    Pilot-scale phosphorus recovery from mobile toilet wastewater in Bangkok, Thailand by Thanakrit Neamhom, Pakasinee Yakam, Chalermkiet Bathbumrung, Wirunya Tachavarong, Varakorn Kosaisavee, Yada Pinatha

    Published 2025-01-01
    “…Moreover, P leaching in soil predominantly occurred after the 7th day among the various soil types with the 90-days dissolution efficiency in soil of 97.7 ± 0.6, 86.9 ± 4.1, and 88.0 ± 3.0 for sandy loam, silt loam, and clay loam, respectively. These findings underscore the viability of achieving substantial phosphorus recovery through the utilization of a struvite-phosphate forming reactor via chemical precipitation, with additional evidence suggesting effective leaching of pellets in sandy loam soil, thereby highlighting its potential for widespread implementation in both phosphorus recovery and struvite fertilizer production on a large scale.…”
