Separation of pig slurry using sedimentation and pressurized filtration
Languages of publication
Intensive non-bedding pig farming results in the formation of large quantities of liquid waste in the form of slurry. In areas with high concentration of pig farms where we have to deal with insufficient acreage of arable land there is often a difficulty with management of pig slurry’s surplus. The solution to this problem may become a separation of slurry into solid fraction, rich in phosphorus and liquid fraction, which contains mainly nitrogen and potassium. The paper presents the fractionation of pig slurry using sedimentation and pressurized filtration.
