Open Requests

WERF funds water research on behalf of its subscribers, and facilitates collaboration among organizations seeking funding partners for high-priority issues. WERF awards a contract through a competitive process and coordinates an independent technical review project through a staff-assigned project manager. All qualified entities – including international organizations and disadvantaged business enterprises – are encouraged to submit research proposals. 

There are currently three open requests.

Design and Implementation of Peracetic Acid for Municipal Water and Wastewater Related Processes (LIFT14T16)
Understanding the Impacts of Low-Energy and Low-Carbon Nitrogen Removal Technologies on Bio-P and Nutrient Recovery Processes (NTRY13R16)
Unintended Consequences of Resource Recovery on Overall Plant Performance: Solving the Impacts on Dewaterability Properties (NTRY12R16)

Peracetic acid (PAA) use for wastewater effluent disinfection is an emerging practice, and is of interest to many utilities seeking alternatives to the use of chlorine gas, sulfur dioxide gas, and sodium hypochlorite. However, the measurement of PAA residual in wastewater applications is limited and an approved EPA test method does not exist. WERF, in partnership with several Texas utilities, is seeking proposals to examine the effects of PAA on aquatic life, as well as its effects on water- and wastewater-related processes, and to provide guidance on the use of PAA as a disinfection method. The research results will be a product of the Leaders Innovation Forum for Technology (LIFT) Disinfection Technology Focus Area.

Anticipated WERF Cost: The total WERF cost/budget for this research effort is anticipated to be about US $200,000 thanks to the Upper Trinity Basin Water Quality Compact (made up of the Trinity River Authority of Texas, Fort Worth Water Department, North Texas Municipal Water District, and Dallas Water Utilities), Austin Water Utility, and El Paso Water Utilities. 

Anticipated Period of Performance: The anticipated period of performance is to be twelve (12) to fifteen (15) months from notice to proceed (NTP). The NTP is planned to be issued to the selected proposer after WERF’s Board of Directors’ approval in April 2016, with an anticipated project start date of June 1, 2016.

Proposals Due: Wednesday, February 17, 2016

Understanding the Impacts of Low-Energy and Low-Carbon Nitrogen Removal Technologies on Bio-P and Nutrient Recovery Processes (NTRY13R16)

Water Environment Research Foundation (WERF) research has identified the high benefit of low-energy, low-carbon nitrogen removal processes and the impact that struvite harvesting can have on phosphorus recovery from municipal water resource recovery facilities (WRRFs). However, the two recent WERF projects on low-energy, low-carbon nitrogen removal and phosphorus recovery (INFR6R11 and NTRY1R12, respectively) did not look at the combined effect of trying to accumulate phosphorus in biosolids in a low-energy, low-carbon nitrogen removal process.

Therefore, WERF is funding research to examine how phosphorus accumulation and recovery are impacted when combined with a low-energy, low-carbon process (such as mainstream deammonification). The primary goal of this project is to conduct bench, pilot, and/or full-scale studies to determine the design and operational impacts of incorporating enhanced biological phosphorus removal (EBPR) or other phosphorus recovery techniques into a low-energy, low-carbon nitrogen removal process at a WRRF. The focus of the research is on processes that are at or near the full-scale demonstration or implementation phase, and would be applicable to the existing infrastructure present at the majority of municipal WRRFs. 

Anticipated WERF Cost: The anticipated WERF cost/budget for the research effort is expected to be a minimum of US $125,000.

Anticipated Period of Performance: The anticipated period of performance is to be between 18 to 36 months from notice to proceed (NTP), depending on matching funding. The NTP will be issued to the selected proposer after receiving WERF’s Board of Directors’ approval in April 2016, with an anticipated project start date of June 1, 2016.

Unintended Consequences of Resource Recovery on Overall Plant Performance: Solving the Impacts on Dewaterability Properties (NTRY12R16)

Program Area: Resource Recovery

E-mail: cradke@werf.org

Over the last few years, WERF has funded research on the removal and recovery of nutrients from wastewater systems. It has recently been reported that water resource recovery facilities (WRRFs) that operate for enhanced biological phosphorus removal (EBPR) and/or phosphorus recovery are experiencing difficulties with the dewatering of anaerobically digested biosolids. WERF is seeking proposals to build upon the prior and ongoing body of research to determine if this phenomenon is more widespread, and to better understand dewaterability performance and its impact on overall resource recovery operations. The primary goal for this research effort is to identify pathways for improving bio-P biosolids dewaterability in relation to EBPR and phosphorus recovery.

Anticipated WERF Cost: The total WERF cost/budget for the research effort is US $175,000. The budgeted amount (including in-kind/in-cash contributions) is expected to cover the entire scope of work of the research team.

Anticipated Period of Performance: A notice to proceed (NTP) is planned to be issued to the selected proposer after WERF’s Board of Directors’ approval in April 2016, with an anticipated project start date of June 1, 2016.
