Deadline: 21-Nov-23
The Water Research Foundation (WRF) is requesting proposals for the Advancing Anoxic Phosphorus Uptake for Highly Efficient Simultaneous Nitrogen and Phosphorus Removal Project.
Project Objectives
- Advance the knowledge of phosphorus (P) removal through anoxic P uptake in biological nutrient removal (BNR); this includes investigating the microbial ecology and approaches for identification of as well as the role of denitrifying polyphosphate accumulating organisms (dPAOs), denitrifying glycogen accumulating organisms (dGAOs), non-canonical PAO, and other denitrifies that offer advantages in effective anoxic phosphorus uptake and removal with various carbon pools.
- Building on research-to-date, advance the knowledge of dPAO selection and enhancing dPAO activity in practice at pilot- and full-scale.
- Develop design and operational guidelines and control strategies focused on effective full scale implementation of anoxic P uptake for simultaneous nitrogen (N) and P removal at water resource recovery facilities (WRRFs).
Budget
- Applicants may request up to $200,000 in WRF funds for this project.
- Project Duration: The anticipated period of performance for this project is 24-36 months from the contract start date.
Outcomes
- The overall desired outcome of this project is to provide utilities with guidelines and best practices for implementing anoxic P uptake and removal in their BNR processes and sustainably achieving both N and P removal.
- This project should also advance the knowledge of P removal through anoxic P uptake (potentially with short-cut nitrogen removal processes such as PdNA and/or with carbon enrichment through RAS or mixed liquor fermentation); improve the understanding of operational aspects related to ecology and management of carbon sources (including internally-stored carbon) and alternative electron donors; and enhance dPAO activity in the presence of complex carbon pools.
Eligibility Criteria
- Proposals will be accepted from both U.S.-based and non-U.S.-based entities, including educational institutions, research organizations, governmental agencies, and consultants or other for-profit entities.
- Researchers who are late on any ongoing WRF-sponsored studies without approved no-cost extensions are not eligible to be named participants in any proposals.
- WRF encourages participation from water utilities and other organizations in WRF research. Participation can occur in a variety of ways, including direct participation, in-kind contributions, or in-kind services.
