The goal of this project is to develop a novel approach of concomitant stabilization of fresh source-separated urine with preferential struvite precipitation using a sacrificial MG anode and carbon-based gas-diffusion cathode.activities:the activities include developing and testing a pilot-scale novel electrochemical treatment system to stabilize urine waste and separate and recover nutrients such as nitrogen and phosphorous. The team will evaluate performance of continuous recovery system by conducting life-cycle and techno/economic analysis.subrecipient:no subawards are included in this assistance agreement.outcomes:the anticipated deliverables include annual and a final report. Additionally, the project will provide results across several scales relevant to developing electrochemical processes for treating source-separated urine. The expected outputs include a development and design of an electrochemical process: to 1) prevent the transformation of fresh source-separated urine to the putrid liquid that results from urea hydrolysis and microbial growth, 2) stabilize and precipitate the recoverable nutrients, n and p, from urine in a form that may be recovered for recycling in agriculture, and 3) reduce n and p released to the environment degrading quality of natural water bodies. Direct beneficiaries of this program include residents of the communities in south carolina state, the general public, and the environment.
