摘要
The procedure consists of transferring the manure to storage tanks to flocculate and concentrate suspended matter. Each tank has a skimmer for concentrating phosphorous in aqueous form, and a potassium extractor to recover and remove the potassium after liquefying. The hydro-injectors, skimmers and extractors are mounted on floats keeping them on the surface of the manure. The procedure consists of transferring the manure to storage tanks (1) in which it can be subjected to the action of one or more hydroinjectors (2) to flocculate and concentrate suspended matter, and especially potassium in solid form, on the surface. Each tank has one or more skimmers (3) for concentrating the phosphorous in aqueous form, and one or more potassium extractors (4) to recover and remove the potassium after liquefying it. The hydro-injectors, skimmers and extractors are mounted on floats (6) that keep them on the surface of the manure, the floats being immobilized by ropes, cables or other systems holding them to the base of the tank. The hydro-injectors are powered by turbines and create currents in the manure by means of injected air and a venturi system to provide oxygenation and flocculation of suspended organic and mineral matter. The tank also has a submerged pump for discharging liquid, actuated by a level sensor.
