An interesting outlook can be to combine the mining industry with membrane-based desalination in the logic of mining from the sea or wastewater. This presentation suggests membrane crystallization (MCr) for the treatment of nanofiltration (NF) retentate and reverse osmosis (RO) brine leaving membrane-based desalination system. Urine contains most of the excess nutrients excreted by humans. However, given that the use of untreated urine directly as fertilizer is generally poorly accepted, the best chance to further treatment and processing of urine. In this work, we have investigated the effectiveness of emerging and established membrane-based processes, i.e., forward osmosis, membrane distillation, ultrafiltration and their hybridisation with biological oxidation processes, in the production of commercial fertilizer using human urine as raw material. The fertiliser was then benchmarked with commercial solutions via a controlled set of hydroponics experiments.
Professor Ho Kyong Shon at the University of Technology Sydney is an Australia Research Council (ARC) Future Fellow, the President of the Membrane Society of Australasia (MSA), the Editor for the Journal of Desalination, and the Deputy Director of Center for Technology in Water and Wastewater. He specializes in understanding physico-chemical water treatment processes in water, wastewater and seawater. His research career focuses on studying advanced membrane fabrication and the application of membrane based desalination in detailing membrane fouling mechanisms and developing novel desalination technology. He has co-authored over 400 high-impact refereed journal publications (51 h-index and > 9900 total citations) including five patents and numerous international awards over the last 20 years. He is currently supervising several postdoctoral research fellows, ten PhD students and two Masters students related to membrane and nanotechnology for water purification and resource recovery.
