A Soft Sensor for Simultaneous Prediction of Struvite Purity and Recovery Rate. [PDF]

ACS Omega
Phosphorus is essential for all living organisms and is widely used in various industries. However, phosphorus resources are nonrenewable and may soon be depleted. Struvite, a high-quality slow-release compound fertilizer containing nitrogen, phosphorus, and magnesium, is a form of phosphorus recovery product.

Strategies to enhance the recovery of phosphorus as struvite during the storage of urine

Results in Engineering
Phosphorus is a non-renewable resource, and it will in future become increasingly scarce. Urine can be used as a valuable resource of phosphate. One way to create favourable conditions for recovering phosphorus as struvite from urine is to store urine ...

Phosphorus recovery by struvite precipitation: a review of the impact of calcium on struvite quality [PDF]

Journal of Water, Sanitation and Hygiene for Development, 2021
Abstract Precipitation of phosphorus (P) as a struvite product from wastewater and local magnesium (Mg) sources is considered as a high economical prudent venture, as it has shown to bring down the cost of producing the product. However, there is a significant concentration of calcium (Ca) in these Mg and most wastewater sources.
