Summary:

The objective of this research was to test a pilot‐scale air sparged tank reactor (ASTR) and the ASTR in
combination with a hydrocyclone (called the pilot‐scale ASTR‐hydrocyclone system) on two swine manure slurries for
struvite‐based (MgNH4PO4‐6H2O) phosphorus removal and recovery. It was found that in a typical Iowa deep-pit swine production facility (10,000 head/year) the annual cost of struvite‐based phosphorus removal using the struvite-based phosphorus removal system would be approximately $8.88/finished pig or $0.035/L manure slurry treated ($0.134/gal). This cost often exceeds producer’s profit margins and is not currently economically viable.
