Advance Notice of RFPs

The Water Research Foundation is pleased to provide this advance notice of requests for proposals for six new water reuse research projects that will be co-funded by WRF, the State Water Resources Control Board in California (SWB), and contributors to the Advancing Potable Reuse Initiative as part of the SWB Grant.
Requests for Proposals for each of these projects will open in Fall 2019 and will be available on WRF’s Current RFP web page. Additionally, WRF is providing opportunities for utilities and other organizations to participate in these research projects through the Utility Participation in Research (UPIR) process. Please contact Kristan VandenHeuvel for additional information.
The projects and their stated objectives are:
Guidelines for the Demonstration of Pathogen Log Removal Credits in Wastewater Treatment (5047)
  • Develop guidance for crediting wastewater treatment plants with pathogen log reduction values.

Integrating Real-Time Collection System Monitoring Approaches into Enhanced Source Control Programs for Potable Reuse (5048)
  • Determine what level of real-time collection system monitoring is feasible, appropriate, and/or necessary for protection of downstream potable reuse.
  • Develop a framework for integrating real-time monitoring into existing pretreatment program requirements (permits, local limits, etc.), including data management and security considerations.

Public Health Benefits and Challenges for Blending of Advanced Treated Water with Raw Water Upstream of a Surface Water Treatment Plant in Direct Potable Reuse (5049)
  • Define the benefits and challenges of conventional water treatment processes and their implication to public health protection.
  • Provide guidance on how to optimize conventional treatment of blended advanced treated water and raw water.
  • Explore pathogen credit validation approaches for conventional processes (i.e., coagulation, flocculation, sedimentation, and media filtration) when advanced treated water is added prior to conventional processes.
  • Explore the benefits of adding advanced treated water to surface water treatment plants after filtration and prior to disinfection.

Applicability of the UV/Chlorine Advanced Oxidation Process (AOP): Assessment of Applicability, Operational Issues, and Potential By-Products (5050)
  • Understand the current state of the science of UV-chlorine AOP.
  • Provide a framework for a utility to make the decision regarding which AOP is most suitable to their particular treatment application, both in the context of reverse osmosis-based treatment and in alternative treatment approaches (e.g., ozone bio-filtration).
  • Detail the photochemical mechanisms of oxidation, identification of radical species, and dependency on pH, UV dose, and chloramine concentration.
  • Assess the dynamic and unique operational challenges of operating a UV-chlorine AOP system including identification of critical control points, challenges with regard to monitoring, and management of by-product formation potential.
  • Utilize traditional analytical chemistry together with state-of-the-art methods, including non-targeted analysis and in-vitro bioassays to evaluate the existence of, or potential for, formation of by-products.

Geochemical Considerations for Managed Aquifer Recharge (MAR) Implementation in Potable Reuse (5051)
  • Estimate the influence of geochemical conditions on the fate of regulated and unregulated contaminants during MAR.
  • Identify advanced water treatment (AWT) effluent water quality parameters of interest (e.g., ORP, TDS, pH, and alkalinity) for aquifer compatibility, including the impact of disinfection on geochemistry.
  • Develop direction for stabilizing AWT effluent to mitigate mobilization of aquifer geochemistry (e.g., arsenic, chromium) prior to recharge.
  • Provide guidance to utilities considering MAR that includes potential application point impacts (e.g., shallow vs. deep well), water quality compatibility considerations, and monitoring techniques for risk mitigation.

Standardizing Methods with QA/QC Standards for Investigating the Occurrence and Removal of Antibiotic Resistant Bacteria (ARB)/Antibiotic Resistance Genes (ARG) in Wastewater and Advanced Treated Water (5052)

  • Develop consensus on a standardized metagenomic approach to profiling ARB and ARGs that can be used to generate comparable data that would eventually be used to validate the analytical methods.
  • Identify QA/QC components and data quality objectives.
