A Village Struvite Reactor Turning Source-Separated Urine into Fertiliser: Design and Phosphorus Budget for a 100-Person Community

Design and full phosphorus budget for a batch struvite precipitation reactor for 100 people, calculated from a deposited script. SIMULATED, NOT MEASURED. The reactor is calculated to recover 87.8% of urine phosphorus at pH 9.0 and 2.0 h residence, producing 2.31 kg of struvite per person per year, and stops paying on fertiliser value alone when magnesium oxide exceeds 1.23 USD per kg.

Abstract

Design and full phosphorus budget for a batch struvite precipitation reactor for 100 people, calculated from a deposited script. SIMULATED, NOT MEASURED. The reactor is calculated to recover 87.8% of urine phosphorus at pH 9.0 and 2.0 h residence, producing 2.31 kg of struvite per person per year, and stops paying on fertiliser value alone when magnesium oxide exceeds 1.23 USD per kg.
