The phosphorus in pig manure makes it costly to dispose of the manure. The reason for this is that it requires the disposal of many cubic meters to meet current processing criteria. By separating your pig manure it is possible to create a solid part with a phosphorus level three times higher than usual. Therefore you have to dispose of much less cubic meters, which decreases disposal costs.
By separating manure it is possible to make great savings on manure disposal costs. Below are the possibilities to decrease disposal costs:
A big advantage of the liquid part derived from pig manure is that it can be easily processed in a biological air scrubber. In this machine the liquid part is evaporated and the minerals that are not evaporated stay behind. Thereby a mineral concentrate is created that can be used as a fertiliser. The solid part can be easily processed; this is even possible at a company level. This way, a pig farmer can clean his manure with the use of a hygienisation container. By processing the manure locally the farmer can export his manure himself; therefore there is no need for an intermediary.
For the NA-processing of the solid part we also supply hygienisation containers. These closed containers air the solid part though the bottom to lessen smouldering. Through this process the manure is heated to 60 degrees Celcius, killing all the bacteria and creating sterile manure which may be exported.
Liquid part from a jack screw press is a very interesting product for NA-processing because the small particles it contains are not crushed, contrary to a decanter or centrifuge. Hereby it is possible to crack the manure through a bacteriological process and produce a mineral concentrate. The solid part is easy to spread. There are no clogging issues.
Solid part can also be used against sand-drift. The solid part can be mixed with water inside the manure container in this case. This way, the solid part can be spread with a slurry tank and deflector plate, sand-drift is hereby prevented.
Sediment is a simple yet unique way to improve the separation of manure. When slurry is separated a stackable solid part and liquid part are created. The Keydollar manure separator is known for being a separator that separates the solid and liquid part well; however, there will always remain some sediment in the liquid part. This sediment sinks usually to the bottom and contains the remaining phosphate. It is therefore interesting to once more separate the solid sediment. Hereby even more phosphate can be extracted from the manure. Our separators are well known for their unique synthetic layer around the screw that makes the separation of sediment possible, this is not possible with other brands of jack screws press. Many farmers already make use of sediment from the liquid part to attain even higher results. By purchasing settling pails or tanks, it is possible to drain off the liquid part that still remains on top of the sediment to make it so the sediment remains and can be separated again. This is a simple yet effective way to optimally separate the manure.
Because you can regard solid part as solid manure, it makes it that there is much more storage capacity in your manure cellars. A stackable solid part is created that can easily be stored and can be kept on the dunghill. This way you can save on storage space for 5 to 15% by separating manure.
