatment technology as well as other operational considerations which were taken into account during the design phase.
