What is Phosphorus Recovery from Wastewater and Sewage Sludge as Vivianite about?

Developing feasible techniques to recover phosphorous (P) from wastewater and sewage sludge is urgent work to meet the huge demand for P resources and wastewater/sludge management. Recently, recovering P as valueadded vivianite (Fe 3 (PO 4 ) 2 ⋅8H 2 O) has aroused great interest due to the convenient process operation, high recovery efficiency, and wide applications of vivianite. In this review, qualitative and quantitative detection methods of vivianite have been first analyzed, providing reference to test vivianite content and purity. Advanced technologies for P enrichment and vivianite production, including ion exchange, electrodialysis, capacitive deionization, membrane bioreactor, anaerobic fermentation, chemical precipitation, electrochemical crystallization, biomineralization, and anaerobic digestion are then comprehensively summarized. Mechanisms and representative applications of each technique are emphasized. Also, critical parameters (e.g., pH, Fe/P molar ratio, sulfate concentration, microorganisms, supersaturation index, organic matters, and seed crystals) affecting vivianite formation have been systematically analyzed. Furthermore, perspectives regarding fast detectio
