OPERATIONAL AND ECONOMIC MODELING AND OPTIMIZATION OF MOBILE SLURRY SEPARATION

摘要: Economies of scale associated with mobile separation will reduce the costs for each individual farm. Mobile help both larger and smaller animal production units, whose plant may be unbalanced, to make efficient use slurry separation. A multiple-farm facility, comprising a decanter centrifuge mounted on trailer, has been adapted and configured. The separates raw into one fraction containing high proportion dry matter and phosphorus in slurry, another most nitrogen potassium slurry. Its operational performance terms capacity efficiency tested tools operations management have been devised. Results shows that efficiencies (%) obtained tests were 37-68, 50-83, 8-33 (DM), total phosphorus (TP), total (TN), respectively. TN was dependent DM content of manure, while TP not. The separator averaged 19.0 m3 h-1, ranging from 6.0 40 h-1. average nominal time assembling dismantling, cleaning system, 2.3 h, corresponding labor requirement 3.1 person-hours. operating strongly amount manure being treated annually, varying between 2.7 7.0 $ m-3 typical operational constraints.
