The Department of Energy Advanced Research Projects Agency awarded the University of Connecticut a $3.758 million cooperative agreement on February 27, 2026, under the Advanced Research Projects Agency-Energy program (CFDA 81.135) to demonstrate an integrated process for simultaneous recovery of ammonia and phosphorus from anaerobic digesters.

The project will combine ceramic vacuum membrane distillation and bipolar membrane electrodialysis with ZwitterCo superfiltration membrane pretreatment to develop an intensified anaerobic digestion with resource recovery (IADRR) approach. The system targets recovery of over 90% of ammonia and phosphorus as high-value liquid products while increasing methane yield through digester detoxification. The work directly addresses inhibition of methanogenesis caused by high ammonia concentrations and phosphorus discharges that contribute to eutrophication in wastewater resource recovery facilities.

Performance occurs in Storrs, Mansfield, Connecticut, with a period of performance through February 26, 2029. The University of Connecticut's Office Sponsored Programs administers the award as the prime recipient.
