PROCESS AND APPARATUS FOR SIZED NUTRIENT RECOVERY FROM WASTEWATER BY ELUTRIATION

摘要

Processes and apparatus are provided for recovery of dissolved species from wastewater streams, in the form of precipitates sized by elutriation. The processes may for example be controlled so that the recovered sized solids are in the form of relatively insoluble plant nutrients, such as struvite. The extracted nutrients may for example include solid species of phosphorus, and/or nitrogen, and/or potassium.
