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

ABSTRACT: 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. It is typically recovered by applying magnesium salt chemicals to nitrogen- and phosphorus-rich wastewater. Struvite purity and recovery rate are critical quality parameters that dominate its market price and feasibility as a fertilizer. Traditional methods for determining the struvite purity and recovery rate involve complicated sample preparation and analysis processes, which are labor-intensive and would be adverse to the automation of continuous analysis during large-scale struvi
