Research Category: Sustainable and Healthy Communities , P3 Awards , P3 Challenge Area - Safe and Sustainable Water Resources
Objective:
The primary objective of the P3 Phase II award was to build and test a field-scale prototype of the three-step ammonia scrubber. At the completion of the Phase I award, a laboratory-scale prototype of the second step, the adsorption column, was built and tested. In year one of the Phase II award, the team focused on building and testing steps one and two of the field-scale prototype under laboratory conditions. The team also tested the efficacy of the ammonia-enriched biochar as a soil amendment, which was not discussed in the original scope of work.
Progress Summary:
In year two of the Phase II award, the team focused on moving the field-scale prototype from laboratory to the field, and on optimization and feasibility under field conditions.
In a previous reporting period, we noted that undergraduate students were not allowed in laboratories until ~March 1, 2020, which was the start of the previous reporting period. For this reporting period students were partially online and partially in-person and so no student team was formed to continue work on this project.
Future Activities:
We have recruited a new team to finish this project. A one-year NCE was requested to allow the 2022-2023 team to wrap up the project and participate in the spring P3 Expo, if held. Our plans for completing the project include developing a market feasibility and applicability report, and to determine if this project can be optimized and economically feasible at scale. We are optimistic for the future of this project.
