9:30-12:00 in Salon H-G: International UV Association Joint Workshop

Bacteriophage Regulations and Potential Impacts on Reuse Systems

As the president of the IUVA, Kati is deeply engaged in regulatory policy that could impact UV systems that are used for reuse. Currently, the EPA is developing a new ambient water quality criteria for bacteriophage which could have significant impact on wastewater reclamation facilities that are utilizing UV for disinfection; Kati will provide an overview of the status of the criteria development and how the criteria could impact UV systems for reuse.

Water Polishing of Municipal Wastewater Intended for Water Recycling Using a Novel Biocatalyst Technology

Nutrient residuals in wastewater effluent have negative impacts on receiving water matrix and cause issues for water reuse. A novel biocatalysis technology is tested in laboratory bench experiments and pilot-scale trials at a municipal wastewater treatment plant for nutrient removal targeting nitrogen and phosphorous.

Treatability and Chemical Stability Effects of Supply Augmentation with High-Purity Recycled Water at a Drinking Water Treatment Plant 

As potable reuse grows, it is critical for existing drinking water treatment plants to adjust to supply augmentation with high-purity recycled water, which affects both treatability and chemical stability. In this study, bench-scale experiments demonstrated that recycled water blends could be flocculated and made filterable; and that lime and alkalinity were both required to achieve positive LSI.  Michael will discuss these interesting results and their implications for drinking water systems in the age of potable reuse.

10:30-11:00 in Salon G-H: Innovations in Industrial Reuse

The Use of Reclaimed Water for Power Plant and Wetland Rehydration Applications: Evaluation of Technologies to Meet Fit For Purpose Water Quality

About 75 to 80% of all existing and proposed power plants are within ten miles of a municipal wastewater treatment facility.  However, only sixty of five thousand power plants are currently using municipal reclaimed water for cooling tower applications in the US. With the funding from the Water Environment & Reuse Foundation, the authors are evaluating the effectiveness of traditional and innovative treatment technologies for nitrogen and phosphorus removal from a secondary treated wastewater for these specific reuse applications at an electric utility in Florida. Dr. Badruzzaman will provide an overview of the opportunities to reuse reclaimed water for industrial reuse and wetlands rehydration purposes, particularly at an electric utility in Florida.

Natural Gas Versus Grid Electricity for Seawater Desalination: An Economic and Environmental Life-Cycle Perspective

Traditionally, seawater desalination plants purchase electricity from the grid, which often is associated high unit cost and carbon footprint. An alternative energy source may allow desalination plants to reliably meet the increasing energy demand and reduce the associated environmental impacts. In recent years, the application of natural gas (NG) and liquefied natural gas (LNG) has been considered as a potential alternative to grid electricity at selected SWRO plants. Dr. Badruzzaman will discuss the economic and environmental cost-benefits of liquefied natural gas (LNG)/ natural gas (NG) for self-generation of power at desalination plants and for running high pressure pumps using gas engines versus grid electricity on a life cycle basis for a range of installations (5-150 MGD).

3:30-5:30 Big Picture Session: Water Supply Resiliency

Achieving Water Independence through the Sustainable Water Infrastructure Project

The City of Santa Monica’s Sustainable Water Infrastructure Project is an integrated water resources approach to advance treat stormwater runoff, salinity-impaired brackish groundwater, and recycled municipal wastewater for immediate non-potable reuse and, when properly permitted, for indirect potable reuse via reinjection to provide drought resiliency and help maintain the long term yields of  the City’s aquifers. This project illustrates how distributed local projects – including stormwater treatment plant upgrades, new brackish water wells, a new advanced treatment plant for wastewater reuse, and improved stormwater collection – can be combined for cohesive approach for water supply reliability in a built out urban environment.

11:00-11:30 in Salon G-H: Potable Reuse Quality

Cost-effective Nitrogen Management Strategies for Potable Reuse

For potable reuse applications, the quality of the effluent produced from the upstream wastewater treatment plant affects the operational performance and the effluent water quality of the downstream Advanced Water Treatment (AWT) Facility.  Nitrogen Management plays a crucial role for AWT facilities.  Removal of ammonia, typically achieved at higher SRTs, improves the performance of the downstream membrane processes at the AWT facility whereas removal of nitrate is required to meet potable water quality standards.  This paper evaluates different system-level nitrogen management strategies for AWT facilities treating non-nitrified secondary effluent.

2:00-2:30 in Salon A-B:Seawater Desalination

Conventional Versus Membrane Based Pretreatment Processes for Seawater Desalination: Perspectives from Full-Scale Operating Plants

Seawater desalination using reverse osmosis (RO) has increased substantially in the recent past and is expected to grow at a faster rate in the future.  The successful operation of a RO plant depends on the ability of the pretreatment system to consistently produce filtered water for the RO process.  Both conventional (e.g., conventional/lamella sedimentation, dissolved air flotation, granular media gravity/pressure filter) and membrane based pretreatment processes (e.g., microfiltration, ultrafiltration) are operational worldwide. Although most of the currently operational pretreatment systems are conventional, low-pressure membrane-based pretreatment systems are increasingly being considered for future plants.  This presentation will provide some technical and non-technical perspectives from a variety pretreatments for seawater RO plants in various parts of the world.

9:30-10:00 in Salon G-H: Water Quality and Data Analytics

The Need for Application of Predictive Analytics for Potable Reuse

In direct potable reuse (DPR), absence of the environmental buffer may shorten failure response times and potentially require more stringent effluent water quality or process monitoring goals. This paper provides an overview of application of predictive analytics as an alternative performance monitoring tool that uses historical and current data sets to forecast future probabilities of the occurrence of an event that impairs specific DPR processes.
