Sustainable Nutrient Recycling: Development of Decentralized Technologies for High-Yield Nitrogen and Phosphorus Recovery from Source-Separated Urine - 2

We are sorry, this position has been filled.

The overarching aim of this study is to develop decentralized technologies for the high-yield recovery of both nitrogen and phosphorus from source-separated urine, by utilizing waste or low-cost streams to achieve high cost-effectiveness. The proposed method integrates membrane contactor (MC) with crystallization. Specific objectives include (1) investigate the principles governing ammonia vapor transport across hydrophobic microporous membranes in MC, (2) study nutrient recovery from source-separated urine using waste/low-cost heat and chemical streams in an integrated membrane contactor-crystallization process, and (3) provide fundamental thermodynamic understanding of the intrinsic energy requirements and second law efficiencies of nutrient recovery/removal.
