"Area farm to try manure technology"-Ultrafiltration Trials set to Begin on Swine Manure

After working with dairy manure for the last several years, Digested Organics will launch its first pilot with swine manure in collaboration with Mercer County, Ohio next week. Ag Solutions Coordinator Theresa Dirksen helped coordinate plans for the pilot, which will primarily investigate how the ultrafilration (UF) technology we employ can remove phosphorus from swine manure. As shown in the graph below, UF typically removes 97+% of phosphorus from dairy manure and we expect similar performance with swine manure. Normally about 90 gallons of liquid (called UF permeate) with less than 0.2 lbs/1000 gal phosphorus is created for every 100 gallons of manure filtered.

Our proposal to Mercer County stated: “Performance information collected during this demonstration will allow us to size and price commercial-scale equipment, as well as determine operating costs, to give farmers and regulatory agencies in Mercer County a sense of how much this technology costs to implement on various size farms.”
