  • Case studies showcasing advances in water treatment
  • Developing lead service line inventories and replacement strategies

Our WQTC Conference Sessions

Monday, November 6

Advances in Treatment 
The Our wAAter Program: Progressing Advanced Water Treatment in Anne Arundel County, Maryland | 11:30 a.m.  

This presentation will provide guidance on implementing a carbon-based advanced water treatment approach for indirect potable reuse. Water quality results from the water reclamation facility (WRF) sampling plan, strategies for selecting an appropriate treatment train, and lessons learned from pilot startup and operation will be shared with the audience.

Contaminants and Technologies of Emerging Concern
Divergent Technologies Converge in North Carolina – Treating PFAS and 1,4-Dioxane at PTRWA | 10:30 a.m.

The Piedmont Triad Regional Water Authority has conducted numerous bench- and pilot-scale studies to determine the optimum treatment strategy for PFAS, 1,4-dioxane, manganese, and organics. This presentation will cover the evolution of the testing strategy, conceptual treatment alternatives, and the selected processes. Technologies include reverse osmosis membranes, UV/AOP, ozone/AOP, and GAC.

Advances in Treatment 
Establishing Bioindicators and Unconventional Parameters for Improving Ozone Biofiltration Performance | 8:45 a.m.

This presentation will share results from Loudoun Water’s 18-month full-scale two-stage ozone and biofiltration study that goes beyond traditional monitoring to improve biological and physical performance. The monitoring focuses on characterizing ozone and biofiltration efficacy for several advanced techniques like next generation sequencing, ATP coupons, and surrogate water quality monitoring at different filter loading rates, ozone operation and seasonal variations. Correlating removal of emerging constituents with the microbial community provides an advanced database for optimizing ozone biofiltration operations. These innovative monitoring tools and advanced bioindicators will help to alert plant staff to potential water quality upsets.

Microbial Community Characterization Using High-Throughput Sequencing for Operations Optimization of an Ozone-Biofiltration | 9:15 a.m.  

Biofiltration treatment processes have become advantageous due to their high removal efficiencies of turbidity, organic compounds, unwanted tastes and odors, and pathogens with minimal if any chemical additives and lower energy requirements. These systems are highly dependent on the microbial communities present, but these communities can be impacted by seasonal and operational changes. Better understanding the impacts of operations and influent water quality on biofiltration systems is important for advancing water treatment technologies and to provide high quality, biostable drinking water.

Optimizing Ozone and Biological Filtration to Address Taste & Odor Issues for Maryville, MO | 11 a.m.  

The City of Maryville, Missouri, is currently experiencing issues with harmful algal blooms in Mozingo Lake, their surface water supply, resulting in significant taste and odor events with geosmin concentrations exceeding 2,000 ng/L. The long-term solution selected by the city is construction of a new WTP designed for treating surface water with T&O. The city recently completed an 11-month pilot scale study to prove and optimize the selected treatment process of ozone followed by biological filtration. The pilot scale project was designed to test the process against multiple challenges including seasonal water conditions, induced extreme T&O events, and even intermittent operations.
