Ariel Szogi, Advisor to Renewable Nutrients, has published a White Paper titled "Economic Recovery of Calcium Phosphates From Swine Lagoon Sludge Using Quick Wash Process and Geotextile Filtration". The paper comes after a Renewable Nutrients Quick Wash Pilot with a major national hog producer in North Carolina. The pilot showed how Quick Wash can efficiently remove and recover phosphorus from hog lagoons.
