Estimating the Efficiency and Cost of an On-Farm Centrifuge Separator: A Case Study

Cows generate huge amounts of manure annually on Idaho farms, organic waste that demands effective management. Centrifuges offer a more efficient system, though many state producers rely on others, like settling ponds or screens. Learn how your operation can benefit by adopting this system. Based on a yearlong study conducted in the Magic Valley in 2017, this bulletin examines the efficiency and cost of running a centrifuge on a commercial dairy. Along with reducing the amount of land needed for lagoon water and lagoon maintenance, its use also produces nutrient-rich solids, whose composting and sale can provide an extra source of revenue.
