Abstract

The objective of this research was to address the application of dedicated struvite reactors for full-scale pork production operations by: (1) Investigating a method that quickly identifies maximum struvite precipitation, accounting for real-time variations of magnesium demand within the manure slurries. (2) Developing and testing a short-retention-time pilot-scale reactor that: (a) Effectively and reliably reduces DRP in a variety of swine manure slurries; (b) Provides separation and recovery of precipitated struvite for TP reduction; (c) Can be effectively applied to modern pork production systems across a variety of manure management systems.
