MAPHEX System

Caption

The system devised by Penn State and USDA scientists -- dubbed MAPHEX for MAnure PHosphorus EXtraction -- involves a three-stage process, including liquid-solid separation with an auger press and centrifuge, chemical treatment with the addition of iron sulfate, and final filtration with diatomaceous earth. The machine is designed to process manure from manure-storage tanks or pits on dairy farms.
