The Solution: Dairy Specialists, the local Centrisys dealer, designed a system using a slope screen to process all of the flushed down manure and sends about two-thirds of the screened manure back through the process for flushing. Additional screened manure, less than one-third, is sent through a Centrisys CS21-4HCDT centrifuge. Using a centrifuge allows the centrifuged manure, which is sent to the final lagoon, to consistently contain less than 1.4% TSS and reduce phosphorus by almost 50%. This minimizes the solids accumulation in the lagoon and makes the liquid manure easier to run through center pivot irrigation. The two-stage solution, designed by Dairy Specialists, minimizes the overall volume of water and makes the final centrifuged liquid manure easier to manage.
